Great device and super easy setup. I did have some issues with the physical install but their support is awesome and responded very quickly and were able to help me get it sorted out. Just comparing the readings from this to what my power company reports it seems to be pretty accurate without any calibration, accurate enough for my needs at least. I highly recommend this device, a lot cheaper than the alternatives and you get more control over it, I’m using it with Home Assistant.
