This is a simple python service which subscribes to two different MQTT topics (https://nanomq.io) and then combines the data to create a new virtual state like human presence detected in a room.
One topic provides data fed in by a noise sensor which is attached to a RPI. It uses the service https://github.com/arnonuem/noise-sniffer.
The other topic provides everything which my Philipps Hue-Bridge knows. This was achieved using the excellent library https://github.com/trickeydan/hue2mqtt-python.
Once the virtual state goes into the condition of no human presence a 10 minute timer is started which, when not interrupted, will turn off the lamps in the living room.
Clone the repo and install Paho MQTT dependency.
sudo pip3 install paho-mqtt
Script can be manually started using:
python3 /path/to/script
The script will run forever.
This is optional but recommended :)
In /etc/systemd/system/ create a file like smart-hue.service.
Add the following content:
[Unit]
Description=Run smart-hue
After=default.target
[Service]
Type=simple
User=someuser
Group=someuser
ExecStart=python3 /home/someuser/py-smart-hue/smart-hue.py
[Install]
WantedBy=default.target
sudo systemctl start|stop|status smart-hue.service
