ayufan's esphome custom components

This repository contains a collection of my custom components for ESPHome.

1. Usage

Use latest ESPHome (at least v1.18.0) with external components and add this to your .yaml definition:

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

2. Components

2.1. inode_ble

A component to support iNode.pl devices (energy meters and magnetometers).

2.1.1. Example

# the BT window is configured to be a small portion
# of interval to have a lot of time to handle WiFi
esp32_ble_tracker:
  scan_parameters:
    active: false
    interval: 288ms
    window: 144ms

# monitor RSSI and Power, Energy, and Battery Levels
# the `constant` defines a how many pulses are per unit
# ex.: 1500 pulses/kWh
# all sensors of inode_ble:
# - avg_w
# - avg_dm3
# - avg_raw
# - total_kwh
# - total_dm3
# - total_raw
# - battery_level
# - light_level
sensor:
  - platform: ble_rssi
    mac_address: 00:0b:57:36:df:51
    name: "Emeter RSSI"
    icon: mdi:wifi
    expire_after: 10min

  - platform: inode_ble
    mac_address: 00:0b:57:36:df:51
    constant: 1500
    avg_w:
      name: 'Emeter Power'
      expire_after: 10min
    total_kwh:
      name: 'Emeter Energy'
      expire_after: 10min
    battery_level:
      name: 'Emeter Battery Level'
      expire_after: 10min

2.2. eq3_v2

A component to support eQ-3 Radiator Thermostat Model N, and maybe also other ones.

This uses custom esp32_ble_clients implementation to support Bluetooth on ESP32.

2.2.1. Stability

This is quite challenging to ensure that BT works well with WiFi. Ideally it is preferred to run only eq3_v2 component on a single device, with all basic services. Usage of complex services, or complex logic can cause stability issues.

I also noticed that extensive logging (like in VERBOSE mode) during the BT connection cases WiFi to loose beacons, and results in disconnect.

2.2.2. Example

# time is required by `eq3_v2` to send
# an accurate time spec when requesting
# current state
time:
  - platform: sntp
    id: sntp_time

# refresh component state every 30mins,
# and announce it to Home Assistant MQTT
climate:
  - platform: eq3_v2
    id: office_eq3
    name: Office EQ3
    mac_address: 00:1A:22:12:5B:34
    update_interval: 30min
    valve: # optional, allows to see valve state in %
      name: Office EQ3 Valve State
      expire_after: 61min

# allow to force refresh component state
switch:
  - platform: template
    name: "Refresh Office EQ3"
    lambda: "return false;"
    turn_on_action:
      - component.update: office_eq3

2.3. tplink_plug

This plugin allows to emulate TPLink HS100/HS110 type of plug using LAN protocol with ESPHome. Especially useful where you want to use existing software that supports these type of plugs, but not others.

tplink_plug:
  plugs:
    voltage: my_voltage
    current: my_current
    total: my_total
    state: relay

# Example config for Gosund SP111

sensor:
  - id: my_daily_total
    platform: total_daily_energy
    name: "MK3S+ Daily Energy"
    power_id: my_power

  - platform: hlw8012
    sel_pin:
      number: GPIO12
      inverted: true
    cf_pin: GPIO05
    cf1_pin: GPIO04
    current:
      id: my_current
      name: "MK3S+ Current"
      expire_after: 1min
    voltage:
      id: my_voltage
      name: "MK3S+ Voltage"
      expire_after: 1min
    power:
      id: my_power
      name: "MK3S+ Power"
      expire_after: 1min
      filters:
        - multiply: 0.5
    energy:
      id: my_total
      name: "MK3S+ Energy"
      expire_after: 1min
      filters:
        - multiply: 0.5
    change_mode_every: 3
    update_interval: 15s
    voltage_divider: 748
    current_resistor: 0.0012

    # {"PowerSetCal":10085}

2.4. memory

Simple component that periodically prints free memory of node.

2.5. esp32_camera_web_server (upstreamed)

This component was removed as it is part of upstream esphome starting with version 2021.11: https://esphome.io/components/esp32_camera_web_server.html

• http://esphome:8080/
• http://esphome:8081/

esp32_camera_web_server:
  # define only what is needed
  # only a single stream is supported at a given time
  - port: 8080
    mode: stream
  - port: 8081
    mode: snapshot
