Off the shelf solution?
« am: 01 April 2018, 10:29:22 »

There didn't seem a suitable forum to post my question in so I've opted for English Corner since I'm posting in english.

I've had a change of plans forced on me.  I was going to have a heating system with max thermostats on all radiators with fhem running on pi and a home brew interface to the boiler via an opentherm interface.  Now I want something off the shelf as I think a custom system like I was going to do would put off a buyer of the house.  Ideally I'd still like to use max thermostats on the radiators as I've bought them.  The boiler will take an external sensor to adjust the water temperature so I can use that to control the return flow (i.e. run cooler during spring/autumn for greater efficiency).  Hence I could run boiler on/off as normal.  Is there any off the shelf solution for max to enable the boiler if there is demand from the radiators?

Or any suggestions for off the shelf solutions?  Ideally I'd like some spare i/o for other functions too but bottom line is I want something that won't put off a prospective house buyer.
