Trådfri Alert

This simple web application serves as a webhook and flashes an IKEA Smart bulb. Use the webhook for any alert. This application is mainly designed for Raspberry Pi Zero W.

The blog post:

• Flashing Trådfri lights on Azure Alerts

Prerequisites

• IKEA Smart Bulb, remote and a gateway
• Raspberry Pi (or a computer)
• Installed libcoap
• ngrok
• python3

Setup

cp tradfri-sample.cfg tradfri.cfg

Update the values in the tradfri.cfg for your home environment.

Configure ngrok web interface to be accessible from other computers in your network:

echo "web_addr: 192.168.0.193:4040" >> ~/.ngrok2/ngrok.yml

Run the server and ngrok

nohup python3 server.py &
~/ngrok http 192.168.0.193:8000 -region eu > /dev/null &

On your computer navigate to ngrok web interface (192.168.0.193:4040 in my case), copy the public https address, try it with curl:

curl -d '' https://0ec6f40b50a6.eu.ngrok.io/

When done, register that webhook url in your alert setup.
