Doesent work

App stopped working. There is no support. Basically wasted $250 for an energy meter that’s a brick without the software.

Kinda works

I love the idea of this and this app does give useful information. However, I find at least once a week often times more, the app bugs out and will double count some of my appliances kilowatt hour usage which basically makes whatever days data unusable cause I can’t trust it.
The days it’s right I have double checked with my energy provider and we are near spot on, but the days it bugs is infuriating. Also, it will sometimes randomly disconnect itself from the internet. Not sure if that is related to the data issues, but I’ve dig into it and I have no problems with any other device WiFi wise so looks like it is the hardware or software of this product.
