Hello Lemmings, Hope you guys are doing well.
Objective: Open the door automatically through HomeAssistant
My Plan:
-
Use an ESP32 and flash ESPhome. Wire up Servo Motor (SG90) with ESP32. Tie a thread on between the Servo Motor Arm and the physical latch (physical latch that I can pull to unlock the door) such that when the servo motor turns from -100 to +100, the latch is being pulled to cause the door to be unlocked.
-
I am planning to power this using AA Cells + DC DC Boost convertor.
Issue:
- How do I mount the Servo Motor on the door?
- Is there any other (read better) way to achieve the same result?
- Would you recommend any power source other than AA Cells?
Image for reference:
The latch has a keychain-like loop where the thread is tied. To unlock the door manually, I pull the latch towards right (---->) . This action is planned to be automated by Servo Motor.
