Underfloor heating according to current weather
Shelly Pro 1 and Shelly Pro 2 can be used to control underfloor heating based on the current weather forecast, sensor data (ie Shelly Flood) or according to a set schedule. Make sure the temperature of your business or home is always friendly - whether it's a yoga studio, a gym locker room, a spa or your own living room!
No Hub required
Shelly Pro devices can be controlled directly and without a hub via a smartphone using the Shelly Cloud Application. Manage and control all the smart devices in your home, set up quick profiles, scenes, schedules and adjust settings wherever you are, via cloud access or only on the local network!
Supported platforms
Use devices with your one local or centralized server - you can keep them fully isolated from the public Internet. The Shelly Pro series is compatible with Home Assistant as soon as it is unpacked. All other home automation solutions can monitor and control Shelly Pro devices using CLOUD, REST, MQTT and UDP protocols. Shelly devices can also be grouped with all Shelly devices as well as other smart home devices on the home network.
