Review on 🏡 Sonoff Assistant with Monitoring Support: Enhanced Compatibility for Smart Home by Rudy Santos

Advantages: Small area, so you can install two on a normal single socket. Appears to be well put together, a cut above the unnamed material of dubious provenance and attention to the electrics. Code/Security. It is EXTREMELY easy to disassemble and flash the Tasmota/ESPHome when you need it. Easily integrates with Home Assistant and displays history of energy consumption, power, apparent power, reactive power, power factor, voltage and current. Cons: I ordered five units; (four S31s and one S31 Lite) in the last two months, and only one in five (S31 Lite) had the UL Listed badge. (The design and components of my S31 PCB look identical to the UL listed version pictures posted online so I'm not worried about the component/build quality but the UL certification will make this a 5 star Make Product.) Form Factor Blocking adjacent outlets when used with a regular power strip/surge protector/UPS. In this case, 1-foot mini extensions will help.
