anavid

Standalone daemon process for controlling ANAVI Light pHAT over MQTT

Installation

• Install Hassbian on Raspberry Pi

• Run the command below and enable I2C from Interfacing Options:

sudo raspi-config

• Install mosquitto, doxygen, wiringpi, piGPIO and OpenSSL:

sudo apt-get update
sudo apt-get install -y mosquitto mosquitto-clients wiringpi pigpio libssl-dev doxygen

• Enable anonymous connection to the MQTT broker by editting the following setting in /etc/mosquitto/mosquitto.conf:

allow_anonymous true

• Start Mosquitto and enable its automatic launch at boot:

sudo systemctl enable mosquitto.service
sudo systemctl start mosquitto.service

• Install Paho (library for MQTT clients)

cd ~
git clone https://github.com/eclipse/paho.mqtt.c.git
cd paho.mqtt.c
make html
make
sudo make install

• Build and install anavid

cd ~
git clone https://github.com/AnaviTechnology/anavid.git
cd anavid
make
sudo make install

• Create configuration file and adjust the settings:

sudo cp config/anavilightphat.ini /etc/anavilight.ini

• Start the system service

sudo systemctl start anavi

• Retrieve device ID

anavid -m

• Replace DEVICEID and add the following lines to configuration.yaml

# MQTT Broker (aka Mosquitto)
mqtt:
  discovery: true
  broker: hassbian.local
  port: 1883

# ANAVI Light pHAT
light:
  - platform: mqtt_json
    name: "ANAVI Light pHAT"
    command_topic: "DEVICEID/action/rgbled"
    brightness: true
    rgb: true

• Run the following command to restart Home Assistant and reload configurations:

sudo systemctl restart home-assistant@homeassistant.service

Integration with Amazon Echo and Alexa

• Add the following settings to your configuration.yaml:

emulated_hue:
  type: alexa
  expose_by_default: true

• Run the following command to restart Home Assistant and reload configurations:

sudo systemctl restart home-assistant@homeassistant.service

• Ask alexa to discover new devices

• Say "Alexa, turn on ANAVI Light pHAT" to turn on the lights

• Say "Alexa, turn off ANAVI Light pHAT" to turn off the lights

MQTT Commands

NOTE: Replace with the actual machine ID!

• Change the colors of the 12V RGB LED strip to red:

mosquitto_pub -h 192.168.4.250 -d -p 1883 -t "<replace-with-your-device-id>/action/rgbled" -m "{ \"state\": \"ON\", \"color\": { \"r\":255, \"g\":0, \"b\":0 } }"

• Change the colors of the 12V RGB LED strip to yellow:

mosquitto_pub -h 192.168.4.250 -d -p 1883 -t "<replace-with-your-device-id>/action/rgbled" -m "{ \"state\": \"ON\", \"color\": { \"r\":200, \"g\":200, \"b\":0 } }"

• Set the 12V RGB LED strip to full brightness:

mosquitto_pub -h 192.168.4.250 -d -p 1883 -t "<replace-with-your-device-id>/action/rgbled" -m "{ \"state\": \"ON\", \"color\": { \"r\":255, \"g\":255, \"b\":255 } }"

• Turn off the 12V RGB LED strip:

mosquitto_pub -h 192.168.4.250 -d -p 1883 -t "<replace-with-your-device-id>/action/rgbled" -m "{ \"state\": \"OFF\" }"
