Sonoff BLE - SwitchMan R5, S-Mate, S-Mate2
 
- Following code will catch BLE advertisements from Sonoff SwitchMan R5, S-Mate & S-Mate2.
- code will generate HA events with data: device id, button pressed and kind of action
 
- Sonoff SwitchMan R5 will detect following actions: “short”, “double” & “long” press.
- Sonoff S-Mate:
- In DIP Switch position “Rocker” switch - generates event “short” on both transitions open-close & close-open.
- In position “Pulse” - only generates “short” on transition open-close contact, nothing more.
 
- Sonoff S-Mate2:
- When DIP switch in position “Momentary switch” - detects “short/double/long” events.
- In position “Rocker” switch - generates same event “short” on both transitions open-close & close-open.
 
Notes
- any ESP32 with BLE radio required to run BLE tracker
- BLE tracker not compatible with power_save_mode NONE
- events can see: Developer Tools → Events → Event to subscribe to: esphome.sonoff_ble → Start Listening
