Shelly 1PM Gen 4 | Smart Switch with Power Monitoring
The Shelly Mini 1PM Gen3 is a smart relay with built-in power metering, able to control a range of electrical appliances and support a maximum load of 8A. The relay is compact without comprimising on functionality and can be controlled individually through the free Shelly mobile app and one of its 200+ integrations (Amazon Alexa, Home Assistant and more) or configured as part of a wider synchronised schedule or scene involving multiple Shelly devices. The Shelly Mini 1PM Gen4 is the most recent installment in Shelly's Mini series, featuring an updated chipset and a greater RAM capacity than the Gen3 to allow for more responsive operation and more sophisticated scripting capabilities. All Gen4 models, the Mini 1PM Gen4 included, are also compatible out of the box with both Matter and Zigbee as well as the Bluetooth and WiFi compatibility of the Gen3 versions, and can maintain these connections simultaneously; this means that the Shelly Mini 1PM Gen4 can simultaneously connect to a wider Shelly network over WiFi, and communicate with existing Zigbee or Matter installations for an all-in-one solution. In addition to its smart relay capabilities, the Shelly Mini 1PM Gen4 features sophisticated and accurate power measuring, and is able to measure the energy usage of any connected device with an accuracy of within 1%. This data is then stored both locally in the device and securely in the cloud, offering a unique birds-eye-view over the energy consumption of your Smart devices.
