-- [Climate](../climate/) (beta)
-- [Cover](../cover/)
-- [Fan](../fan/)
-- [Light](../light/)
-- [Lock](../lock/)
-- [Number](../number/) (i.e. analog output)

-- [Sensor](../sensor/)
-- [Siren](../siren/)
-- [Switch](../switch/)

 There is also support for Zigbee grouping of lights, switches, and fans (i.e. support for commanding device groups as entities). At least two entities must be added to a Zigbee group in the ZHA integration before the group entity is created. As well as support for [binding and unbinding (i.e. bind a remote to a lightbulb or group)](#binding-and-unbinding).
