Eyedro Home Energy Monitor – Real-Time Electricity Usage Monitor with Solar Net Metering – Whole House Power Consumption Monitor – WiFi/Ethernet Smart Energy Meter with Reports & History, 2 Sensors

We’re using this in a nonprofit setting to sub-meter a separate building, and it has worked perfectly for that purpose. Installation was straightforward, and once configured, it immediately began providing clear, real-time electricity usage data. The readings have been consistent and reliable, which is critical when the data is being used for billing and accountability rather than just general monitoring. What really makes this system valuable for us is how it integrates into our reporting process. We’ve automated a monthly usage report that is distributed simultaneously to both the renter and the building owner, making the payment process transparent and straightforward. Having accurate, real-time data feeding that report eliminates guesswork and avoids disputes. While it supports solar net metering, we’re strictly using it for sub-metering and cost allocation, and it performs exceptionally well in that role. For organizations needing dependable energy tracking with practical reporting applications, this has been an excellent solution.

I purchased this a week ago, and installed it literally in a few minutes. I did not even look at the directions, it's just too simple. The install is really easy if you're at all handy and not afraid of your load panel. Simply put, you remove the cover from your load panel, open the sensor by pushing in the little clip, slide the sensor around one of the power mains, and clip it shut. Repeat for the other sensor. Drop the wires out of the panel and replace the cover. Then connect the sensors to the EyeDro box, run an ethernet cable to it, and plug in the power. Voila! Next, go to their website and register an account, and either enter the serial number from the box or click the "Scan network" option which will find it. That's it, you're up and running! The box itself is very small, about the size of a deck of cards. There are no indicator lights on it, but it does include screws and a mounting template if you want to wall mount it. If you have not decided yet, you can go to their website and play with a demo version of the system, which is nice. It has the following reports: * Highlights. This shows a bar chart with recent power usage per hour, a meter that shows current usage (and is very responsive), today's total usage, today's projected total usage, a comparison to last month, the minimum and maximum amount of power used, the current rate (if you entered it into the setup, such as a tiered rate like I have), your estimated bill to date, and an estimate for your total bill. The best part about the Highlights is that the meter is VERY RESPONSIVE. I can watch the needle move up and down in near real-time. I can see when the stove is turned on, then watch as it cycles the burner on/off to maintain heat. It also shows a +/- designation that shows how much more/less power is being used presently compared to the last time the needle moved. For example, right now it shows -25w after a fan was turned off. If something else turns on, it would show +[number] to indicate the difference. * Insights. This shows your usage compared to other forms of power, such as gas, coal, natural gas, etc. I don't find this very useful. * Live. This shows a very detailed chart of minute-by-minute power usage. * Summary. This shows a bar chart with hourly totals of power usage. * Comparison. This shows a comparison of power used to the previous month on a daily basis. * Bills. This shows a 12 month billing history, daily cost, daily average cost, consumption per tier, and so forth. * Reports. This shows a weekly report of usage compared to previous weeks. * Phantom energy. This shows your minimum usage demand, and helps you track down low-use devices that cost you money while they are supposedly turned off. * What's it cost. This is a usage calculator that allows you to pick from a wide range of devices to determine how much they cost you to operate. * Net meter. If you have solar, or some other supplemental power supply system, this will tell you how much power you have generated versus how much you have used. The mobile website has all of these features as well, and has a really well done "swipe" design that allows you to swipe left/right across multiple screens per area. The site also has a variety of setup options, including a "rates" feature. This allows you to enter your rates from the power company, in one of three ways: * Fixed Price * Tiered * Time of Use You can also specify if you are billed: * Monthly * Bi-monthly * Quarterly Finally, you can also tell it that you have the following fees/charges: * Fixed fees * Variable (per kWh) fees * Adjustment factor * Taxes * Rebates My only complaints: You have to login to the website almost every time you visit, even if it's only been an hour or two. On the mobile site this often results in a box saying "error" and it never goes away, so you cannot login. You have to close the tab/browser, or restart your phone to get back in. (I have reported this issue to them as of 5/10/2015 so hopefully they will fix this.) It's just a little hassle to have to login each time. (SEE PHOTOS) In addition, the "Dial" meter is inconsistent. Some times it has the needle in the red zone for (example) 4 kWh, and then later it will have the 4 kWh in the yellow zone. It's not labelled either, and it should be. (SEE PHOTOS) All in all I really like it. This is exactly what I have been looking for, it's cheap, easy to use, and has really helped me understand what the energy hogs in my house are (hint: it's my HVAC). Finally, I got mine as an Amazon Warehouse Deal, for only $75! The box was very beat up, but the device was perfect and works great. Save yourself a few bucks if you can!

I bought this meter to monitor my power usage and determine what size of generator to buy for my house. For this purpose this device seems to be well suited and meets my needs. See lists below of specific items below related to my experience with this product. Pros: -Arrived fast -Easy to setup -Inexpensive compared to other options out there -Current transformers (CT's) unhinge so you can get them around the cables. -Phone app is handy and it is cool to see how much power your house uses at all times of the day -Included instructions were simple and easy to follow. -Information updates almost in realtime to the website which makes it possible to view the changing load as you turn devices on and off Cons: -Receiver unit only uploads the data directly with the Eyedro website through your internet connection, meaning if they company ever goes out of business or stops supporting this product then you can no longer use the product at all as there is no local readout or way to extract the metering data without accessing their website. (Note: Their website says they have been in business since 2009 so they have been around awhile and this may not be a big concern) -The data you can view, including the format, granularity, timescale, etc is limited on their website and there does not appear to be a way to customize it beyond the few standard options. EDIT: They have a feature on the web interface where you can export the data to a .CSV file which allows you to customize it beyond what is available on the website. This is useful to look at max, min and average usage over a longer timescale. -There are no Potential transformers (PT's) included with this kit, the units appear to calculate power consumption based on the current (Amps) the CT's sense and the voltage that you input for your system on their website during the initial setup process. This is fine as long as you realize the inherent limitations of this approach. Actual voltage and nominal voltage are not the same and actual voltage can vary throughout the day based on a variety of factors. If for example during the setup process you input your systems voltage as 120V but at a given time the actual voltage was say 109V or 130V this will effect the accuracy of your load calculations.

Fonctionne parfaitement

Bastante bueno he logrado identificar los aparatos que gastan más luz, identificando los gastos excesivos he logrado bajar 40% el consumo El precio se me hizo caro... pero ahora que se que es lo que gasta más luz he podido ahorrarla y ahí se pagará el costo de este equipo Me gustaría poder medir cada pastilla de luz pero solo hay esta versión que solo lee la principal

TLDR: It's a decent home/small-business solution. Gives a much better overview of energy consumption vs what KW Hydro has on their website. Good: - The version I have (2 measurement coils, wired internet connection) is affordable (<150$ on Amazon). - Easy to set up.Power consumption samples up to every 10 seconds. - Almost real-time (~5-10 seconds delay). - Handles correctly power and/or internet loss. - The web interface is reasonably easy to use and share with other people.Has enough advanced settings to be able to automatically estimate electricity bills and time-of-usage/tiered consumption. - The platform can be extended with add-on metering devices. Bad: - Requires an internet connection and the my.eyedro.com cloud to see any stats or download data. - Does not accurately account for voltage drop (since it does not have volt-meter) and power factor (mine is ~90%). So it will show a slightly higher load/consumption than what really occurred. You'll need to adjust this manually, so it's not a "set and forget" kind of setup. - Might not immediately sense subtle changes in load (10w or less), especially when in "change of state" polling mode. - To measure individual circuits (eg. solar net-metering, baseboard heating) one would need a much more expensive version of the device (that has extra measurement coils and ports) or to buy another meter just like this one (for each pair of circuits).

This product is really good but you need to have access to the electrical wiring you want monitored. I put mine on the two main wires feeding my electrical panel to determine what devices can be turned on when I run off a generator. I now see load all the time and can also see how much it costs. It can run with the included free cloud service or you can get instant demand from the built-in web server on the wifi version. Accuracy is as good as a current clamp can be and you can buy different amp rated versions of the current transformers. Distribution and warranty is in Canada which is a plus over others along with local web server. Very happy with the purchase. Once installed very easy to use, setting up TOU or Tiered calculation is tricky with HydroOne but the cloud service is very flexible. I can now also compare my hydro bill with what I measure myself.

One can install it yourself on the main feeds only if you are very comfortable with electricity. Otherwise it's best to have it done by an electrician. However you can use it for individual circuits as well. This is the entry level system and I have looked at expansion as I have an EV charge port. The idea was to potentially add a third measurement port for the charger. But the other systems seem exponentially more expensive. My charge habit is pretty straight forward and easily identifiable as can be seen in the night charge curve (midnight - 3 am). However if I would expand, I would just buy another EHEM1 unit. I don't have other systems to compare against, but find this system suits me well. Can recommend it to anyone who wants to get a handle on their electricity usage.
