Shelly Plus 1PM List

The power monitoring is spot-on—I can finally see exactly what my space heater draws in real time from my phone, and the 16A rating handles it without breaking a sweat. Setup in the app was painless, and the relay's been rock solid for two weeks straight.

It only took a few minutes to wire it inline with my water heater, and now I can finally see exactly how much electricity it pulls each day. The 16A rating handles the load without a hiccup, and the power metering data in the app is surprisingly accurate.

Installed this in my fuse box to monitor the water heater and the 16A rating gives me plenty of headroom. The power consumption data updates fast in the app, which is perfect for seeing exactly what that thing costs to run each month.
