Need help choosing modules for 32-channel lighting control with Home Assistant

[admin]

1. i suggest you use multi A32Pro smart relay controller. multi controllers just connect to your same router, so that all controller can integrate to one home assistant account.
2. video tour about A32Pro:

KCSv3 new functions on A32Pro ESP32-S3 Home Automation Controller: https://youtu.be/6nDQ7tW21us

3. sure, if you download by KCS v3 firmware, just install mqtt broker on your home assistant , it's zero code for config, only need set the mqtt broker. here is KCS v3 online guide: https://www.kincony.com/how-to-use-kcsv3...board.html

4. we not suggest use extend relay way by i2c, because it's not a stable way, just use multi controller connect to router by ethernet cable is best way.

5. Server16 mainly use for install home assistant.
