What is Shelly Plug S Gen3?
The Plug S Gen3 is the third generation of Shelly's compact smart plug, and unlike most plugs in this price bracket it includes power monitoring as standard rather than as a step-up feature. That makes it genuinely useful for finding which appliances are driving a bill, not just for switching things on and off remotely. It combines Wi-Fi with Bluetooth, supports schedules and automation, and works with Home Assistant, Amazon Alexa, Google Home and Apple HomeKit, plus Matter on the MTR variant. That breadth is the reason Shelly has a following among people who want local control rather than cloud dependence. Shelly sells an unusually deep catalogue around it, spanning relays, energy meters, sensors, thermostats, wall displays and smart locks across Wi-Fi, Zigbee, Z-Wave, LAN and KNXnet/IP.
