zigbee2mqttt blinds problem

[sundodger]

Hi all,
Recent updates seem to have broken my blinds setup.
Clicking on open or closed gives either
Error: Zigbee: Blind switch: unable to handle command "Open"
or Error: Zigbee: Blind switch: unable to handle command "Close".
Getting this in the log.
Oct 16 10:32:15 raspberrypi npm[537]: Zigbee2MQTT:debug 2022-10-16 10:32:15: Received MQTT message on 'zigbee2mqtt/0xb4e3f9fffe61e9a2/set' with data 'null'
Oct 16 10:32:15 raspberrypi npm[537]: Zigbee2MQTT:error 2022-10-16 10:32:15: Invalid message 'null', skipping...
i can still control them with the slider or a set to a % command. E.G i have two controlled as a group. turning on the group sends a set to 98% level which works to close them but the off to open them now does nothing.
Any ideas or workarounds that you know of would be welcome.
Thanks.

As designed in Domoticz Beta (be carefull about his!!!)
New functionality is described here: viewtopic.php?t=39192

If you are using the Python plugin please check the repository for updates.

Hi, I was reading the changes and did update everything to the latest (as of yesterday). Maybe it will take a while to catch up..

@sundodger, please create a issue on github
Please make use of MQTT Explorer, and include the config topic + payload of your blind
(<mqtt auto discovery topic>/xx/yy//config)

Here the same. After update to 2022.2 blinds not working anymore

Error: Zigbee: Blind switch: unable to handle command "Open"
or Error: Zigbee: Blind switch: unable to handle command "Close".

Fixed the problem

Solution is to adapt next source-file of plugin:

zigbee2mqtt\devices\switch\blind_percentage_switch.py

Change 'cmd == 'ON' into 'cmd == 'CLOSE'
Change 'cmd == 'OFF' into 'cmd == 'OPEN'

Top Tip!! This indeed solved my problem with the zigbee blinds after upgrading Domoticz, zigbee2mqtt and the plugin.

My Pi crashed a few days ago and since there is almlst no Pi's available I went to an Odroid N2+

Thanks very much.
