Then the Shelly Plus 2PM is the smart relay to buy, beating the Switchbot Relay Switch 1 on relay channels (two against one), per-channel energy monitoring, a full set of overheating, overvoltage, overcurrent and overpower protections, a 3-year warranty and stronger owner feedback. Its interlock mode also makes it a natural fit for blinds, covers and gates. The Switchbot Relay Switch 1 is the cheaper module and the more connected one, working with Apple Home and Matter on top of Alexa, Google Home, SmartThings and Home Assistant, and it adds a wireless switch mode, power-off memory and a higher 16A resistive rating on its single channel. Both run on 2.4GHz Wi-Fi, support dry and wet contacts and DC loads, and need a neutral wire. For shutters or two lights on one box, pick the Shelly Plus 2PM; for a single Matter-ready circuit on a budget, the Switchbot Relay Switch 1 does the job.
