Comfort2MQTT with Home Assistant Part1 - setup - slychiu - 11-26-2024

This topic is a step-b-step  by step guide to installing the Comfort2MQTT Add-on with Home Assistant on Raspberry Pi for Novices (like myself). Many thanks to koochyrat and Ingo for their efforts in developing this add-on as an Open Source project.
This will be a closed topic, no replies allowed as it should be for instructions only. Start a new topic for questions.

My set up is;
  1. Raspberry Pi 5 8GB (raspberry pi 4 will also work - in fact it may be better as it requires less current). Home assistant Green or Yellow also works
  2. MicroSD card 16GB or above (8GB may work but not tested).
  3. MicroSD card Reader for your PC if it does not have a built in SD card slot
  4. USB Type C Power Supply 5V / 5A
  5. HDMI Monitor (Optional)
  6. Micro-HDMI to HDMI cable for Monitor
  7. CM9001-ULT with UCM/ETH03 or  ETH03 Plugin on CM9001 PCB


Raspberry Pi with 2 LAN Port, 4 USB-A, 1 USB C port, Micro HDMI port, Micro-SD card slot. You need a USB power supply with Type C connector able to supply 5A.
A HDMI Monitor would be useful during the setup as it allows you to see the progress of installing the OS. For this you need a Micro HDMI to HDMI cable. The monitor will notbe needed in operation after setup. 

Note:
We have tested with Raspberry Pi4 which requires less current. It works just as well
Comfort: UCM/ETH03 or ETH03 submodule plugged in on CM9001 is required. There are 2 ports available to connect to Comfort which cn be seen in Comfort Server Manager. see http://www.comfortforums.com/forum113/3695.html

It is recommended that the 2nd port (default 1002) is used for Home Assistant to log in nd Port 1 (port 1001) be used for Comfigurator. The 2nd Port time out should be set to 0 so that it does not log out after a few minutes

Download RPI Imager from https://www.raspberrypi.com/software/. This allows you to format the Micro SD card and install the Home Assistant OS.
  • Insert the Micro SD card into the MicroSD Card reader to yourPC
  • Run the RPI Imager software
  • select Raspbery Pi device = Raspberry Pi5,Operating System =  Other Automation Operating systems  > Home Assistant OS (13.2) is the current version at this time), and select the SD Drive detected in Storage 


  • Press start and wait for the OS to be written and verified which takes about  minutes
  • when completed with no errors, remove the SD card from the reader and insert into the RPi. Note that the SD card will not be detected or readable on your PC anymore. It can be rewritten by RPI imager if needed

  • Insert the Micro SD card into the slot at the back of the Rpi
  • Connect the HDMI cable from the Monitor to the Micro HDMI connector on RPi (optional - this allows you to see the booting up sequence). HDMIshould not be required after this
  • Connect the USB power supply to the RPi Type C Connector, and turn on power.
  • The LED on RPi should initially be Red and will change to green, flashing as the OS is installed
  • The monitor will show many lines of text during the installation. This will take many minutes.
  • when complete, the monitor will show the Home assistant logo, the IP addresses, S version 13.2 Home assistant Core Date, Home Assistant URL http://homeassistant.local.8123 and Observer URL http://homeassistant.local.8123

Press Create My Smart Home. The next screen will start the initialisation, which may take up to 20 minutes.





If the boot-up keeps resetting as seen on the  monitor, this may be dueto using a power supply that does not suppy enough current, or a bad Micro SD card. Use a reputable brand of Micro SD card with at least 16 GB capacity

If you have any problem with the SD card not installing Home Assistant, check that the Power supply is sufficent. if the power source is a USB adaptor. make sure that the current is sufficient to support the Raspberry PI. For RPi5, the specs is 5V / 5A but you may need more current
