5 Temperatures show incorrect values

[panosnl]

All values seem to come correctly from my Q600 into MQTT.

However 5 temp values show strange behavour: They cycle simultanuously the same (incorect) values: 0, 128, ~600) the latter value changes over time.

[vekexasia]

hey @panosnl Maybe they changed the protocol? looks like you've a diff metric (not temperature) at those locations.

[panosnl]

Does anyone have temps running OK on firmware 1.9.1? Is it possible to down/upgrade without the LAN interface?

Is there anything I can do/help to fix this?

Update:

I noticed that the bogus values are updated every second. However I do see correct values coming by at a 'normal' rate that is expected 10-20 sec.

This means that the values are sent correctly after all but incorrect values are injected somehow. @vekexasia Could it be that the decode for these parameters is falsely triggered ?

[vekexasia]

so to make it clear you get "invalid values" AND "valid values" ?

It could be a bug in my code for the firmware 1.9.1 that can't decode values. Can you isolate just one metric and the raw you get annotating them?

[panosnl]

Yes. that is hove it seems to be . outdoor temp is 24.1. I put some outdoortemp loggings in bold.

also it seems that Message : 1450201 X 10 gives both 0 and 128 ....

Cleaned up debug (decoded line needed a LF):

[vekexasia]

Message : 1450201 X 10 Decoded : outdoor_air_temp - 128.0 and Message : 1450201 X 10 Decoded : outdoor_air_temp - 0.0

there is something wrong within the decoding then. Cause looks like same emsage provides 2 diff values.

Can you give it a try and reset it to 0 before decoding?

[panosnl]

Can you give it a try and reset it to 0 before decoding?

I am happy to try . Please tell me how I can do that.

[masafra86]

I have the same identical problem. Those 5 temperatures get quite strange values (0, 128, 500). I don't know how to debug them. Additionally, I'm not able to send commands to the uniting I can't understand why

[vekexasia]

Hey guys can you try to change line 136 of message.cpp to this?

uint16_t PDOID = (frame->id & 0x01fff000) >> 14;

? There is an added 1

Thanks for the fix.... No weird values anymore it seems.

[masafra86]

I confirm for the values. Now, what about the commands? Do you have any fix to give?

[vekexasia]

can you open a new ticket masafra please and link it here? so that anyone else having issues with command can relate.
