Really cool idea, i’m back and forth between this and Automated roller blinds (IKEA Fridans/ESPHome/HA/MQTT/HomeKit/HomeBridge/REST @ 200cm wide) but i’m not sure which might be the better solution, they both seem from the videos/gifs to be of similar speed.
I’m concerned with the sound from both even for the other one i was considering using a forked esphome with TMC2209 drivers to make it silent, and maybe even figur eout a way to do sensorless endstop for closing the blind, but not sure if that was possible.
And for this one i’m worried as you mention that it’s got a continuous run issue with heat, had you considered maybe using a brushless motor?
Either way really cool project!
