JSON output and single query?

[ctschach]

Thanks for the brilliant work on this project. Pretty amazing what you have created so far.

I totally understand your approach of getting data in the MQTT. However, I would love to use it for single queries. So instead of running a delay and then query the device again, I would like to just quit the script. In addition I would love you you could do a JSON encoded output to stdout.

I'm not that familiar with Python, so not sure if I would be able to change the code accordingly (and pretty).

But is this anything which we could add to the project? Or would this be against the overall concept?

Thanks! I already thought about something like that and started some time ago to introduce the "direct disconnect method". I can improve it to quit after getting the data once. At least for serial and bluetooth-ble connection method. The bluetooth connection method get its data via async functions and not always all data, but I could add an config parameter to define for which data should be waited.

The output via JSON shouldn't be to complicated.

Hopefully I find the time next weekend for some programming...

Sorry for the delay. I have added json as output option in configfile. For serial and bluetooth-ble there is a --direct-disconnect option to run only once. I will try to add a similar option for bluetooth connection method soon. You may want to add an collection to your configfile and run the program with -c, otherwise it will print the first single value as a single json output and then exit if you use --direct-disconnect. With a collection you can "merge" it into one output with all values.

If it is not clear from my comments in the configfile, I can provide you with a sample config, if you tell me which device and connection method you are using,

Is the output what you expected?
