Hey, I have a Shelly window/door sensor on my bifold door. It includes a lux and temperature sensor, which i’m using to close the blinds (luxaflex/hunter douglas) if the temperature exceeds a certain level along with a high light level.
In practice where I live it is easier to close the blinds based on the current outside temperature, but the window/door sensor makes a good second check. it also prevents the blinds from operating if the door is open!
