EMPORIA ENERGY Smart Home Monitor with 16 50A Circuit Level Sensors | Real Time Electricity Monitor/Meter | Solar/Net Metering

Great product, easy to install and just works. Regular updates. Highly recommend.

I like everything about this product and I enjoy using it; - Very easy to install, see Pics - Solid WiFi connection - Good instructions - App is very responsive, no failures or glitches - Almost real-time, very impressive - Flawless CSV downloads - Alerts work well Actual benefits; - able to identify a total of 142W of phantom load = ~$180 CAD/yr for a payback of ~1.5 years - able to quantify the max hot tub load @ -22C (1,225W) and move the deicing cable from a lighting circuit to the dedicated 120V hot tub circuit, so now it is monitored - able to demonstrate that our new hyper-efficient gas furnace is consuming an average 62W more than the previous unit, so I have engaged the vendor to determine why - identified the the top consumers, not sure what I can do about it yet, but at least I know now Couple of points; - will need to use 2 CTs on 240V circuits for accurate measurement, e.g. a dryer motor only uses one of the phases, so if you use one CT and double the multiplier the results will be inaccurate. I moved a CT so now both phases are monitored - I had to mount the unit inside the panel to reach the mains. Two 16 sensor units would not fit inside a typical fully loaded panel, however I could mount them externally by using one unit on the left side and one on the right side. I have 42 active circuits but only 15 are monitored so another unit would significantly reduce if not eliminate the balance of 31% - I spent an entire day tracing all the circuits so I knew where to best allocate the 16 CTs, and I now have a detailed map - I download a CSVs weekly and archive them as they are very small ZIP files - I look forward to future App/backend enhancements WELL DONE Emporia!! Update 2022-11-27 - It's been about ~11 months now and this product has worked flawlessly, this has got to be one of the best products I've ever purchased. I expected some glitches and idiosyncrasies but to my surprise, it always works, it is fun to use and quite informative. For example, I didn't expect that our hot tub is by far the largest individual consumer @ ~14% after 11 months or ~$215 CAD/yr and we only use it during the summer although it runs all year. That is really surprising given that it is a small tub connected to a 120V circuit. The "Balance" @ ~22% includes all devices on all circuits that are not monitored. Update 2025-01-07 - It been a touch over 4 years now, and everything is working great. I have moved a couple of CTs and bought a 4 pack of the smart plugs, which also work very well, but are limited to a continuous 400W. I recently moved the controller outside the panel to reduce congestion and so it is more accessible. Ideally, I would prefer to install all components outside the panel, properly tagged of course, but that is very installation specific.

Purchased this to monitor our Barn Sub-Panel, a recent addition to the house. It's a 1500sq/ft building with two 18k BTU mini spits, 800w of LED overhead lights, 2 post lift, full wood shop, welding outlet, etc. There's eight 240v circuits and eight120v circuits in the subpanel this was installed in. Install was straight forward, but if you're not comfortable working in an electrical panel, I'd recommend letting a licensed electrician do it. I wired the subpanel and the barn, but am not a licensed electrician, it's all inspected Rough and Final, but different jurisdictions have different rules about is legally allowed to do electrical work on their home. On to the review - Well, it definitely muddies up a clean electrical panel with the sensors and their wires but it's not too bad. If your panel has a TON of excess wire and is very full, this is going to be a tough installation. Once installed the set up is pretty straight forward and the instructions to do so work well. For each 240v circuit (two 120v legs) only one sensor is needed and the software in the app can be set to multiply the value by two; this in principal works great on things like Mini splits or a dust collector for example. However some 240v devices will have 120v items that will run between one of the 120v legs and a neutral wire, so if it's monitoring the leg being used for that 120v item, it's going to double it's usage and if it's monitoring the other leg, it won't measure the usage. This isn't that big of a problem, the 120v items on these types of circuits are hour meters or small control boards, etc. but it can create some inconsistencies. The view of everything is eye opening and that's why I'm not sure I love it.... but I do. It's very helpful to know what things cost. For example the network (security cameras, network switch, wireless AP's and related) are operating at able 2kw/hr's a day (a little less than a normal 80w systained draw. For me, it's $0.32/day to run the Barn's network. HVAC usage as well being able to see it is helpful to know if it's worth the cost to keep the barn warm or just warm it up when I use it. Overall, I'd definitely recommend this, it's price point over other brands is a bonus. Since purchasing this, we've also added four of the US Smart plugs from emporia that do the energy monitoring and are just as happy with them. We'll likely be adding two additional 16 circuit monitors to our two existing 200a service entrance panels.

Having just dropped a sizeable chunk of our savings on 8.5kW of solar PV and a Tesla Powerwall, we've gotten very conscious of energy use in our home. I wanted a way to measure individual circuit consumption, and after trawling the internet, looking at the technologies and reading reviews, I decided that the Emporia Vue 2 was probably the best bet. Firstly, it's very accurate, as in +/- 1% accuracy from my experience so far. Being mains powered rather than battery powered, the unit can reference the measured circuit phase angle to give very accurate power consumption. Secondly, it's easy to install and setup, though UK consumer units pose certain challenges. More on that later... Thirdly, the App is really well thought out, easy to use, provides a phenomenal level of granularity and is easy to export .CSV data to manipulate in Excel for instance. The level of detail available will easily satisfy even the nerdiest of nerds! Rather than install the first unit in the house, I opted to install it in my garden Office/Workshop/ManCave so that I could tinker around, figure out how it all works and determine the best way to fit it without disrupting the main house supply. SWMBO works long hours from home, much of the time on conference calls, so killing the power/internet/network regularly whilst tinkering wasn't a viable option. The biggest challenge I had is that UK consumer units just don't have much free space in them. Just getting the sensors in there is a fairly tight fit. Trying to shoe-horn the excess sensor cabling, the unit itself and the wi-fi cable into my CU was impossible, so I had to get a little creative. In the end, I opted to mount the unit externally to the CU. I used one of the bottom, 20mm knock-outs, drilled it out to ~23mm and fitted a PG16 gland, which was just big enough to fiddle the (5) sensor plugs and power cables through. I also snipped the heatshrink off the WiFi lead and unscrewed the antenna from the cable, then fitted the antenna directly to the main unit. The unit has no wall mounts, so a few adhesive velcro pads hold it in place. One item the instructions don't cover is UK final ring circuits (ring mains). Reading between the lines in the instructions, you'd think that clamping 1 wire and using a 2.0 X multiplier would be the correct approach, right? Wrong. Ring circuits rarely balance properly. It depends very much on the circuit load and how close it is to one end of the ring vs the other. The right approach is to clamp both wires and use a 1.0 X multiplier. CT sensors measure Total current passing through the sensor, so will measure the sum of the current passing through each wire. Fitting this way gives much more accurate readings. The unit is really easy to configure. Connecting to WiFi is easy and the App is very intuitive. If you want to properly monitor power consumption in your home then this is by far the best option on the market.
