I have just installed Aeotec’s Home Energy Meter (Gen 5) to monitor power usage. I’ve installed it correctly and used the default SmartThings handler that ST selected. However it is overreading by about 120 watts. I’ve proved this by comparing power usage readings on the actual electric meter and against a (non-smart) power meter (that I am hoping to replace).
Has anyone come across this before? I expect it’s something to do with the wrong voltage being configured in the ST default handler, but can’t see any way of changing this.
I did look for a custom device handler, but struggled to find anything that seemed stable.
