Unlike Z-wave, Zigbee, etc., in Matter, when a simple binary (on/off) Matter wall switch is added to Home Assistant, it is always added as a “light” domain type. As a consequence, if you use one of these switches to control a device other than a light, you can’t use the Switch_As_X integration to change the domain to a Fan (my particular use case) or other appropriate type. It would be nice if the Switch_As_X integration could be expanded to allow Matter On/Off wall switches to also be shown as another domain type.
Or better yet, fix the matter inclusion of switches to not automatically assign them to lights.
There are a number of integrations to address these kind of issues… in case the powers that be decide the way Matter does things is fine.

Most wall switches identify themselves as Matter type 0x0100 which is an “On/Off Light”, so its correct for HomeAssistant to treat them as lights. Perhaps it would be better if they identified themselves as “On/Off Plug-in Unit” (Matter type 0x010A), but that’s not what the vendor chose, and thus the request to also handle “light” type devices using Switch_As_X
Yes, I went the template route to solve the issue, but Switch_As_X would have been much simpler.
