    I did wonder about sticking the CC1101 onto the ESP, but I have a spare nano clone about so I think I'll put it on there and attach it to the computer running OpenHAB. There's some software that will...

    It claims to support OpenTherm, but when I spoke to Atag they told me it's such an old version it wouldn't work with the Evohome bridge. In any case, I can now dial up any temperature from 20-90C on...
