I was finally able to finish the last automated window treatment in my home. This one was a bit trickier than the rest of the house. First thing I needed to do was have an electrician add outlet on the right hand side of my patio door. I was then able to combine a Zemismart Zigbee curtain rail , to move the blinds left and right. And a Soma Tilt 2, to rotate the blinds open and closed.
A raspberry Pi zero W ,running the Soma Connect software, is used to control the Soma Tilt device.
I was able to add in the commands needed for the Soma Tilt device to a Zemismart Zigbee Shade Driver. I have checks in place to make sure the Soma device receives the message to rotate and also a slight delay to make sure the blinds start turning before the rail starts to slide open. Also the blinds rotate to "0" at a different range depending on how far open "left to right" the blinds are. This prevents them from over tightening and throwing off the calibration. Each time the blinds change level/position the blinds rotate to 100% and when they stop they rotate to "0" depending on the open level/position.
I am about to move to a new home with vertical blinds on 10 of the windows.
I have been trying to work out how to tilt the blinds from open to closed, I now have a way!
I don’t think I need to actually pull the blinds all the way back just tilt.
I like the idea of being able to track how bright it is outside and inside each room an tweak the blinds throughout the day to maximise sun coming in or tilt against the sun to allow light in but not direct sun in the summer.
Looking forward to this project thanks for all you have done
