Tuya TS0601_dimmer_knob not reporting back (after upgrade to v2.1)

[sbolten]

Discussed in #26143

^{Originally posted by sbolten February 3, 2025}
Hi,

since a while I have these dimmers (https://www.zigbee2mqtt.io/devices/TS0601_dimmer_knob.html) up and running.

They are recognized in Z2M as follow:
Zigbee-Modell: TS0601
Zigbee-Hersteller: _TZE200_p0gzbqct

I can change status from Z2M GUI without any problems (light on/off, dimming).

But: changing the status on the physical device does not report back to Z2M (after re-pairing only the very first small change is reported back but after that changes through the physical devices are not reported back to Z2M).

Now - I am not 100% sure - but I think this worked a couple of days ago. Maybe I am wrong and it never worked (I only recently introduced a dashboard showing the status of the dimmer...).

What can I do about this? Is it maybe related to upgrade to version 2.1?

Best regards,

Stephan

I am having the same issue with the same Moes / Tuya dimmers after updating to 2.1.0.
2.0 and earlier were working fine.

Could you provide the debug log on 2.0.0 where it works and 2.1.0 where it doesn't work?

See this on how to enable debug logging.

Logfile from 2.1.0: https://gist.githubusercontent.com/wimb0/6dc7a2fd4f83ac9acf9bcb70f03bf21f/raw/b76d0723a0782765f373462b4d522d6bc061f959/log.log

This was the state according to Z2M when the logfile was created:

This is wrong, because at that time, moes_dimmer_eettafel, moes_dimmer_keuken and moes_dimmer_woonkamer were on.

Based on the log I tend to say it is the same issue as in #26124.

On 20:49:08 your device proactively reported its state with seq=1. On 20:49:57 you turned it on, the device reported its state but again with seq=1, due to a change this packet is now discarded as there was already a packet with seq=1. I already proposed a fix for tha.

Exactly the same problem here with these dimmers.

[Koenkk]

Should be fixed by Koenkk/zigbee-herdsman-converters#8723

Changes will be available in the dev branch in a few hours from now and in the next release which is every 1st of the month.
