Xiaomi Wall switch group message support question

[pkedvessy]

Hi All,

I'm really interested in the zigbee groups feature to control multiple Xiaomi Wall Switches by a single MQTT command.

I can see that how we can send messages to a group, but sending control messages to these switches is a bit different because they are using separated topics for left and right relays.

Is it possible to apply the group functionality for these switches? If so, how we can set up them?

Thanks,
Peter

First we have to check if this device support groups. Could you try to add it to a group the way it is now? Then either the left or right button should be in a group.

Sorry for the late response.
Finally I was able to have a try with a "Xiaomi Aqara Neutral Line Type Remote Control Switch": it got added to a really new group (lets say 'test'), but when I have tried to send '{"state": "ON"}' message to '/bridge/group/test/set' I got the following error: '{"type":"entity_not_found","message":"bridge/group/test"}'

You should send the message to zigbee2mqtt/test/set {"state": "ON"}

Ahh, thanks, it is working now: left is in the group. Can we add right as well or can we configure somehow which one is in the group?

This was not implemented yet but can now be done in the dev branch. (http://www.zigbee2mqtt.io/how_tos/how-to-switch-to-dev-branch.html). Documentation: https://github.com/Koenkk/zigbee2mqtt.io/blob/dev/information/groups.md#adding-a-specific-endpoint

Should I update my coordinator's firmware? I'm experiencing issues when starting zigbee2mqtt but I have no issue with the master branch...

[pkedvessy]

I missed to say thank you for the quick turnaround on having support on my request! It's going to be more than brilliant to controll both channels by group messages!

I have updated my coordinator to Z-Stack_Home_1.2 version 20190425 and dev branch is working as expected. But when I'm trying to add a specific endpoint to a group, I get this error:

Did you configure a base_topic in configuration.yaml?

[pkedvessy]

Yes I did: zigbee2mqtt/ground_floor

[Koenkk]

Can you post your configuration.yaml?
