Configs for a esp32-based ESPHome Bluetooth Proxy that can also control an AutoSlide sliding door opener over its modbus pin header (marked "RS485"), by way of an additional RS485-to-TTL converter module.
Once discovered in Home Assistant, you can remotely trigger sensors & buttons that come with the kit, observe the state of the door opeining, and change its mode (Auto/Pet/Stacker/Security).
My autoslide has a "V2" control board and the unit was manufactured in 2022.
I had to remove both the external cover and the interior electronics cover to expose its RS485 pin header (top right corner), and then wirewrapped its three left-most pins to 5 inches of 30AWG going to the RS485 module.
- pin 1: B (D-)
- pin 2: A (D+)
- pin 3: ground
- pin 4: 12V (I don't use this one & shorting it to ground will reset the autoslide!)
I could not get this working with the "automatic" flow-controlling modules, they would corrupt the initial bytes of the reply.
A simpler module with DE & RE pins (hardware flow control) worked fine. Bridge them together with some solder and hook up one pin to a GPIO on the ESP32.
you will have to play with flip flopping the TX/RX and A/B connections until you get both correct. the labels on any particular module don't inherently mean much without a full text description or maybe a direction arrow in their product picture.
you can set logs to VERBOSE to see individual send/reply bytes, the autoslide PDF linked in the yaml has examples of what you should be seeing.
if your module has RX/TX leds, seeing both flash at the same time is also a good sign you've got the wiring correct.
fill in network.yaml.sample and remove the .sample extension
for first run, plug in the esp32 over USB and run
pip3 install esphome
esphome run sliding_door_controller.yaml
once its flashed and successfully associated to wifi, run or logs will use OTA to manage the device.
