Short Description
Shelly 1 Mini Gen3 is a compact smart switch with potential-free contacts, enabling remote control of electrical appliances via smartphone, tablet, PC, or home automation systems. It operates standalone on a local Wi-Fi network or through cloud-based home automation services. This device is an upgraded version of the Shelly Plus 1 Mini, featuring a more advanced processor and increased memory.
Remote access, control, and monitoring are possible from anywhere with internet connectivity, provided the device is connected to a Wi-Fi router. The unit can be retrofitted into standard electrical wall boxes, behind power sockets, light switches, or other space-constrained locations.
It includes an embedded Web Interface for monitoring, controlling, and adjusting device settings.
