Thanks for that, they are a very interesting product arnt they? Problem is that they are cloud controlled i really dont want to run any of my devices that way if it can be avoided.
I'd seriously think about whether switchbot is the way to go. From personal experience, and from what's posted online, their support is shocking. Lots of issues with the curtain device too. Of course, as always, YMMV.
Im certain that they do and ther are fine in a modern house but will look wrong in an 1898 period house, im trying to find out the dimensions of the track, without buying one to see if i can cut a a pole, in half ang glue it to the front of the track.
Think ive come up with a solution. 2 lead screws 1 left hand one right hand, joined in the middle and driven from one end with a stepper motor controlled by and arduino esp2866. ill keep you posted.
the parts have mostly arrived and ive spent the last 2 weeks leaning CAD and 3 d printing to print the motor & Bearing mounts photos to follow shortly but it seems to work mechanically, i just need to sort the electronics out.
Heres some general pics showing the original pole mount and my 3d prototype evolution im working on the drive / bearing mount now, its still printing, but considering id never printed anything or used CAD before, im quite chuffed with myself.
