Shelly 1PM Gen4 is the first Matter-compatible, multiprotocol retrofit MINI relay module from Shelly: it supports Wi-Fi + Bluetooth protocols (with Shelly's cloud or as a local smart home solution), as well as Zigbee 3.0, so it can be paired with a wide range of Zigbee 3.0-compatible hubs. The Shelly 1PM MINI Gen4 supports only wet contact switching as as it is equipped with a metering function. The Mini version is 8A, so it is primarily recommended for installation behind light switches.
