ESPHome components

A collection of my ESPHome components.

To use this repository you should confugure it inside your yaml-configuration:

external_components:
  - source: github://dvb6666/esphome-components

or download component into custom_components folder (you can use another name) and add following lines to your yaml-configuration:

external_components:
  - source: custom_components

You can take a look at samples of usage of those components in examples folder.

BLE Client2

Copy of myhomeiot BLE Client that allows:

• To read set of characteristics from device at the same connection.
• To write characteristics (when option value presents). You can skip executing Write-command when data array is empty by setting option skip_empty to true. Examples:

      - service_uuid: '0000fff0-0000-1000-8000-00805f9b34fb'
        characteristic_uuid: '0000fff1-0000-1000-8000-00805f9b34fb'
        value: [0xFD, 0x37, 0x00, 0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0xCB]
        
      - service_uuid: '0000fff0-0000-1000-8000-00805f9b34fb'
        characteristic_uuid: '0000fff1-0000-1000-8000-00805f9b34fb'
        skip_empty: true
        value: !lambda |-
          return {0xFD, 0x37, 0x00, 0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0xCB};

• To subscribe for notifies (when option notify set to true). Example:

      - service_uuid: '0000fff0-0000-1000-8000-00805f9b34fb'
        characteristic_uuid: '0000fff4-0000-1000-8000-00805f9b34fb'
        notify: true

• To force update BLE-client with action myhomeiot_ble_client2.force_update or method force_update() from lambda. Example:

button:
  - platform: template
    name: "Force Update"
    on_press:
      - myhomeiot_ble_client2.force_update:
          id: my_ble_client
      # - lambda: |-
      #     id(my_ble_client).force_update(); // same with lambda

myhomeiot_ble_client2:
  - mac_address: "01:23:45:67:89:AB"
    id: my_ble_client

• To delay service launching with option or lambda delay. Example:

      - service_uuid: '180F'
        characteristic_uuid: '2A19'
        delay: 3s
        # delay: !lambda |-
        #   return 3000; // same with lambda in microseconds

Difference from build-in ESPHome BLE Client:

• Always disconnects from device after reading characteristic, this will allow to save device battery. You can specify update_interval, defaults to 60min.
• Uses lambda for parsing and extracting data into specific sensors make this component very flexible and useful for prototyping.
• There is no limit to the number of BLE Clients used (build-in BLE Client has limit of 3 instances). This component uses BLE Host component which you should count as one instance of build-in BLE Client. All BLE clients are processed sequentially inside the host component at time when they was detected and update interval reached.

ESPHome configuration example

Note: This example needs three template sensors with id: battery_level, tx_power, link_loss

esp32_ble_tracker:
myhomeiot_ble_host:
myhomeiot_ble_client2:
  - mac_address: "01:23:45:67:89:AB"
    update_interval: 300sec
    services:
      - service_uuid: '180F'
        characteristic_uuid: '2A19'
      - service_uuid: '1804'
        characteristic_uuid: '2A07'
      - service_uuid: '1803'
        characteristic_uuid: '2A06'
    on_value:
      then:
        lambda: |-
          ESP_LOGD("M1", "Received [%d] for service %d", x[0], service);
          if (service==1) id(battery_level).publish_state(x[0]);
          else if (service==2) id(tx_power).publish_state(x[0]);
          else if (service==3) id(link_loss).publish_state(x[0]);

MCLH 09 Gateway

Component-helper for control any quantity of MCLH-09 flower-sensors with BLE Client2. For every MCLH-09 device it will create sensors: battery level, temperature, soil, light, rssi.

ESPHome configuration example

esp32_ble_tracker:
myhomeiot_ble_host:
mclh_09_gateway:
  interval: 10min
  error_counting: true
  raw_soil: false
  mac_address:
    - "00:00:00:11:11:11"
    - "00:00:00:22:22:22"
    - "00:00:00:33:33:33"
    - "00:00:00:44:44:44"

MCLH 09 MQTT Gateway

Same as MCLH 09 Gateway, but for MQTT. Config example.

More configuration examples you can find in examples folder.
