You should read the first post of this topic for intructions.
You need to setup first the Zigbee2MQTT server where you configure SLZB-06 as the zigbee controller. You will also need MQTT broker and finally you can setup this app.
SLZB-06 must be in controller mode and there is no support for the hub mode.
I have installed Z2M on my synology and homey. First I added several tuya indoor and some nous A4Z outdoor double plugs to have a decent mesh to build on.
However, the Nous A4Z are powering off by itself and I dont know why. So far I created no flows for themselves. I cant see why they are powering off in the z2m webfrontend. Homey just says that they were powered off by z2m. Its the same info no matter if the auto power off or if I power them off in webfrontend myself. Just toggling in homey makes a difference in the homey device log.
I also tried updating the Nous A4Z firmware on the OTA page but they are the only devices without fw info although they are listed as compatible.
Any hints how I could tackle these issues?
