The Shelly Plus 1PM takes the overall win because of its complete protection set (overheating, overvoltage, overcurrent and overpower), its dry and wet contact modes and its DC switching. The Shelly 2PM Gen3 is cheaper, better rated and offers two channels, interlock mode and Matter and HomeKit support.
Channels versus contact flexibility. The Shelly 2PM Gen3 controls two circuits and can interlock them for a shutter motor. The Shelly Plus 1PM controls one, but it can isolate the relay with dry contacts and switch a 30V DC load, and it documents a full set of electrical protections.
Yes. The Shelly 2PM Gen3 meters each of its two channels separately, and the Shelly Plus 1PM meters its single channel, reporting power, voltage and total consumption. Either is a good way to find out what an appliance, heater or lighting circuit actually costs to run.
Only the Shelly 2PM Gen3, which supports Matter and Apple HomeKit as well as Alexa, Google Home and Home Assistant. The Shelly Plus 1PM has no Matter or HomeKit support and reaches those ecosystems only through Home Assistant or another bridge.
Buy the Shelly Plus 1PM if you want a single metered 16A channel with overheating, overvoltage, overcurrent and overpower protection, dry contact isolation for gates or boilers, optional DC switching and a 3-year warranty. It is the safer-specified module of the two.
Buy the Shelly 2PM Gen3 if you need two independent 16A channels, per-channel metering and interlock mode for a roller shutter, blind or gate, plus Matter and Apple HomeKit support. It is the cheaper module here and fits a standard back box with live and neutral.
