flexit_bacnet.bacnet.DecodingError: unsupported response type: 7 #17

Open lellky opened 7 months ago

lellky commented 7 months ago

Trying to implement sensors in the home assistant integration flexit_bacnet craches after a while (probably when polling sensor values). It seems to work the first time.

Here is the added code in core: https://github.com/lellky/core/commit/3cfb6b9dc6cc70f4babf83ade6b2276e4a5cdc0b

This is the error output:

The above exception was the direct cause of the following exception:

As we discussed, this is an abort message from Flexit unit with reason "out-of-resources". That's due to too many request being sent by the home assistant - but as this is now fixed on your end with the use of HA Coordinator, I'll not rush fixing it. Let's keep the issue open, so I remember to add bacnet's abort response support to the code.
