C-Bus via MQTT and Matter Bridge

I have recently move from Hoobs (Homebridge out of the box) to Home Assistant (HA) and am serious impressed with the responsiveness and flexibility of this piece of free software.
Having found some excellent code from autosteve on Github (https://github.com/autoSteve/acMqtt) which when used inside your Nac or Shac will help expose your C-Bus GA's to HA, within HA add the Mosquitto MQTT broker change a few setting in the code in the NAC (Ip address, User name and password) Within the NAC program keywords to the devices you want exposed to HA (that took a long time ) and as if by magic you have these devices in your HA project.

Now comes the special bit IMHO, get google assistant to respond to your voice and quickly turn on your lights. A lot faster than GSH in Hoobs. Reading the documentation implies its local control.
Add an add on repository in HA from https://github.com/t0bst4r/home-assistant-addons for Home assistant matter hub. Add to each device that you want google to respond to a label (matter_exposed) read the documentation about adding this label, this process will also work for other products for example TUYA light and plug adaptors.
Whilst discussing HA if you have some TUYA devices which you want to easily control form C-Bus look at the section Automation and Scenes find linked entities, scroll to the bottom of the page and select the entities, I thought Node-Red was easy for this but this even simpler.

I will openly admit that this process is probably not viable as a commercial offering as you spend hours tinkering but for those who enjoy making their homes a little more special then it's worth the effort. But read the documentation provided and keep notes what you have done.

If anybody has been down this path I have a few unsolved issues Fan control being one I seem to get inconsistent results asking for my fans (3 speed via L5501RFCP) to turn on a Low or medium speed or even asking them to run at a percentage.

Next stage for me is to look at Spotify with my MRA if possible.
Any advice and pointers great fully received.
