BHT-6000-GCLW - Unknown MCU command

[joolui]

Hi!

I updated to 1.34 and 1.35 but in both cases there is an error message every 2s on my mqtt broker. Thus it fills up the log very quickly. Otherwise everything seems fine.

{
"error": "Unknown MCU command: 55 aa 01 07 00"
}

BHT-6000-GCLW - Gas boiler version

Can you please check. Earlier had no issues with the firmware. If you need more info/testing, please let me know.
Thanks, LAjos

Hi Klaus,
I do have the same issue even with Firmware 1.38 on BHT-6000.
Not sure which Firmware version the problem started with, because in clearly older Version there was no issue.
Any suggestion?
best regards
Peter

I now did a downgrade to firmware V1.19 but still get an error. Its a bit different but still an MCU error:
V1.38 shows: {"error": "Unknown MCU command: 55 aa 01 07 00"}
V1.19 shows: {"error":"MCU: 55 aa 01 00 00 01 01"}

thanks

And V1.19 shows up with 2 different additionl errors:
{"error":"MCU: 55 aa 01 07 00 08 03 02 00 04 00 00 00 29"}
{"error":"MCU: 55 aa 01 07 00 08 66 02 00 04 00 00 00 00"}
Maybe that helps to identify the source of the errors...
