I was sure I set the channel but can't seem to find it in my code.
I definitely set signal strength and speed though. Had to be highest strength and lowest speed to get what I have - which isn't as good as I wanted.
I'll have a proper look at it in a few weeks when university stuff is all finished with.

You can definitely set the channel. I assume it uses a default channel if you don't set one manually. There's a scanner sketch for the Arduino, maybe the Pi too, which shows interference on each channel.
And my heating didn't come on at the start of the week. I tried loading my web interface and it said "Can't connect to boiler :(" I thought something was broken but the radio connected to my Pi had slipped down the side of my subwoofer behind the telly and blocked the signal.
:'D
The morning my original setup failed wasn't fun, very cold morning!
:) I think I've moved it somewhere it should be ok now.
Brr. Cold mornings aren't good. Working again now?
It's been rock solid for as long as I can remember now.
