Hi again,
I am running zigbee2mqtt service to control Zigbee switch plug. It works and I can see state is changing.
Now I am trying to integrate zigbee2mqtt with Gladys.
and on the server side I got an error message:
2023-05-25T08:29:19+0200 <debug> zigbee2mqtt.controller.js:22 (getManagedAdapters) Get managed adapters
2023-05-25T08:29:19+0200 <debug> zigbee2mqtt.controller.js:33 (status) Get status

2023-05-25T08:29:23+0200 <trace> errorMiddleware.js:49 (errorMiddleware) PlatformNotCompatible [Error]: SYSTEM_NOT_RUNNING_DOCKER
P.S. I am running Gladys in development environment:
Hey @sigidagi 
Currently, we do not support connecting to an existing Zigbee2mqtt container in Gladys, we only support starting a Zigbee2mqtt Docker container from Gladys (hence the Docker requirements)
As you are running Gladys in a developpement environnement (and not from inside the official Docker container), this integration will not work
For the future, @atrovato is working on making it possible to connect to external already-existing Zigbee2mqtt instances 
Hi @pierre-gilles
Thanks for your answer,
Ok, I disable local zigbe2mqqt and installed gladys docker. It is running and I have three containers: gladys, mqqt broker and zigbee2mgtt.
Added Philips switch.
As far as good.
But UI is not that intuitive. I was expecting some toggle button to able to control this switch device. Where I can find it?
P.S. Zigbee2Mqtt frontend was working but I needed more nicer UI (also for mobile phone), so I was looking for gladys 
Go to the dashboard (home) and add a box « devices in room » with that device 
Note: your device needs to be defined in a room in the Zigbee2mqtt integration
Thanks @pierre-gilles ,
Yes I have added room and device to that room - I have now toggle button!
I can see that mqtt broker exposes 1884 port, so I would like to publish some other (not zigbee) devices to the broker, i.e. temperature sensor data. I expect that Gladys will recognize as another Zigbee2mqqt device?
I have tried to test connection:
mosquitto_sub -p 1884 -t '#'
Connection refused: not authorized.
What is username and password?
Cheers

If you want to do that, use the MQTT integration and our MQTT API 
Follow this tutorial to do that :
