Home Assistant versus Domoticz

Last Updated or created 2022-04-29

After many years Domoticz, tried Home Assistant … again.
Going to test this instance, running on a NUC, besides my production setup. Time will tell.

  • HACS installed.
  • Node-red connection
  • Zoneminder

I’ve got a RFXCOM connected to my domoticz, and i wanted to share my 433Mhz devices also in HA, so i configured ser2net.

On domoticz server

apt-get install ser2net

10001:raw:0:/dev/ttyUSB0:38400 NONE 1STOPBIT 8DATABITS max-connections=3
to /etc/ser2net.conf

Better is using by-id instead of ttyUSB

Find yours 
find /dev/ -type l -iname *RFX*



  • disable RFXCOM in hardware
  • stop domoticz
  • systemctl enable ser2net –now
  • check port with ss or netstat
  • start domoticz
  • and CHANGE hardware type from RFXCOM-USB to RFXCOM RFXtrx over lan (using port 10001)


Home Assistant

Add intergration “RFXTRX” , select LAN, input your domoticz IP and port 10001
Takes a while to populate the devices.

I’ve still have to find a way to add a second RFXCOM


IP Blocked fix (Locked myself out .. Remove contents in this file.)

Using SSH

➜  ~ find / | grep ip_ban   
➜  ~ vi /config/ip_bans.yaml
