ESPHome components

A collection of my ESPHome components.

Please ⭐️ this repo if you find it useful.

If you have questions or problems with this components you can check this thread.

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

external_components:
  - source: github://myhomeiot/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 Client

BLE Client allow to read characteristics from devices. 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.

BLE Host

Used by BLE Client component.

BLE Gateway

BLE Gateway component will allow you to forward BLE Advertising data packets for external processing to Home Assistant or other systems.

If the heart of your Home Automation system is Home Assistant or another similar system and you use ESPHome devices to extend BLE coverage and process data from BLE sensors, you can dramatically decrease system complexity by remove all BLE data processing from ESPHome devices and forward raw BLE Advertising data to external components like Passive BLE Monitor.

Requirements:

• Passive BLE Monitor integration version 6.2 or later. Thanks @Ernst79
• ESPHome version 2022.1 or later

If you use ESPHome 2021.12 version or earlyer you need to make following changes in ESPHome esp32_ble_tracker component. In order to apply this PR you can use following ESPHome configuration (requires ESPHome 2021.11 or later):

external_components:
  - source: github://myhomeiot/esphome-components
  - source: github://pr#2854
    components: [esp32_ble_tracker]

ESPHome configuration example

Note: This example use event, you can use direct ble_monitor.parse_data service call

ble_gateway:
  devices:
    - mac_address: 01:23:45:67:89:AB
    - mac_address: !secret lywsd03mmc_mac
  on_ble_advertise:
    then:
      homeassistant.event:
        event: esphome.on_ble_advertise
        data:
          packet: !lambda return packet;

Home Assistant Passive BLE Monitor configuration example

Note: Remove automation if you use direct ble_monitor.parse_data service call

ble_monitor:
  discovery: false
  restore_state: true
  decimals: 1
  period: 300
  devices:
    - name: Living Room Thermo
      mac: 01:23:45:67:89:AB
    - name: Bedroom Thermo
      mac: !secret lywsd03mmc_mac

automation:
  - alias: ESPHome BLE Advertise
    mode: queued
    trigger:
      - platform: event
        event_type: esphome.on_ble_advertise
    action:
      - service: ble_monitor.parse_data
        data:
          packet: "{{ trigger.event.data.packet }}"

Advanced configuration where ESPHome devices gets MAC addresses from Passive BLE Monitor configuration

Note: Be sure that you turn on the input_boolean.settings_ble_gateway if you want to receive BLE packets from BLE Gateway's.

Important note: New device address will be populated to ESPHome devices only after Passive BLE Monitor receives first BLE packet and creates entities for it. If in your configuration you don't have BLE stick and you have only ESPHome devices you can use one of the following methods:

1. Add this device MAC address manually into the input_text.settings_ble_gateway_add_device. After Passive BLE Monitor creates entities for new device, you can remove address.
2. Enable discovery for Passive BLE Monitor and ESPHome BLE Gateway input_boolean.settings_ble_gateway_discovery. After required devices will be discovered turn off discovery options (for Passive BLE Monitor and ESPHome BLE Gateway) and clean up unneeded devices that got detected if any.
