setup conbee 2 on pi (zero)

because it took a lot of time to figure out I keep it here

Tech

Raspberry Pi Zero with Raspbian Conbee2 Zigbee dongle USB->Mini USB Adapter (with OTG?)

Power

First Pi did not work. Another USB cable Power Adapter worked. I am using a USB->Mini adapter with OTG (not sure if that is needed). The original power supply supplied only 0.2A

Install deConz

Install deConz like is described on https://phoscon.de/en/conbee/

Desktop UI

Even if you are running the pi without Monitor you need to have the Desktop enabled :(

$ raspi-config

In the same screen you can enable VNC if you want it (I ended up not needing it)

Port

run service with

sudo systemctl enable deconz

It will run on part 80. For me it did not work. Change the port with

sudo systemctl edit deconz

And add this

User=pi
# /etc/systemd/system/deconz.service.d/override.conf
[Service]
ExecStart=
ExecStart=/usr/bin/deCONZ -platform minimal --http-port=8080 --ws-port=8081 --auto-connect=1 --dbg-error=1

I am not sure the first line (pi is the user) is necessary but I copied it from somewhere and I am not going to do experiments now that it works ;D
