Hi, I came across this forum when doing some research into possible solutions for an issue I have with the Evohome system.
I know it's a bit of a first world problem, but it appears the construction and size of my home is a bit of an issue when it comes to the Evohome being able to maintain decent communications to all the radiators in the property.
At present I have 29 radiators and 2 underfloor heating zones controlled by the system, hot water and two boilers.
It's currently been split using two control panels, one for upstairs one for downstairs, set into a total of 20 zones.
It's been a bit of trial and error in positioning the base stations, and I've managed to get them in positions where they maintain contact with most of the actuators (although in order to do this the base stations have ended up in less than ideal locations).
However they do still occasionally lose contact with some of the zones/actuators for hours at a time. Almost all the walls in our house are solid, and due to the way it has been extended, a few internal walls are actually double skin cavity walls.
I'm surprised to find that honeywell don't make some form of plug in repeater to resolve this problem.
I've also found that the orientation of the base station also seems to affect the reception of signal from the HR92's. If it is at 90 degrees to the HR92, then it appears the reception is not as good. I tested this by doing the rf check for a zone I kept losing, it was showing 2 poor and occasionally 1 poor and 1 not received. As I rotated the base station so the back was pointing squarely in the direction of the HR92's this changed to "2 good".
I have tried changing to lithium batteries as I hoped the settings in the HR92 would then take advantage of the extra mAh of the batteries and boost the signal to the base station.
I don't think this is an issue with the base station as the valves report a signal which although occasionally poor at 1, usually ranges between 2-4. However the base station reports only poor or occasionally not received. So I think this is an issue with the strength of signal coming from the valves.
I've even tried bodging some tin foil deflectors to try and concentrate the signal from a valve in the direction of the base station.
I'm now starting to struggle for ideas on how to get this to work.
As I see honeywell are active on here I'm hoping there may be a solution or even the possibility of being Guinea pig to any possible booster solution being worked on.
Many thanks, Chris.
