Shelly 2PM Gen3 vs Shelly Plus 2PM

The Shelly Plus 2PM narrowly wins this pairing, thanks to a complete four-way safety suite, confirmed dry and wet contacts and a lower price. The Shelly 2PM Gen3 counters with Matter, Apple HomeKit through Matter and a higher current rating, so the right pick depends on which of those you need.

Ecosystem support and current. The Shelly 2PM Gen3 adds Matter and Apple HomeKit and is rated 16A, while the Shelly Plus 2PM is Wi-Fi only with no Matter and is rated 10A but adds a full safety suite. Both are two-channel relays with energy monitoring and a cover mode.

No. The Shelly Plus 2PM works over Wi-Fi with Alexa, Google Home, Samsung SmartThings and Home Assistant, but it does not support Matter or Apple HomeKit. The Shelly 2PM Gen3 adds Matter and Apple HomeKit through it.

The Shelly 2PM Gen3 is rated 16A per channel, versus 10A on the Shelly Plus 2PM, so it can drive heavier loads. For most lighting and shutter circuits either is sufficient, but the Gen3 has more headroom.

Buyers who want a proven, safety-rich two-channel relay for roller shutters, blinds, curtains and gates on a budget, with per-channel energy monitoring and fully local Home Assistant control, and who do not need Matter or HomeKit.

Anyone who wants a two-channel cover relay with Matter and Apple HomeKit support and a higher 16A current rating. The Shelly 2PM Gen3 also works as a Bluetooth gateway during setup.
