we used this to monitor energy usage on two new heat pumps. Easy to install and set up.

easy to connect to wyfi and works great to see how much i am truly pulling when the RV is hooked up.

I put this in to monitor energy consumption on a heater. The device will not stay connected to the WiFi and has to be rebooted every day or so. No data will be stored if its not connected. The software to view the data stores it in a way I cant make heads or tails of what its doing. This heater is either on or off, but the meter shows my power being used at different levels at different times. In this situation, that is impossible. I wish I had put it in soon enough that I could return it still. Maybe I got a bad one. I wont be buying a second one.

I use this to monitor the energy usage of my HVAC and tankless hot water unit. Does its job pretty well but if connectivity is lost, instead of returning the missing data, it clumps it all in the hour connectivity was restored.I would like to be able to see graphical minute-by-minute usage in addition to hourly and daily.It's unclear if it can be powered by a 240V circuit. I'm using a lamp cord and have it plugged into an outlet. That works well but the energy reported is half of its real value.The Tuya app seems to work well and I have other devices being controlled by it.The CTs supplied did not have an directional arrow on them so they required needed to swapped to get the right values.

First photo. Can not read the current or power in each circuit.Second photo. Vertical co-or not identified.These units appear to be for the British 240 system. On US single phase 240ac systems they don’t measure current accurately. Seems to be off in the high direction. It does not compute on solar system with two circuits . Reads one ckt. As forward energy and the other as generation. When you add the two for total energy it reads high.

I would have given a five-star rating but I only gave it four stars because the app is a little bit lacking in information that would have liked to have seen. Mainly, it would be great if they could add the functionality to put in your billing dates or pick the date range you'd like to see usage for so that the report can be matched against the electric bill. As it is now, it's done by day week and calendar month which doesn't coincide with the electric bill. I don't know if the other monitors out there allow you to set a custom range or not but this one doesn't.The company's customer service was excellent. I had ordered the 80 amp monitor but the coils were a little too small. I reached out to the company to ask if they had the larger current transformers. They did but said they didn't advertise them on Amazon. I asked them if I could purchase the larger coils for this unit, and they sent me the replacement coils free of charge! It took a few weeks for them to get here, but I was happy to hear they were replacing them at no charge considering that there was nothing wrong with the coils I had, they just didn't quite fit around the wire. The coils that came with the monitor had the right size opening when compared to the size of the wire, but the wire wasn't a completely round shape and so they didn't snap around it completely.As to the functionality, I compared the readings from the monitor against the electric company's meter, and it is more accurate than I expected. The readings were only off by a few kilowatt hours which is negligible as it still provides an almost exact estimate of my energy usage.Overall, I'm happy with both the monitor and the customer service!

I used this device for 2 solar panels i added.They read power generation in Amps and keep track in Smart Life App in kWh for the day, week, year is max. Pairing was very easy, just power it up and scan in the App. If you want to delete the historical data then choose edit in the app inside the device itself. Select Remove Device, it will then ask if you want to disconnect or disconnect and wipe data. Simply unplug it the power it up again.Scan in the app for new device, add it. It does not come with a power cord, so I cut an old 2 prong extension cord to use. It is mounted in a breaker box outside on a brick wall on the other side of the house furthest point away from my wifi router and it picks up wifi no problem. Extremely happy with this. Just bought the next size up so I can read my total produced and my total used from the power company this will include my other 18 solar roof panels. I purchased this one to monitor the production of the 2 newly added panels only, in case one of the panels or a microinverter goes out too.

This is a great value, but it requires an environment with continuous WiFi. I thought I could run it at a remote site with no Wifi and just check it occasionally with my cell as a Wifi hotspot, but it saves incremental energy usage in the cloud so without continuous Wifi it can create a energy use record. Not a problem for many or most use cases but not mine.
