This is 1wire (onewire) owfs gateway to MQTT broker written in python. It takes information from files on mounted fuse.OWFS filesystem and sending all collected information to MQTT in json. Tested on rapsbian pi 10.1, but it must works well on other systems with python 2.7

Requirements: apt-get install python python-paho-mqtt python-ConfigParser python-setproctitle installed and mounted owfs, for example:

root@raspberrypi:~/1wire2mqtt# ls /mnt/1wire/

1D.6A9306000000 26.DA2F71010000 28.0425260A0000 28.48B3010B0000 28.61CC260A0000 28.BF16270A0000 alarm bus.1 settings simultaneous statistics structure system uncached

Configuration

read 1wire2mqtt.cfg comments You can add all needed file names to parse in case "filename" : "value" from owfs_path.

For example:

root@raspberrypi:~/1wire2mqtt# ls /mnt/1wire/28.BF16270A0000/

address crc8 family id locator r_address r_locator temperature temperature11 temperature9 templow type alias errata fasttemp latesttemp power r_id scratchpad temperature10 temperature12 temphigh tempres

So, you can add 28.BF16270A0000 = type,temperature And it will open type and temperature file for sending /1wire/28.bf16270a0000 {"type": "DS18B20", "temperature": "8.125"}

Or even you can use this gateway for sending not only owfs data to MQTT.

To run at boot, make the script executable: chmod +x /your_folder/1wire2mqtt.py and add this to your rc.local: /your_folder/1wire2mqtt.py /your_folder/1wire2mqtt.cfg &
