Shelly 2PM Gen3

The power monitoring is dead-on accurate—I compared it against my utility meter and the readings matched within a fraction of a watt. It's been running flawlessly for three weeks now without a single disconnect, which is more than I can say for my old setup.

The Gen3 setup was a breeze, and having the power consumption data right on my phone has already changed how I use my appliances. The compact single-unit design fit neatly behind the switchboard without any hassle.

It handles two separate circuits at once, which is exactly what I needed for my water heater and AC. Setup was painless and the power readings in the app update fast enough to see my usage change in real time when something kicks on.
