Sonoff BLE - SwitchMan R5, S-Mate, S-Mate2

Sonoff BLE - SwitchMan R5, S-Mate, S-Mate2

Device Type: switch
Electrical Standard: global
Board: esp32
Difficulty: Plug-n-flash, 2/5

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
