Hi All,
In my house I have central(City) heating system.
The only way I can control heating is just turn the radiator on/off
Can someone advice me how to automate this.
The only product that I have found are from Conrad
Problem both products have no interface for domotica.
the ugly one has remote controlling option on 868,35 MHz

The top one seems very similar to the Honeywell HR80, which is also controllable over 86x MHz. I did quite some research and I'm afraid it's the only acceptable solution...

The Honeywell version is the cheap version HR20..there is no remote control for this one.
If i can control HR80 from HA i will go for that one.
the prise of HR80 is +/- 140 euro
HR20 cost at the moment about 35 euro.

I have found HR80 units on eBay for prices a low as 60 Euro a piece when ordering 5 pieces. These units were brand new, from a German supplier.
