It is possible to set up underfloor heating control with Shelly. It is simple to do with the “thermostat” function in the Shelly Smart Control app. This guide describes what you will need and how to set up automatic control of water based and electric underfloor heating systems.
What you will need
Relay
First, you must select the right type of relay for controlling your floor heating. The relay you might want to use can vary depending on your type of heating. Here are some recommendations from me.
Water underfloor heating
Water underfloor heating is often controlled centrally. Therefore, I recommend devices with multiple outputs for DIN-rail mounting. In this way, you can make a nice control box.
Shelly Plus H&T can be powered with batteries or with a USB-C cable.
Programming
To set up automatic heating control, you can use the “thermostat” function in the Shelly Smart Control app or on the web interface control.shelly.coud.
