In Apple Home through HomeKit Bridge

What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.

Entity	Shows up as	Note
`switch`	Switch or outlet
`sensor`	Sensor (temperature, humidity, air quality…)
`select`	Mode picker (as switches)

What people report

Solar Optimizer switches managed devices on surplus solar; recent PRs add water heaters, fans, selects, lights and buttons as controllable devices.
