Shelly 2PM Gen3 vs PM Mini Gen3 (2026): Which to Buy?

Updated September 2026

Data from Amazon and official Shelly site.

2026 verdict

Winner

$14.49

In this smart relay matchup, the Shelly PM Mini Gen3 pulls ahead mainly on price and matches the core Wi-Fi and Bluetooth connectivity of its pricier sibling, but that win comes with a catch: it only measures a circuit's energy use and cannot switch anything on or off. The Shelly 2PM Gen3 answers as a genuine two-channel switching relay, with an interlock mode purpose-built for roller shutters, blinds and garage doors, and it also stretches further on integrations by adding Matter and Apple HomeKit alongside Alexa, Google Home and Home Assistant. Neither module supports Zigbee, Z-Wave or Thread, so both depend on a steady 2.4GHz Wi-Fi connection for day-to-day control or monitoring. Buyers who need to control two circuits or automate a cover should go with the Shelly 2PM Gen3, while anyone who just wants an affordable, precise way to track a single circuit's power draw in Home Assistant gets more value from the Shelly PM Mini Gen3.
