raspyrfm integration adds support for cheap RC 433 MHz outlets via one of the supported gateways.
Initially, this integration was created to support the Simple Solutions
ConnAir gateway which has been discontinued. There are custom alternatives that reimplemented the protocol used by the ConnAir though like this ConnAir emulator which can be used in conjunction with the RaspyRFM-II RC module for a Raspberry Pi.
Other vendors of 433 MHz RC outlets have also created gateways that use a very similar protocol and can also be used with this integration like the Intertechno ITGW-433 LAN Gateway.

List of switches that can be controlled with this gateway.
Have a look at the underlying library raspyrfm-client to check what gateways and control units (outlets) are supported.
Depending on the control unit the channel configuration can have varying formats. Have a look at the underlying library raspyrfm-client to find out about a specific model.
Initially, the state of a switch is unknown. When the switch is turned on or off (via frontend) the state is known and will be shown in the frontend.
Note that due to the way those cheap RC units work it is not possible to query their current state. Therefore the only way to preserve a consistent state within Home Assistant is to only use Home Assistant as the controller.
