Shelly 1PM Mini Gen4

Matter pairing was effortless with my phone, and the Bluetooth fallback means I can still adjust it when Wi-Fi drops. The relay clicks solidly and the power monitoring is spot-on for tracking my radiator's usage.

Installed this in the junction box behind my wall switch and the size made it a breeze to fit. The power monitoring in the app is accurate down to the watt, which I've confirmed with my own meter, and having both WiFi and Bluetooth as fallback is a nice safety net.

The Matter pairing worked flawlessly on my first try, which never happens with smart home gear. The built-in power monitoring is surprisingly precise too, so I can finally see exactly what my old fridge is pulling each day.
