I installed a 4 underfloor zone plus 2 valve zone system about 10 months ago. Its worked perfectly through the winter and up till now however this morning we noted several COMMS FAULTS with sensors and all the BDR91s were showing static red LEDs whereas they always had previously been fine.
To top it off the underfloor BDR91 would not connect at all with the HCC80R which is about 15 metres away (the other BDR91's will re-establish comma when the controller is close but can't tolerate it being moved back to its normal position).
Another interesting fact is our Hormann Garage door remotes (also on 868MHz) have a significantly reduced range to the point where they cant open the garage when the door is closed - 2 remotes so not a battery issue.
So my thoughts:
1. External 868MHz interference - either a new gadget the neighbours have or maybe roll out of 4G in my area (I do hope not but what problems have oothers had)!
2. Local interference - I plan to go round turning things off tomorrow in case a fridge or something is malfunctioning.
3. A malfunctioning Evohome device messing things up - no sure where to start as all LEDs appear appropriate. Do devices emit continuous signals when faulty?
Anyone come across this before - and what was the solution. I have moved the controller next to the boiler and hot water relay in the garage for now but I want to fault-find a solution to this weird problem in the next week and certainly before autumn - and want to get my garage door working again.
