onion-weather

This is a program for getting weather data from a NetAtmo account and displaying on the OLED display of an Onion Omega device.

Installation

NetAtmo client credentials

This application tries to get data from the NetAtmo API. For that to work you will need to create an application in the NetAtmo developer console, so that you can get a Client ID and secret.

Build/download the binary

If you want to run this on the Onion Omega you will need a Go installation that can compile to MIPS32 (Go 1.8 or newer). If you have that version installed you can just get the code using go get and then use the provided build script to build a binary:

go get -d github.com/xperimental/onion-weather
./build-mips.sh

If you do not have a matching Go installation you can download a pre-built binary from the releases page.

Install on device

Now you need to copy the binary to your Omega, for example using scp.

There is also an init-script and an empty configuration file in the repository. Place the script in /etc/init.d. The script expects the binary in /usr/sbin, either put the binary there or adjust the script.

Put your client credentials and your username and password into the configuration file and place it in /etc/onion-weather.json on the device.

Now you should be able to start the service and see your weather data:

/etc/init.d/onion-weather start
# To stop
/etc/init.d/onion-weather stop

If you want to run the service when the device boots run this command:

/etc/init.d/onion-weather enable
# To disable
/etc/init.d/onion-weather disable

Debug

For debugging you can enable "dummy display" output on the console using the --dummy command-line parameter or using the useDummy configuration option.

Debug output will look something like this:
