The Shelly Plus 2PM. It switches two independent channels, measures energy on each, adds overvoltage, overcurrent and overpower protection and carries a 3-year warranty against 1 year. The Switchbot Relay Switch 1 wins on price and smart home integrations.
The Shelly Plus 2PM has an interlock mode for exactly that, driving the up and down motor lines of shutters, blinds or gates with its two channels. The Switchbot Relay Switch 1 has a single channel and no interlock mode.
The Switchbot Relay Switch 1 supports both, alongside Alexa, Google Home, SmartThings and Home Assistant. The Shelly Plus 2PM works with Alexa, Google Home, SmartThings and Home Assistant but not with Apple Home or Matter.
The Switchbot Relay Switch 1 is rated at 16A for resistive loads on its one channel, while the Shelly Plus 2PM is rated at 10A per channel. Both also support DC loads up to 10A.
Anyone automating shutters or two circuits from one switch box who wants energy data per channel, comprehensive electrical protection and a long warranty.
Buyers who need one switched circuit on a smaller budget and want it in Apple Home or a Matter setup, with power-off memory and a wireless switch mode.
