AXA Remote
The AXA Remote is a rigid chain actuator driven electronic window opener that is mounted in the window frame. It comes with an infrared remote control but can also be controlled using serial commands.

The AXA Remote component for ESPHome lets you control an AXA Remote window opener using these serial commands.
The component features:
- Open/Stop/Close the window
- Move window to a given position
- Calibrate the open/close timings
- Use remote control simultaneously
PCB
A custom PCB is developed that fits in the battery compartment of the AXA Remote and can control up to two window openers. Only minor modifications to the battery compartment are needed.

The PCB is powered from the AXA Remote power supply and uses an ESP32 which is pre-loaded with the required ESPHome firmware. The firmware supports the open Improv Wi-Fi standard via BLE and a captive portal to easily setup your local Wi-Fi network credentials.
Additionally a Light-Dependent Resistor (LDR) can be installed to add a light sensor to the board.
