I was accidentally locked out of home again, and I had to call a professional to open the lock.
But if someone was home, they could have just turned the knob of the door from inside. There’s a device that can do that? It needs to do 3 full turns and it requires a bit of force to do that (armored door with iron bars that slide in every direction, so it has a big inertia to start)
I saw a ready solution on a store, the iseo x1r, but that costs 1000 euro + another 200 for the gateway (not mandatory but otherwise it uses proprietary Bluetooth protocol and so it can’t talk with HA
My guess is that a servo will probably be a bit too weak for that. They’ll propablyeneed a stepper motor.
Gears !!!
Read that with elongated syllables, sparkles and reverb
What kind of servo would you use with gears and still enable 3 x 360 degree revolution?
Oopsie! You’re right. No way.
Depends on the lock being actuated and the torque of the servo, I have some that can do 4.4 N-m.

A stepper motor would also work for sure.
TIL about high torque servos.
