I have had some success after playing with the mydevices.com system. You can connect custom devices using the Python Cayenne MQTT client so I wrote a basic python script which connects to mydevices.com using the MQTT client and uploads the temperature for any connected 1-Wire devices every 10 seconds.
You can find the script at https://github.com/abelectronicsuk/testscripts/blob/master/cayenne_1wire_temperature.py
To get the script working you will first need to install the Cayenne system on your Raspberry Pi if you haven't done so already. You can do this on the Catenne dashboard by clicking "Add new...", select Raspberry Pi and follow the instructions.
Next install the python MQTT library with the command below on your Raspberry Pi.
pip install cayenne-mqtt
To add the 1-Wire sensors click the "Add new..." button, select "Devices & Widgets" and then "Bring Your Own Thing". A page will load with a list of SDKs on the left and the device details on the right. You will need to copy the MQTT username, password and client ID into the python script I wrote, replacing the "USERNAME", "PASSWORD", and "CLIENT_ID" strings on lines 8, 9 and 10. Now run the python script with:
If the script works correctly you should get a list of the available 1-Wire devices appear on the screen and then it will start uploading the temperatures from each sensor every 10 seconds.
Hopefully this will help you get your sensors onto the Cayenne system.
