Tradfri to MQTT
This is a simple application that subscribes to a Tradfri gateway, and then publishes updates to MQTT.
It will push all known devices as
<prefix>/<device_type>/<device_id>/<property> = <value>
For example
ikea/plug/65539/powerFactor: 0
Currently this app supports:
- Plugs
- Lights
- Air purifiers
- Blinds
Note that motion detectors are not supported by Ikea at all at the moment.
The app also does not support scenes, and neither can you send commands to Ikea. Pull requests are welcome if people want to add this functionality.
Authenticating
When run the first time, you need to create an auth.json for this service, and re-use that every time. It seems like the gateway has a limited number of auth tokens it hands out, so others get logged out when you create new ones.
On the back of your gateway, you'll find a security code, you'll need this along side the IP or hostname to login.
To authenticate:
- From the source code, run
yarn auth <gateway_ip> <psk> - With docker, run
docker run ghcr.io/alexnederlof/tradfri-mqtt auth <gateway_ip> <psk>
Not the identity and psk it returns, and use that in the configuration below.
Configuration
The following items need to be configured.
| Key | Value | Required or default |
|---|---|---|
| MQTT_ADDRESS | IP or hostname of MQTT service | Required |
| MQTT_USER | MQTT Username | Default: No user/pass by default |
| MQTT_PASSWORD | MQTT Password | Default: No user/pass by default |
| MQTT_TOPIC_PREFIX | the prefix for MQTT Topics | tradfri |
| TRADFRI_GATEWAY | hostname or IP address of your Tradfri gateway | required |
| TRADFRI_IDENTITY | The identity generated by the gateway | required |
| TRADFRI_PSK | The PSK generated by the gateway | required |
On startup a .env file is also read in case you want to configure by file.
