I've raised a support call with Resideo, but I'm not quite sure they'll manage to assist
![Very Happy :D](./images/smilies/icon_e_biggrin.gif)
I've a setup working fine for the last 5 years, with a R8810 and a OpenTherm compatible boiler (based on a LMU64, and its an Atlantic boiler)
I monitor all the Evohome RF talk with an HGI80, and it seems the R8810 stopped working last night (for no reason).
I've tried to reset it (15 seconds on the button), but with no luck, no led (red or green) anymore.
I've tried to check if I can test the RF comms between Evohome & the R8810, but I cannot find how to put in 'test mode' the R8810.
As a fallback, i've switch back to using the BDR91 as an On/Off relay, and the boiler is now controllable again (albeit more stupidly as only in on/off mode).
Has this ever happened to anyone (a R8810 dying suddenly like that) ?
I'm wondering if there is an issue with the LMU64 itself or if it's just the OT Bridge that died.
I have a OTGW sitting idle around, so I may try to listen to the OT talk and see what I can make out of this, but any feedback would be of great help
