Hello,
Just in case someone might be interested, I automated our window blinds using the brilliant MQTT Cover platform. I designed a simple pcb for microcontroller (TinyS3), designed and made parts using 3d printer and finally connected the contraption to HA via MQTT. Altough bit noisy, it works well and can be easily automated using sun azimuth, weather etc. I can share more details if someone is interested.
Both lifting and tilting the blinds are driven using servos.
That’s pretty nice.
I’m guessing you used a different kind of motor than a servo. Those can turn at most 270 degrees. Probably a stepper?
Added after your reply…
TIL… Didn’t know they existed.
It is indeed a servo, a digital one. The one I use for lifting can be configured to act as a motor. The servo is able to report its position, so by polling I can even count revolutions, which I use to slow it down as it is approaching the limit sensor.
I chose this one as it has quite high torque, whis is a must since the blinds are actually quite heavy.
