No.20. Automatically open and close curtains or blinds
You can use a LightwaveRF LW821 In-line relay to operate many types of curtain or blind motors. This allows them to be opened and closed using the App and/or a wireless On/Off/Stop switch. You can also go one step further and set a timer that will automatically open or close the curtains or blinds at dawn or dusk. So you can now be woken up naturally every day, as the bright sunlight streams into your bedroom*. Which is a good thing. Obviously.
*Please note offer of bright sunlight is not always applicable to UK based customers.
