R8810A, binding problems

[emmeesse68]

there is an OpenTherm test tool but if you think that there's an issue I would simply recommend exchanging it.

I would also double check that it is bound correct as an OpenTherm Bridge under SYSTEM DEVICES

It is spaced 300mm away from metal objects I assume?

My reseller manged to get me a new R8810 from Honeywell, and that made the difference... bound at first attept, now my boiler is much more responsive to changes done at the controller.

I think this demonstrates that my old R8810 was somehow faulty, at least at the RF interface. I'm still observing it but since yesterday night it seems to work great... Unless some other surprise shows up, problem solved...

Merry Christmas to everyone!
