I have a small HA system running without issue. One of the devices that is controlled is a wall switch, well kinda… I wired the wall switch as the controller for some device that i was able to cram the device into electrical box with the switch. The device controls the light either via HA or by flipping the wall switch on/off. Works fine.
I would like to expand the system and cannot know, in advance, if I will be able to hide a device in a switch’s electrical box. So, my question is simply this: Would you please either provide me with a list of switch devices, or simply point me to a page where they are listed, that can be used both manually and via HA to control a light. Ideally, such devices would be usable locally only, i.e., not having to register said device with some website somewhere.
