You got a mini tutorial on how you hooked up the home assistant to the icc?
I don't, but at a high level:
1. Add MQTT add-on to HA - configure it to "point" to ICC via ICC's IP address
2. Create sensors for the various MQTT topics you get back from ICC
I used an MQTT explorer on my computer to see what topics the inverter was sending out and added them to a list.
You can DM me for more info and I'll send you my configs.
I also have all of this data going to a DB (Influx + Grafana ) to make pretty graphs I don't look at a lot lol
