Hi,<br>
<br>
Posting this on behalf of Steve R who I hope is in the process of joining the interest group (please direct responses there, only, for now):<br>

Subject: Open TRV what's going on<br>
<br>
<br>
Hi, I am quite interested in the notion of the open trv, but - for my purposes<br>
at least I think it is a bit over the top. I am using a biomass boiler that we<br>
run to heat up a 2000l accumulator tank. I control the heating with a hand<br>
coded rasbperrypi and a couple of energenie plugs to turn on the pump for the<br>
house and hot water. I have been craving after something like the OTRV for a<br>
while, so I can spot heat the house, so bedrooms in the morning living room in<br>
the evening with a sensible default temperature for the house.<br>
<br>
What I would like - I think - is the hardware so I can try to hook it up to my<br>
existing system. I can't figure out how to do that from the website(s).<br>
<br>
Is it possible?<br>
<br>
Steve<br>
