Setting up your Eyedro Electricity Monitor over Wi-Fi is usually a smooth process. However, if you run into setup bumps, there is a fast, reliable backdoor method: temporarily provisioning Wi-Fi using an Ethernet connection.

Connecting your Eyedro device via Ethernet bypasses local Wi-Fi credential errors, establishes a stable connection to the MyEyedro cloud, and lets you reconfigure your Wi-Fi settings hassle-free.

1.Disconnect Power from the Eyedro Unit: Ensures the device registers hardware changes upon startup.

2.Connect to Your Router via Ethernet:

No sensors required for network configuration.

Run a standard Ethernet patch cable from an active LAN port on your router (or switch) directly into the Eyedro module’s Ethernet port.

The Ethernet cable must be plugged in before power is applied so the Eyedro recognizes the wired interface on boot.

Note: You do not need to move your current CT sensor clamps for this setup—only the Eyedro module and its power supply need to be plugged in near the router.

3.Power Cycle the Device: Forces the device to bypass old Wi-Fi settings, and also stops the device from broadcasting its WiFi network in the case of first time setup.

Plug the power adapter back into the Eyedro unit. When powered up with an active Ethernet cable attached, the unit automatically ignores existing Wi-Fi configuration settings and routes traffic over the wired LAN connection via DHCP.

4.Add Device to MyEyedro Account or Verify Device is Active if Already Claimed on account:Verify active communication.

Wait approximately 10 to 15 seconds for startup diagnostic tests to complete:

• Watch the status LEDs: A solid or toggling green light indicates successful internet communication.
• Log into your account at My.Eyedro.com. Your device should now display as Active.

5.Reconfigure or Clear Old Wi-Fi Credentials:Apply clean 2.4GHz network parameters.

Navigate to the device settings menu in MyEyedro:

1. Select Forget / Clear existing Wi-Fi credentials.
2. Enter your new 2.4GHz Wi-Fi SSID (Network Name) and Password.
3. Double-check for case sensitivity—incorrect capital letters or spaces are the most common cause of setup failures.
4. Save the new parameters.

6.Disconnect Ethernet and Return to Normal Wi-Fi Operation:Final transition back to wireless mode.

Unplug the power cord, remove the Ethernet cable, and move the Eyedro module back to its permanent installation location. Reapply power; the unit will now connect automatically to your updated Wi-Fi network.

• Verify 2.4GHz Support: Eyedro modules operate exclusively on the 2.4GHz frequency band for better wall penetration. Ensure your router does not force 5GHz-only connections on your smart home hardware.
• Hardware Generation Differences:
  • Gen 6 Devices (Serials starting with A14-1): Support Ethernet hot-swapping (plug and play at any time).
  • Gen 5 Devices (Serials starting with A14-0): Require the Ethernet cable to be connected before powering on the device.
• Firewall & DNS Issues: If the status light fails to turn green even over Ethernet, check if custom router DNS rules (like Pi-hole or AdGuard) are blocking cloud traffic. Switching temporarily to Google DNS (8.8.8.8 / 8.8.4.4) often resolves stubborn connectivity blocks.

For detailed Eyedro product specifications, installation and MyEyedro cloud software information please refer to Eyedro product guides and MyEyedro user guides.

 TRAC - Technical, Remediation & Advisory Committee

You have been and continue to be led by the nose by the above parties exactly like the original UPAC, followed by CPAC, RAC & TAG. There was a 4 1/2 year period  (2011- Aug. 2015) when CPAC wagged the dog versus Chemtura and the M.O.E.. Your colleague Sebastian Seibel-Achenbach was on that CPAC and for a very short while we had Chemtura and the M.O.E. on their heels, actually listening in trepidation to what we told them they had to do. And along came Sandy and Mark Bauman and Chemtura/M.O.E. breathed a sigh of relief as corporate order and control was restored. Under their first 21 years and last 11 years of total control over the cleanup, it has totally failed. Neither NDMA nor chlorobenzene much less DDT, dioxins and lots more solvents, chlorinated or otherwise, have been reduced to Ontario drinking water standards. Nor will they be and those parties knew that full well in 1990 and have lied to we the citizens ever since. Much greater expenditure of funds including specific DNAPL removal was needed as well as simply even following through on Target pumping rates of wells which they grossly failed to do.

Stand up and take their power, their credibility and their legitimacy away from them! They are not and have never been honest brokers. 

I sat across from a young woman last month who couldn’t have been more than 24, who told me she was thinking about leaving engineering. She was brilliant, Technical, sharp, and thoughtful.

But somewhere between her entry into the tech sector and her early days, someone made her feel like she didn’t belong there.

I recognized that feeling immediately.

Because I started as an engineer, too. Back when that world wasn’t exactly rolling out the welcome mat for women. I remember the meetings where my ideas landed differently when I said them versus when a male colleague presented something similar.

I remember the networking events where I was often the only woman in the room, and not in a powerful way, but in a way that made you hyperaware of every word you said. I remember thinking, more than once, that maybe this wasn’t built for people like me.

But here’s what changed everything: I found my tribe.

Not everyone discouraged me. Yes, there were voices that questioned whether women belonged in STEM, voices that made the path steeper than it needed to be.

But there were also people who were thoughtful and cooperative, who believed differently. Who saw my work, not my gender. Who invited me into conversations, opened doors I didn’t even know existed, and most importantly, treated me like I belonged there.

That support wasn’t loud. It was quiet, consistent, and reassuring.

These people became more than just colleagues. They became my tribe.

The kind of people who knew my strengths before I fully believed in them myself.

They pushed back on the assumptions in the room. They made space for different perspectives. They built something I didn’t see coming: they built the evidence that a woman’s voice mattered in engineering.

What I didn’t realize then was that I was learning something far more valuable than any technical skill.

I was learning what it looked like when someone believed in you enough to create space for you. I was learning how support actually works, not through grand gestures, but through small, consistent choices. Through showing up. Through believing first, and letting their belief become your foundation until you could build your own.

Years into building my career, I realized something: the crack in the system, the place where the assumption that women aren’t suited for STEM lives, wasn’t something to accept. It was somewhere I could shine my light.

I started asking myself a question: What if I became the person for someone else that my tribe had been for me?

What if every woman I met who was thinking about leaving or maybe doesn’t feel like she belongs here didn’t have to feel alone in that decision?

That’s when CodeGirls began.

CodeGirls is a project close to my heart, a place where young women can learn real, industry-ready tech skills that will help them in their careers.

It’s a transformative women’s empowerment initiative that equips young women with industry-ready coding and business skills to help them build careers and achieve financial independence. Since its inception, CodeGirls has delivered 2,000+ trainings, achieved a 70% placement rate, and helped graduates reach an average monthly salary of 55K+, with its work spanning Karachi, Skardu, and South Africa.

And alongside that, something even more essential: a community that believed they belonged there from day one.

Because here’s what I know now: the missing piece was never whether women could code.

Women can code.

Women have always been able to code.

The missing piece was the tribe.

The people around you who make space for your growth. Who see your potential before you’re finished. Who believe in you when the system doesn’t.

Through CodeGirls, we’ve watched this transformation happen over and over. We’ve seen women come in uncertain, often having been told by culture, by family, by the world that this path wasn’t for them. And then they work anyway. They build. They lead. They are breaking the stereotypes and proving most men wrong about women’s inclusion in tech.

I think about that 24-year-old woman across from me, and I think about thousands like her. Every time a young woman decides not to leave engineering because she found her people, that’s everything.

Every time a woman realizes that belonging isn’t something she needs to earn but something she gets to build with others, that changes the trajectory of her entire life.

The system hasn’t changed overnight. There are still cracks, still assumptions, still voices that question whether women belong in spaces built for technical thinking and leadership. But what has changed is this: more of us now know better. Who know what it feels like to be believed in.

Who are determined to be that belief for someone else.

Networking isn’t about collecting business cards or climbing the right ladder. Real networking is about finding your tribe. The people who see you. The ones who make space. The ones who believe in you enough to pull you into conversations you didn’t know existed.

And once you find them, the next step is simple but profound: become that person for someone else.

That’s the work CodeGirls does. That’s the work we’re committed to at Genetech Solutions, too.

That’s the work that happens every time a woman who made it decides to open the door for another woman who’s just beginning.

The cracks in the system are also the places where light gets in. I hope you can benefit from my learnings.

I’d love to hear about your experience when you started, struggles you encountered, the mentors who believed in you, the tribes you’re building, the spaces you’re creating, and the doors you’re opening.

And if you’re looking for a way to open a door for another woman, consider sponsoring a CodeGirl. Your support helps a young woman gain industry-ready tech skills and move toward a career in the technology industry.

You can also hire a CodeGirl and give a talented woman the opportunity to put her skills to work in the industry.

If you’d like to chat about how we can support more women in tech and entrepreneurship, I’d be glad to help.

If you made it this far, we’re probably thinking about the same things. Follow me on Medium so you don’t miss what comes next: medium.com/@shamim_rajani

Seong, M., Kim, H. G., Yun, B., Kim, M., Kim, J.-W., Jeong, H., Kim, S., Kim, J. H., & Cho, K. H. (2026). Hybrid deep learning-numerical modeling framework for long-term prediction of groundwater discharge and radionuclide transport. Journal of Hazardous Materials, 504, 141346. doi.org/10.1016/j.jhazmat.2026.141346

“The model was trained to predict monthly groundwater discharge (GWD) and radionuclide transport (RNT), and its performance was evaluated against the results from HGS, which serves as a physically rigorous reference model.”

“Because real-world data for the hypothetical ADioS watershed were unavailable, the HGS model, which is a fully distributed, physically based, integrated surface–subsurface hydrological model, was used to simulate groundwater flow and radionuclide transport for target feature extraction.”

Graphical Abstract

We're pleased to highlight this publication by Minkyeong Seong and colleagues, which presents a hybrid deep learning–numerical modelling framework for improving long-term predictions of groundwater discharge and radionuclide transport. Using HydroGeoSphere (HGS) as the physics-based reference model, the researchers combined process-based numerical modelling with a graph convolutional long short-term memory (GC-LSTM) deep learning model to produce long-term predictions while dramatically reducing computational costs.

Long-term prediction of groundwater flow and radionuclide transport is essential for evaluating the safety of deep geological repositories used to store radioactive waste. While fully integrated numerical models such as HydroGeoSphere provide highly accurate simulations of coupled surface water, groundwater, and contaminant transport processes, these simulations can become computationally demanding for assessments spanning decades, centuries, millenia or even millions of years. Simpler models offer faster runtimes but often sacrifice accuracy by neglecting important processes such as unsaturated flow. This study addresses that challenge by combining the strengths of physics-based modelling with artificial intelligence to improve both efficiency and predictive performance.

Fig 1. Overview of the hybrid modeling framework: (1) data preprocessing from two numerical models: adaptive process-based total system performance assessment framework (APro-BIO) and HydroGeoSphere (HGS); (2) graph construction for the graph construction for the graph convolutional long short-term memory (GC-LSTM) model; (3) model development for predicting groundwater discharge (GWD) and radionuclide transport (RNT); (4) model training and eval uation; and (5) model interpretation using GNNExplainer.

The researchers developed a hybrid modelling framework using outputs from the Adaptive Process-Based Total System Performance Assessment Framework (APro-BIO), together with HydroGeoSphere simulations, to train a graph convolutional long short-term memory (GC-LSTM) model. HydroGeoSphere served as the benchmark model by generating groundwater discharge and radionuclide transport data that the deep learning model learned to reproduce. By incorporating hydrologic variables alongside key unsaturated soil properties, including van Genuchten parameters, the GC-LSTM captured the complex spatial and temporal interactions governing groundwater flow and contaminant transport throughout a hypothetical watershed representing a deep geological disposal system.

The hybrid framework demonstrated strong predictive performance, achieving Kling-Gupta Efficiency (KGE) values ranging from 0.67–0.85 for groundwater discharge and 0.60–0.81 for radionuclide transport. Compared to the simplified APro-BIO model, the GC-LSTM reduced discrepancies with HydroGeoSphere by up to 99%, closely reproducing both the timing and magnitude of groundwater discharge and radionuclide transport across the watershed. Once trained, the deep learning model generated predictions in less than one minute, providing more than a 3,000-fold improvement in inference speed compared to running new HydroGeoSphere simulations while maintaining excellent agreement with the physics-based model.

HydroGeoSphere played a central role in this research by providing the physically rigorous benchmark required to train and validate the hybrid modelling framework. Its fully integrated simulation of saturated and unsaturated groundwater flow, surface water interactions, and radionuclide transport enabled the researchers to accurately represent complex hydrologic processes that simplified models cannot capture. HydroGeoSphere also demonstrated the importance of unsaturated zone processes, showing that accounting for soil hydraulic properties significantly improves predictions of groundwater recharge, groundwater discharge, and radionuclide migration.

This research demonstrates how HydroGeoSphere can serve as the foundation for next-generation hybrid modelling approaches that combine physics-based simulations with artificial intelligence. By leveraging HGS to generate high-quality training data, the researchers developed a framework capable of maintaining the accuracy of fully integrated hydrologic modelling while dramatically reducing computational costs. The approach offers significant potential for long-term groundwater safety assessments, radionuclide transport studies, and other computationally intensive environmental modelling applications where both speed and reliability are essential.

Abstract:

Accurate long-term prediction of groundwater flow and radionuclide transport is critical for assessing the safety of deep geological disposal systems. This study proposes a hybrid modeling framework that integrates a numerical model with a deep learning approach to improve the predictive accuracy and computational efficiency. Outputs from the adaptive process-based total system performance assessment framework (APro-BIO) model, including water level, surface water flow, groundwater recharge, groundwater discharge (GWD), groundwater flow velocity, groundwater level, and radionuclide transport (RNT), together with van Genuchten parameters, were used as input features. Monthly groundwater discharge and radionuclide transport simulated by HydroGeoSphere (HGS) served as target variables, and a graph convolutional long short-term memory (GC-LSTM) model was trained to capture spatial and temporal dependencies. Model performance was evaluated against that of HGS, representing coupled saturated–unsaturated flow. The GC-LSTM achieved Kling–Gupta Efficiency values of 0.67–0.85 for GWD and 0.60–0.81 for RNT and reduced discrepancies relative to that of APro-BIO by up to 99 %. The model effectively reproduced temporal variability while reducing computational cost. Explainable AI analysis identified the van Genuchten β parameter as the most influential feature. These results demonstrate that the proposed framework provides an efficient and reliable alternative for long-term GWD and RNT prediction under computational constraints.

The post Fall PD day camps appeared first on Grand River Rocks Climbing Gym.

First of all is it fair to call a compulsive, pathological thief by any such name each and every time they walk into a store? Is it fair to call CRA/GHD intellectual prostitutes each and every time they write an alleged scientific report. I described here a little bit about their latest (Sept. 3, 2026) effort titled "Bench Scale Study for Biodegradation of Chlorobenzene and NDMA" yesterday.  

I have confirmed with a past APTE coordinator that we had all been told decades ago by Uniroyal Chemical and their consultants that chlorinated solvents such as trichloroethylene, chloroform, chlorobenzene etc. do not easily degrade or break down on their own in soils. It turns out however that chlorobenzene is the exception to that rule. Now according to this latest report by GHD, chlorobenzene actually degrades very well on its' own in shallower, aerated soils and less so in deeper anaerobic soils as per pages 7 & 8. The Figures section, particularly Figures 1 and 5 also confirms this. This of course speaks very badly of Uniroyal and CRA because the inaccurate information was used to deny chlorobenzene's presence on the Varnicolor Chemical site when zero chlorobenzene was found in Varnicolor's shallow aquifer also known as the Surficial Aquifer (SA).  

Other problems exist including the premature thawing of frozen groundwater samples meant to be used in the Bench Scale Biodegradation Study. While I appreciate the admission of this unfortunate incident that occurred at U.S. customs I am less comfortable with GHD proceeding with their experiments using compromised groundwater samples rather than starting over. Another problem might be GHD's repeatedly advising that their Biodegradation Rates may very well be biased on the high side due to possible volatilization of compounds from the groundwater samples. I wonder if this so called volatilization didn't occur and they spiked the samples according to page 3 with 150 ppb. chlorobenzene and 2.4 ppb. NDMA, if their Biodegradation rates might actually be biased on the high side. Either way again I find their protocols surprising and disturbing. It seems to be a vey peculiar way to be conducting scientific experiments. It's almost seems to be a "seat of the pants" scientific protocol. Something goes wrong so instead of really fixing it or starting over they just make a change and continue on.

Assuming for the moment that their experiments have some validity what I conclude is that dissolved chlorobenzene degrades in both aerobic (oxygen) and anaerobic (low oxygen) environments. NDMA on the other hand seems much less capable of degrading via human intervention such as amendments and nutrients both in shallow and deeper soils. Of course as mentioned yesterday chlorobenzene has other characteristics and the issue is not what the dissolved chlorobenzene will do as much as what the Dense Non Aqueous Phase Liquid (DNAPL) chlorobenzene will do. The "Non Aqueous Phase" part of that acronym makes it clear that DNAPLS are NOT dissolved in water chlorobenzene but thicker, heavier pools or puddles probably residing in depressions of lesser permeable soils such as silts and clays. Likely some of these have dissolved over the last thirty years but any claims by Lanxess and fellow travellors that they are fully dissolved is nonsense, wishful thinking and maybe even intellectual prostitution. 

It allegedly took GHD a year from sampling groundwater to releasing their modest 34 page report titled "Bench Scale Study for Biodegradation of Chlorobenzene and NDMA". Actually from when the project was first proposed to TRAC (Sept. 2024) it took two years although of course our beloved and  besmirched MECP had to take a look at it first. What shocked me the most was the somewhat belated 37 YEARS that it took GHD or the MECP to advise citizens that chlorobenzene degrades so rapidly in shallow soils and at ground surface. I knew that it would volatolize (evaporate sort of) in the air as so many solvents do but it was only a week ago that I understood why chlorobenzene had allegedly never been found on the Varnicolor Chemical site in their Surficial Aquifer (SA) wells. It was not as I've long suspected that the Ontario Ministry of Environment actually fudged the results either by switching samples or by ordering their labs to improperly mark the results as Non Detect. It was due to the very rapid degradation of chlorobenzene by shallow soil bacteria in a well oxygenated (aerated) environment. This by the way is unusual and we were long told by Uniroyal/Crompton/Chemtura/CRA that chlorinated solvents do not degrade well by soil bacteria due to the tight chlorine bond combined with chlorine being a known bactericide (antiseptic if you will)   Now as we all know here in Elmira chlorobenzene has persisted for a very long time in our deeper aquifers and continues to do so well in excess of the Ontario Drinking Water Standards (ODWS).

 There likely is something else going on however as this study also claims on page 8 that chlorobenzene degrades under anaerobic (low oxygen) conditions. Indeed their Figures section seems to confirm that. If chlorobenzene degrades naturally on its own then why has nearly thirty years of pumping and treating not done the job? The answer is simple and this Susan Bryant is for you. It's called DNAPLS as I and Rich Clausi told  Sylvia Berg and the APTE co-ordinators in January 1994. Esther Thur, one of the three founders of APTE (Sandra Bray, Susan RUPERT, Esther Thur), knew the truth when she heard it but the others unfortunately relied on Sylvia. Chlorobenzene DNAPLS both on and off the former Uniroyal Chemical site are doing what DNAPLS do which is slowly dissolve into groundwater at greater than the ODWS and will continue to do so likely for decades and maybe much longer. 

This past Monday and Tuesday (Aug. 31 & Sept. 1/26)  I informed this Blog's readers plus about sixty other authorities (MECP, TRAC, Lanxess, Woolwich Twn., RMOW etc.)  and citizens that chlorobenzene   rapidly degraded in shallow soils. Lo and behold TWO DAYS LATER (last evening) I get the e-mail report from GHD explaining attempts to enhance degradation of NDMA and chlorobenzene combined with the data all citizens should have had decades ago about chlorobenzenes rapid natural degradation. Coincidence? If so an absolutely amazing one.
