4 days of data compared to my billed amount from the power company. I believe the difference in measured vs billed is because of my power company not wanting to overcharge customers. If you add up the 4 days the data reads:Power Company Consumption charged = 79.64 and measured = 76.98Power Company Generation credited = 69.92 and measured = 70.32The Consumption I am charged is consistently at -4% of what I measure and the amount they credit me is less than .5% over. So, this meter appears to be very accurate and consistent. I do wish there was a way to adjust the calibration so that I could get closer to what my power company is charging and crediting me for. But this does what I want and gives me a Realtime idea of what is going on with my electricity and solar production.I only have 2 phase power with the 2 large clamps on then 8 small clamps on my solar breakers. I am only concerned with Power to and from the Utility and how much Solar I produce each day. This meter works very well for my purpose. Even though I don’t have the individual circuits on my loads it tells me how much my house is using based on the large clamps vs the smaller clamps production. This is an inexpensive product that gives you a good idea of what is going on with your Electric circuit’s. Works very well with Tuya.Cost Function is basically useless as you can only put a whole number in the rate for electricity. If the developers read this, please put a decimal place in the electricity rate. Also maybe add a way to put in different "time of use” or TOU rates. I don't know what Fit rate is supposed to be for.

Very easy to install. Super simple to wire up and get running in under half an hour. Links with any Tuya/SmartLife compatible app so it may also pull in to Alexa and Home Assistant if you use the proper integrations (I have not tested however). You have the option to install it inside the breaker box (if you have room) and then run the antenna out for best reception or you can mount the entire unit outside of the breaker box and simply wire the sensors thru an access to the panel. I had just enough room in the box for everything and there was already a punchout on the side that worked out perfectly for threading the antenna to wall mount it. Get an electrician to install this for you if you have even the slightest hesitation about it being a DIY. They can get it done in perhaps 15 minutes or less so it would not cost an arm and a leg. Sensor values are very accurate and thus far the readings are pretty close to the "live" reading from our power company's smart meter. One thing I can say is it is already saving me money after just a week - the ability to see each circuit is a fantastic way to find all that wasted power usage - it is crazy to see how many devices have a massive vampire draw even when turned off and how inefficient certain appliances are.

This does monitor the energy useage. It has a great chart too but it needs improvement. You can only observe the total for each hour and not what used each amount of electricity.You can certainly see who h circuit is using the most right now, just not past usage.Aggravating enough, the install was difficult. The leafs frequently had to be pulled out and put back in. It took me five tries to get the box to see all 16 circuits.

The energy monitor system is a neat idea. I haven’t installed it just yet, but I personally won’t have any problem with doing it. The only part of the installation that would give me pause is attaching the big clamp meter to the mains coming into the box, as it’s always going to be live, even when the main breaker is off. The other smaller (sub) clamps along with the power for the main unit can safely be installed with the main breaker off, since everything but the mains input has the power cut when the main breaker is off.Everything else is set up on the app, Smart Home (also Tuya).This is really a cool device, and should be no problem for an electrician to install if you have some pause with installing it yourself.Should the installation not go smoothly, or there’s some other issues, I will update it here. Otherwise, it’s recommended.

It's much less expensive than other kits and very easy to install considering you just clamp the sensors around the existing cords. I didn't even have to turn off any circuits during install because I had some free breakers to power the unit that were already plugged in.Connecting was easy, I already have the smart life app for some other tuya devices and the app recognized the device and added it in seconds.The data is very basic, you can see real time usage of every circuit, and you can see a chart of overall historical usage broken down by week or day. Unfortunately you can't see the same chart for a specific circuit, only the percentage of overall usage that each circuit used. That's broadly what I want to monitor, but it would be nice to see if a particular circuit had been spiking or otherwise behaving unexpectedly, which you can't do without watching in real time.It updates fairly infrequently (maybe every 30 sec) and is a little finicky. Sometimes the app claims it's made too many requests and has to wait for new data. I have one circuit that sometimes just reads 0 amps when I can see that the large appliance the circuit runs is currently on. I have the hub installed outside the box with clear line of site to the router and the overall connection doesn't seem to waver, so this appears to be just a problem with one of the individual sensors.Most of the others work and the numbers coming out of them are reasonable and believable so I'm still getting some decent utility out of it.

Integration with Tuya's SmartLife app ecosystem means that this also works decently in HomeAssistant, allowing for solar or appliance energy use integration. It'd be great if the cost for just two clamps were a little less, given that the 8-16 count CT sets aren't that much more expensive.
