[crhan]

Could you add the new models to the correct line (equal device type) of the array?

This change also requires the devices to be added in xiaomi_aqara component to correctly add the devices to home assistant. If not, this only remove the error messages for not recognized devices in the logs. I tested the integration in my environment with the devices. home-assistant/core#37985

I try add the models to init.py. but still can not find the wall switch in the ui of homeassistant.

Does this add support for Aqara Switch D1 3 gang as well - "lumi.switch.l3acn3"?

Thanks.

[syssi]

No.

Would it be possible to add this support?
