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;

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

My set up is;
- 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
- MicroSD card 16GB or above (8GB may work but not tested).
- MicroSD card Reader for your PC if it does not have a built in SD card slot
- USB Type C Power Supply 5V / 5A
- HDMI Monitor (Optional)
- Micro-HDMI to HDMI cable for Monitor
- CM9001-ULT with UCM/ETH03 or ETH03 Plugin on CM9001 PCB
