Hi all!
I recently flashed my Shelly Plus Plug S with ESPHome (this topic).
My goal is to create a washing machine monitoring plug with all the logic on this system. The device should only provide the actual status to home assistant when integrated. The ESPHome YAML file is ready and works fine. (I can share the complete code if needed. 
)
The ESP monitors the power consumption and set the status from “Idle” to “Washing” and after this to “Ready”.
Here the Shelly BLU Door & Window comes into play. This sensor should be placed on the washing machine door. The Shelly Plus Plug S (with ESPHome on its ESP32 with Bluetooth) should connected directly to this sensor and receive the state updates. If the door is opened while the status is “Ready” the status should change back to “Idle”.
It is possible to connect the BLU Door & Window to Home Assistant and setup the logic there. But this is not what I want. Why? Aesthetics.
I spent many hours with ESPHome, the documentation, BLE logging apps but now it is time to ask for help.
- The Bluetooth Proxy is working (but not needed, I want to connect directly)
- The esp32_ble_tracker is also working
- The MAC address is known
- The Service UUID is known
- Many Service Characteristic UUIDs are known but not shure wich one is the right
- Firmware of the BLU Door & Window is updated via Shelly BLU Debug App to “20230826-195045/v1.0.9-rc1@1fb04462”
- ESPHome version is 2023.8.3
- I am not able to get the information from the sensor

then:
- logger.log: "Notifiy sensor updated"

on_notify:
then:
- logger.log: "Notifiy text-sensor updated"
Here is the log output if I open the configured sensor. I tried many different Service Characteristic UUIDs but the result is always the same.
