Shelly 2PM Gen4 vs Shelly Plus 2PM

Full Smart Relays comparison in 2026

Updated November 2026
Data from the official Shelly site.
2026 verdict
The newer generation earns the upgrade: the Shelly 2PM Gen4 is the better dual-channel smart relay, adding Matter and Apple HomeKit support that the Shelly Plus 2PM lacks, and it can run on Zigbee and act as a Zigbee router.

The Shelly Plus 2PM remains the more affordable choice and documents things the Gen4 spec sheet does not yet confirm, namely DC power input and both dry and wet contact modes. Otherwise they match closely: two channels, per-channel energy monitoring, interlock mode for covers, overheating, overvoltage, overcurrent and overpower protection, and a 3-year warranty. Apple Home and Matter users should buy the Gen4; a Home Assistant or Alexa setup on a tighter budget is well served by the Plus.
