3EF0 - byte 5: 08

I've just started seeing lots of these messages in my HA log.

They seem to have started when the boiler was serviced, and have continued since then. May just be coincidence, but....

ramses rf 0.42.0
Intergas boiler
Opentherm bridge (R8810A) with OTGW

Having looked into this further, I think this byte maybe the OEM Fault Code. The value of 8 was appearing against this description in OTMonitor, and both this, and the warnings in the HA logs, were cleared by a power cycle.

i'm curious - what did code 08 mean?

[lloyda]

At the moment I have no idea. The boiler itself was showing no error codes. The first appearance did coincide with when the boiler was being serviced, so maybe something during the service induced a temporary fault.

The OEM fault code is part of OT MsgID 115, but I did not see any of these whilst monitoring with OTGW. Post boiler (and OTGW) power cycle, some messages with id 115 did appear, but set to zero. So still not sure exactly what was going on.
