ampel-api-server
Simlistic/minimalistic API server for my Cleware (Nagios) Ampel
Install
Clone the repo, install a virtual env if you want/need.
Install Flask - via pip:
$ pip install -r requirements.txt
or on your Raspbian via apt-get:
# apt-get install python3-flask
And make sure you have the clewarecontrol [1] tool in ~/clewarecontrol/clewarecontrol.
And run the API server:
$ ./api_server.py
The server has no security or so and is going to listen on 0:8080.
You can therefore access it for example:
$ curl -XPOST -H "Content-type: application/json" \
-d '{ "green": 0, "red": 1, "yellow": 1 }' \
<replace-with-your-ip>:8080/set
The above line will set red/yellow to on and green to off. If you do not specify one color, the current state will not be changed.
To query the states:
$ curl -XGET <replace-with-your-ip>:8080/red
$ curl -XGET <replace-with-your-ip>:8080/yellow
$ curl -XGET <replace-with-your-ip>:8080/green
Further work.
I'd be very interested if someone has an idea how to query the different colors using pure Python USB - at the moment this tool uses the clewarecontrol [1] tool to query tht states, since the cleware-traffic-light [2] Python module doesn't do that and I'm not too familiar with USB programming.
