Error Message Unsupported CI Field 79, remaining payload is... [closed] #116

Closed TobiasSt78 closed 1 year ago

TobiasSt78 commented 1 year ago

Hello, great adapter but not 100% compatible with Kamstrup FlowIQ2200 water flow meter

I get every minute a error log: "Unsupported CI Field 79, remaining payload is 05099bf700000000190200008a0105f0ffffffffe123fa130000da04000011"

Nevertheless, the adapter works and gets infromation from the water flow meter. I have tested Version 0.8.6 and 0.8.8

My Setup; CUL /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A50285BI-if00-port0 C/T Mode 38100 [X] Cache for compact telegrams.

Cheers, Tobias.

This sounds very weird. If you have turned on the compact telegram cache, you should not see this message... Could you please provide a debug log?

TobiasSt78 commented 1 year ago

Do you have a hint for me how to get a debug file from the adapter?

lvogt commented 1 year ago

To turn on debug logging you need to:

OK, here comes the debug. I need to delete all objects and restart the adapter, otherwise, it won't get new values. I just changed the AES key in the data below to ensure privacy.

Thanks for the log. The manufacturer is decoded as KAW instead of KAM - therefore the compact frame cache does not work. I will try to investigate it.

I also edited your post to make it a bit shorter with only the (probably) relevant part of the log.

TobiasSt78 commented 1 year ago

Thanks a lot. Do you need any further information? I can also share the key if necessary but not in public ;-)

lvogt commented 1 year ago

Ok the anwser seems pretty straighforward, Kamstrup also uses KAW as manufacturer ID (Kamstrup Water seem to be the intention)...

I just removed the manufacturer ID check from the compact telegram handling in 0c2c4ae (v.8.10). Now you should only a "Unknown compact frame format" message a few times after an adapter restart until a full telegram was received.

The new 0.8.10 version works without breaks. Thank you! Great job.
