I need Help to use esp32 to Control Yeelight Candla BLE Lamp with MQTT / HomeAssisant #674

Open Titanius opened 4 years ago

Titanius commented 4 years ago

to the best programmers - it is possible to do this with an ESP32

Use a esp32 to Control Yeelight Candela BLE Lamp. On / Off / brightness

Links i found: https://github.com/praschak/candelapy https://github.com/rytilahti/python-yeelightbt

I have my Candela in HomeAssistant, but the connection isn't stable. I just thought as you, to use esp32... I'm using ESPHome ble hub to read Mi sensors, maybe it is possible to connect Yeelight Candela similiar to Yeelight night lamp?

MiguelAngelLV commented 2 years ago

I have the same problem. I have a ESP32 to read my xiaomi temperature sensor and I want use it to control the candela too.

Please see https://github.com/dentra/esphome-components/tree/master/components/miot_ylai003, does this work for you? Possibly related to https://github.com/esphome/feature-requests/issues/1230

MiguelAngelLV commented 2 years ago

@nagyrobi that is BLE remote control. We need that esp32 control the light, not control the esp32 with the light.

Here's some informations about OpenMQTTGateway control the Yeelight BLE Candela: https://community.openmqttgateway.com/t/feature-request-support-for-xiaomi-yeelight-ble-candela/1898/1

I have exactly the same requirements with @MiguelAngelLV , I have a Mi sensor and a Yeelight Candela :)

I have some experiment and on/off is supported now, here's my config:

ble_client:
  - mac_address: XX:XX:XX:XX:XX:XX
    id: yeelight_ms
    on_connect:
      then:
        - script.execute: yeelight_pair

switch:
  - platform: template
    id: yeelight_candela
    name: "Yeelight Candela"
    turn_on_action:
      - script.execute: yeelight_on
    turn_off_action:
      - script.execute: yeelight_off

script:
  - id: yeelight_on
    then:
      - ble_client.ble_write:
          id: yeelight_ms
          service_uuid: FE87
          characteristic_uuid: AA7D3F34-2D4F-41E0-807F-52FBF8CF7443
          value: [0x43, 0x40, 0x01]
  - id: yeelight_off
    then:
      - ble_client.ble_write:
          id: yeelight_ms
          service_uuid: FE87
          characteristic_uuid: AA7D3F34-2D4F-41E0-807F-52FBF8CF7443
          value: [0x43, 0x40, 0x02]
  - id: yeelight_pair
    then:
      - delay: 3s
      - script.execute: yeelight_off
      - delay: 0.5s
      - script.execute: yeelight_on
      - delay: 0.5s
      - ble_client.ble_write:
          id: yeelight_ms
          service_uuid: FE87
          characteristic_uuid: AA7D3F34-2D4F-41E0-807F-52FBF8CF7443
          value: [0x43, 0x67, 0x02] # enable pulse mode

Without the pairing process, the ble connection will be disconnected by candela every 30s, then the on/off command will have to connect at first everytime, the whole process cost about 2s.

The config above solved the pairing issue, the long connection keep the trigger command in low lagency.

Need to upload config twice. First time keep - script.execute: yeelight_pair this line, when candela connected, it will came into pair mode, rotate the candela to complete the pair process. Second time, remove - script.execute: yeelight_pair, and upload again.

The brightness command is [0x43, 0x42, 0x00~0xFF], I'm not very familiar with esphome config, if anyone knows how, please let me know :)

quite complicated, but it works for me, with status update notify.

hope someone can combine it to a single c++ component.
