This is a small FUSE filesystem that exposes MQTT topics from a (remote) broker as a file tree. The content of exposed files is updated in realtime as soon as broker sends an update via MQTT subscription.
mqttfs depends only on fuse3. Once you have it installed, just
make
I don't care about any other platforms except Linux, so you are on your own.
Run it as any other FUSE filesystem binary providing a mountpoint. Optionally provide host and port of your MQTT broker as environment variables. Without any configuration it will try to connect to localhost on the standard port 1883:
MQTT_HOST=127.0.0.1 MQTT_PORT=1883 ./mqttfs /mount/point
Anything that you can imagine. I.e. try this, in the first terminal:
mkdir /tmp/mqttfs
MQTT_HOST=192.168.8.3 ./mqttfs /tmp/mqttfs
cd /tmp/mqttfs
python -m http.server 8000
In the second terminal:
curl http://localhost:8000/zigbee2mqtt/bridge/state
Yes.
