It would be great if there was an RF receiver that can connect also to WIFI.
The device would react to the RF controller buttons and could be used to turn other WIFI devices on and off. Currently these have to be controlled using the Ewelink software on a phone. However, with the RF controller, that controller can be used by everybody to switch various scenes in a room. For example 1 - Main lighting , 2 - Watching movies, 3 etc.
This would also be very useful for guests who wouldn't have the app installed.
Also for Air B&B locations.
Multiple controllers should be able to be configured for various locations around the home.
