I have water borne heating in every floor in my house. It came with a system called Seitron New wave.
It uses an active antenna : Active antenna for DLP modules (seitron.com)
That transmits on the frequency 868,150 MHz.
In every room there is a thermostat that is wireless and transmits to the active antenna on 868,15 Mhz frequency.
The relay system to each room is this module: 8 zones relay module with pump output (seitron.com)
And I also have a 2 zone relay module in my second floor.
Just wondering if Homey is compatible with this, so I can use Homey to control the temperature in each room.
I see that Homey transmits on the same frequency 868 Mhz.
But wanted to check if anyone else has tried Homey against Seitron.
