Oh I wasn’t finished.
I have learned so much on these forums, and can rarely contribute any help because 99% of the people here can sweep me under the rug with their knowledge. I believe in ‘pay it forward’ so here is my contribution :
I took a blind down and disassembled it to get measurements.
The bare minimum width is 11”
The motor drive unit is 10” wide
So, an IKEA blind can fit in your 12” space, and is Zigbee.
The minimum width IKEA sells is 23” and it sells for $129.99
I own 12 of these and had to cut about 5 to fit my windows. The blinds are not difficult to modify.
So, for about $150.00 with tax you will have what you need.
