Home-Assistant Custom Components

Some of my custom components for home-assistant (HA). (http://www.home-assistant.io)

• Bluetooth Speaker - Play TTS through your bluetooth speaker connected to HA.
• DALI Light - Control your DALI lights
• Developer - Get notifications of HA Pull-Requests
• Electricity - Current tariff of a given electricity operator
• HomeGW Climate - Use an RF433Mhz weather logger as a climate sensor
• HomeGW Weather - Use an RF433Mhz weather station
• HomeGW Cover - Control your covers with just two relay's

Developer

As a Home Assistant developer, I like to keep a close eye into whats new (Pull Requests - PR). This component uses github API to find PR related to the components currently in use in the running HA.

HomeGW Climate

I'm currently using a cheap 433MHz Wireless sensor to monitor several rooms in the house.

Attached to my RPi3 running HA I've got an Arduino working as a gateway. The code running in the Arduino is provided here.

The serial sensor receives a payload similar to:

{"dev":"digoo","id":8,"ch":3,"batt":1,"temp":20,"hum":56,"raw":"0x8a0c8f38"}

Using the serial sensor platform and a MQTT binary sensor I've created the homegw_climate custom component that looks like a thermostat, but cannot act upon the HVAC.

The platform supports filtering by channel (ch) which is the only parameter the device provides configuration for.

HomeGW Weather

The weather station is by all means a copy of the climate platform (or the other way round). The same serial sensor is monitored, only the Wireless sensor is different.

Example configuration

sensor:
  - platform: serial
    serial_port:  /dev/tty.USB0
    baudrate: 115200

climate:
  - platform: homegw_climate
    name: quarto2
    serial_sensor: sensor.serial_sensor
    heating_sensor: binary_sensor.heating
    channel: 2

weather:
  - platform: homegw_weather
    name: backyard
    serial_sensor: sensor.serial_sensor

The filter_helper.py

This file provides a decorator class used in the homegw_climate and homegw_weather platforms. It has a dependency in the filter sensor which actually implements the filters.

HomeGW Cover

This is a cover platform on top of 2 relays exposed through MQTT. Each relays is closed for the duration in milliseconds publish to the control topic. delay_time indicates the time needed to go from 0% to 100% cover. Albeit the name, it is not related to the hardware supporting weather and climate components, for more information on this backend see home_mqtt.

Example configuration

- platform: home_mqtt
  covers:
    living_room:
      relay_up: 1
      relay_down: 2
      delay_time: 17000
    suite:
      relay_up: 3
      relay_down: 4
      delay_time: 17000
