When you want power monitoring only.

So glad they came out with a power monitoring only model, making it small and easy to fit in tight places. Works seamlessly with Home Assistant. Only con not Zigbee.

I cannot believe how tiny this thing is!

This device is just what I was looking for to track consumption of a toaster oven on a dedicated circuit. It's always plugged in so I don't need the switching capability.This thing is so tiny! It easily fit behind a GFCI outlet in a standard single gang box.Paired up with the app as soon as I turned on power and Home Assistant immediately recognized it once it was connected to Wifi.I've only had it a day, but so far I'm really impressed and totally happy.

Great product to send power. However has a week wifi signal, which drops the connection easily.

Worked like a charm to send data to Home Assistant. However due to the weak wifi adapter in this device the wifi connection may drop frequently or loose the connection completely. The PM device allows you to configure two wifi networks, one primary and one backup. The PM device will automatically switch between networks when required. When it does switch networks, the IP address of the device will change, which makes pulling data an issue. In order to resolve this issue, I configured the device to send the data to my MQTT server, which is accessible by both networks.

Good buy

These work great with my Home Assistant. Easy to get online and do the job. The reported power looks accurate when compared to manual volte and amp meters.

Working as expected, easy to install.

Just a week installed and it's working great tracking power to my furnace!I did opt to install it into an external plastic housing since installing it in the furnace electrical box would have shielded it with two very thick steel walls and I didn't think the WiFi signal would get out.Just keep that in mind when installing; WiFi doesn't like penetrating steel walls, steel ducting, and especially chicken wire!
