My patio doors have the venetian blinds built in between the glass of the double glazing (no dusting needed

)
They are made by Somfy and are fully automatic up and down. Ie, press "down" and they lower until you release or press & hold "down" for a second then release and they lower all the way & vice versa up. They were supplied and installed by the supplier of the doors but the blind motors etc are from Somfy & controlled by RF remote as opposed to IR.
I have my home automation set to send the RF codes to close them and open them at various times and turn on/off various lights to give the impression of someone home.
