Zigbee: Setup zigbee2mqtt with usbstick conbee II & influxdb on a raspberry pi

Just a short walkthrough of all steps which are necessary:

1.) insert the usbstick and check if this special device is there: /dev/ttyACM0 

if this device is not showing up, it might be, that your kernel does not support usbserial. In my case i had to downgrade from ubuntu server 21.10 to 21.04.

2.) follow these steps:


apt-get install -y nodejs git make g++ gcc npm
git clone /opt/zigbee2mqtt
cd /opt/zigbee2mqtt
npm ci

if you get 

prebuild-install WARN install EACCES: permission denied, access '/root/.npm/_cacache'

then you should not use root for running this command.

cd /opt/zigbee2mqtt
chown -R ubuntu node_modules
rm node_modules/*
npm ci

3.) install mqtt 

apt install mosquitto mosquitto-clients

4.) add to /etc/mosquitto/mosqitto.conf the line

listener 1883

and restart mosquitto (systemctl restart mosquitto)


5.) then start the zigbee2mqtt:

cd /opt/zigbee2mqtt
npm start

 if you get

Zigbee2MQTT:error 2021-11-06 09:05:23: Error: Error while opening serialport 'Error: Error: No such device or address, cannot open /dev/ttyACM0' 

then you did not really check step 1.): please check that /dev/ttyACM0 is missing - if yes: for me the kernel module (to list: lsmod) usbserial was missing. It seems, that ubuntu missed that on 21.10 - so i reinstalled 21.04....

if you get

zigbee2MQTT:error 2021-11-06 14:54:11: MQTT failed to connect: connect ECONNREFUSED

 then you did not get mosquitto running. Check with systemctl status mosquitto and follow step 3 and 4.

6.) configure telegraf, so that the data from mosquitto is transferred to influxdb. So you have to add to telegraf.conf:


   servers = ["tcp://"]
   topics = [
   data_format = "json"

   urls = ["unix:///var/run/influxdb/influxdb.sock"]
   username = "admin"
   password = "XXXXX"

7.) add this user to influxdb:


influx -ssl -unsafeSsl (only influx if you have not enabled SSL)

create user admin with password 'XXXXXXX' with all privileges

8.) if you have joined a device this the zigbee2mqtt, then you have to give a friendy name inside /opt/zigbee2mqtt/data/configuration.yaml

   friendly_name: 'sensor/t1'
