Hmmm... the whole POINT of Evohome is no long cable runs.

Not everything can or has to be wireless. It's enough that the radiator valves are wireless IMHO, I don't care if there is a bit of extra wire from my hot water cylinder to my hot water zone valve even if they weren't already both right next to each other.
Besides, most traditional control systems that Evohome would be replacing would already have a hard wired connection from the hot water cylinder sensor back to the zone valve.Last edited by DBMandrake; 15 July 2018, 08:34 PM.

It is the wireless element of Evohome that I see as its biggest weakness and the most frequent cause of problems with its operation. The hot water (DHW) control via a wireless battery-powered CS92 is the most extreme example of an unreliable component. I like DBM's suggestion of a mains powered combined BDR91 / CS 92 which would be a huge improvement.Last edited by Edinburgh2000; 17 July 2018, 08:36 AM.

If you're a bit handy yourself, this might be an idea: https://www.youtube.com/watch?v=Sa18...szHaYC&index=1

Neither of these issues is solved by adding a mains operated battery substitute as the battery saving algorithm will still be in effect, and the device will still be using wireless comms.
