Just want to share instruction on my hardware modification to AM43 blinds engine. This mod replaces BLE module inside device with ESP8266 module allowing to control blinds using MQTT.
All projects that I saw used discrete devices to bridge MQTT/REST -> Wi-Fi -> BLE, and since I have many problems with BLE module range and response times the only way for me was to completely replace BLE module.
Also you can add some rubber sound-vibration damping material around motor and gearbox to reduce noise. This improves device acoustics a lot! After mod it’s almost unnoticeable at night.
