I am running Hass.io (HassOS 2.8) with a Raspberry 3 b+ and a ConBee USB Stick by dresden elektronik for providing a Zigbee Router. I have installed the official deCONZ plugin through the hassio addon-store.
The setup works so far with IKEA Lamps. However, I want to add to deCONZ a Zigbee Heiman Plug which apparently is not supported by the user-friendly Phoscon app. So, I think I would need to add the Zigbee Plug manually by using deCONZ REST API (https://github.com/dresden-elektronik/deconz-rest-plugin).
It seems to me that deCONZ REST API plugin was not installed by the official deCONZ hassio addon. Because when I send a GET request to https://dresden-light.appspot.com/discover (as it is instructed here http://dresden-elektronik.github.io/deconz-rest-doc/getting_started/) I do not get either IP-Adress or PORT of any REST gateway.
So, could anyone help me with the installation process of the deCONZ REST API plugin https://github.com/dresden-elektronik/deconz-rest-plugin to Hassio? I am not very familar with installing plugins in Linux using ssh.
Thanks in advance!
