Evohome and BDR91 communication (daily) defaults

$

Hi all,

I recently changed both my boiler and BDR91 relay - and they are connected to my (legacy) Evohome. Since then I receive a communication error on my Evohome every day.
I noticed from the default logs that the error is happening every day and about 10 minutes later each day (see attached picture, it’s quite regular).

I tried moving a bit the BDR91 relay around (my previous BDR91 was located at the same place and I never had issues) and I tried to turn it off/on. I also tried to "unbind" BDR91 and Evohome, then binded them again, cleared logs as well - however it has not solved the issue.

From past discussions on this forum, I see this could be caused by "multiple bindings". However I'm using only one BDR91 and Evohome is controlling the heating only (not hot water - since I understand that can be a source of double binding if not carefully configured).

The only change since this issue is that I have a new boiler and a new BDR91 relay (legacy Evohome has not changed, I just paired it with the new BDR91 relay).

Overall the system is working fine (the boiler is correctly controlled by Evohome via relay), it’s just that those errors are a bit annoying. Any idea ?
