TS0601 (_TZE200_whpb9yts) stopped responding to brightness requests

[elgerg]

What happened?

I upgraded to 1.38.0 from ~1.36 (before the automatic identification of capabilities was introduced) and now my dimmers dont work correctly. Sometimes the state ends up being the brightness so randomly wont turn off.

However the main issue is that I cant adjust the brightness anymore. only turn them on and off.

Even using the web UI (sending the right MQTT payload) does nothing.

EG sending the following payloads:

didnt change the brightness in any way.

What happened or what am I doing wrong now?

Thanks

What did you expect to happen?

I expected the brightness to go up or down depending on the value supplied.

How to reproduce it (minimal and precise)

Oh it gets worse. When I change the values by using the physical button it doesnt report back :(

Actually it does but as the min brightness value..

This is getting even more bizarre.

If I set the min brightness slider in the front end then the brightness changes. However the brightness slider does not move.

Has brightness been replaced with min brightness?? If so why is brightness still there and no release notes that state this has been deprecated and why is the brightness slider still there?

Thanks

[elgerg]

Having reverted to version 1.36.0 and then updating one version at a time I can confirm that the brightness slider and min_brightness start to get messed up from version 1.37.0 onwards.

This seems to be the case for the dimmer and a GL-C-008P (although this might be a red herring)

I suspect something went wrong here:
Koenkk/zigbee-herdsman-converters#7231

Easy update/downgrade script that works:

sudo systemctl stop zigbee2mqtt

cd /opt/zigbee2mqtt

#backup data
cp -R data/* /home/pi/data

git pull origin 1.37.0

#if downgrading
git reset --hard FETCH_HEAD

npm ci
npm run build

cp -R /home/pi/data/* data
sudo systemctl start zigbee2mqtt
sudo journalctl -u zigbee2mqtt.service -f

@Koenkk

I've just set up a test lab using the latest version for testing purposes:

When changing the brightness from the light switch only the min_brightness value is passed (it should be brightness).

{
    "linkquality": 94,
    "state": "ON",
    "min_brightness": 254
}
{
    "linkquality": 94,
    "state": "ON",
    "min_brightness": 240
}
{
    "linkquality": 94,
    "state": "ON",
    "min_brightness": 220
}

Now sure where to go with this as I cant upgrade as most of my home automation for my lights will stop working properly.

Thanks in advance

[Koenkk]

Could you check if the issue is fixed with the following external converter:

• save this as file next to configuration.yaml as ext_converter.js
• add it to configuration.yaml:

external_converters:
  - ext_converter.js

• start z2m, check if issue is fixed

[elgerg]

Hi @Koenkk

Yep, that external converter has fixed the problem in my lab.

What is the next step?

Thanks!

[Koenkk]

With 1.36, was the min brightness working?

[elgerg]

I dont think it worked with these dimmers but I never really used it.

I've just tested min brightness and it does seem to make a difference..

Thanks

[Koenkk]

Great, integrated the fix!

Changes will be available in the dev branch in a few hours from now.
