Description

I made a fan controller based on the Arduino example 'Zigbee_Fan_Control'. It works well most of the time, with low latency and behaviour as expected, but maybe 1 in 10 times, it simply ignores the command from Home Assistant. No failure message, no warning. A manual retry usually succeeds. I believe the Zigbee protocol implements an acknowledgement signal from the device, so if this is the case, it's being ignored. There seems to be no attempt to retry the transmission, and so in effect Home Assistant is blindly sending commands and hoping for the best. This sadly isn't good enough for a robust home network, and if the problem exists in this example I expect the behaviour is the same in all the other examples. Is this a problem with arduino-esp32, or Home Assistant, or both?

Without any logs what exactly happens or not, no help is possible.

Do you mean serial debug logs from the ESP32, or from Home Assistant?

I was under the impression it was working as designed, that failed sends are simply not checked for; I'm seeing this behaviour from the unaltered example file after all.

Is this not the case? Is the communication between HA and the ESP32 meant to include any acknowledgement or retry function?

[lbernstone]

Zigbee messages do have an ack, but if you don't look at the logs, how would know that it didn't ack?
More information would be needed to answer your question about logging. If you are using ZHA, the instructions are here. On the arduino side, set core debug logging to verbose (although info should be enough).

I agree with @lbernstone. Please set core debug logging to verbose and also a Zigbee mode -> ed or zczr with DEBUG.
Without any logs it's hard to help. The ack is supported and you can take a look how its implemented in the Sleepy Temp/hum example.
