From the log:

12:24:09.107921 T001A7FFF Read-Data DHW temperature (MsgID=26): 128.00 12:24:09.282683 B401A1520 Read-Ack DHW temperature (MsgID=26): 21.13 12:24:09.599133 T90383700 Write-Data DHW setpoint (MsgID=56): 55.00 12:24:09.900696 B50383700 Write-Ack DHW setpoint (MsgID=56): 55.00 12:24:10.105121 T00197FFF Read-Data Boiler water temperature (MsgID=25): 128.00 12:24:10.311940 Error 04 12:24:10.314347 EC01118E0 12:24:10.597268 T00197FFF Read-Data Boiler water temperature (MsgID=25): 128.00 12:24:10.919690 BC01918E0 Read-Ack Boiler water temperature (MsgID=25): 24.88 12:24:11.108307 T00110000 Read-Data Relative modulation level (MsgID=17): 0.00 12:24:11.321138 BC0110000 Read-Ack Relative modulation level (MsgID=17): 0.00

The MQTT value in HA for rel mod level is 24.88 as shown in the image, but the log shows that 24.88 is boiler water temp.

Another example:

Seems to be related to the Error 4 just before these occurrences?

I will have to look into this, is this still happening?

chokays commented 1 year ago

Yes, from the first use of the OTGW

I'm still having the issue

rvdbreemen commented 1 year ago

It seems that this is cause by decoding and sending messages with parity error. Just fixed this in dev branch. If you are on Discord community channel, you can help test this by using the beta. So please join: https://discord.gg/mSQBYBMNRy
