Thanks! Just ordered 1 to play with, I will order 4 more if we can get openhab support.
NOTE: This is a pre-order version of the AutoPi 4G/LTE Edition. The pre-order discount is 10%. Estimated shipping is May 2018.
May is still far away. Even though I’m very interested, I’m going to wait and see.
I just ordered mine. Should be shipping this month. They are still offering the 10% discount.
Got my 3 units today and get them setup, now I just need to tie them to openhab!
Hello,
I discovered AutoPi.io with this discussion. It seems great.
What is your experience with the dongle and software ?
Boot time is better ?
Regards, stephan

Hi,
I came across this thread in a desperate search for an answer on how to connect Traccar to Openhab.
Unfortunately a direct connection of Traccar to openhab does not work (for unknown reasons) therefore I wrote a small python script which converts the Traccar event/position POST messages to MQTT messages:
The python script only includes basic location messages. I will add more as I go (waiting for my car tracker)
server.py
#!/usr/bin/env python3

Edit: to make this script run as a service I had to add delays between the client.publish functions …
traccar configuration (goes in traccar.xml)
<entry key='event.forward.enable'>true</entry>
<entry key='event.forward.url'>http://127.0.0.1:8099</entry>
<entry key='forward.enable'>true</entry>
<entry key='forward.url'>http://127.0.0.1:8099</entry>
<entry key='forward.json'>true</entry>
please note that I run the python script on the same server as traccar.
Everything runs on a Raspi Zero.
I am not really good at programming … any improvements to the script are very welcome
