Automating skylights with blinds to block direct sun
Automating skylights with blinds to block direct sun
Looking for a solution on how to determine when to close and open skylight blinds. I can just do hours of the day but would like it to be a bit more intelligent.
Anyone looked at using something like the math used for solar panels? I was thinking that when max solar power was generated in the summer that is when they are closed to keep heat out.
Ideas?

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!
Out of curiosity: how long does the battery last on those devices?
I’ve had this one (it’s the Wifi version not Bluetooth) for about four months and it claims that the battery is at 81%. I’ve not owned it long enough to say if that is a linear or exponential (or totally made up) value.
Wow, I thought that the WiFi version would consume way more. Thanks!
I expect it varies depending on how often you open the door, what firmware it’s on, whether it’s MQTT or something else etc etc.
