Domoticz

Hello dear user community


Sorry for my English, Google Translator helped

I don't know if I'm right here, but I'll try to explain. I don't get any further due to a lack of skills and little documentation.


I have a Rasbeery pi3 running in the garden with rtl_433 USB STICK and also 2 x 433 mhz temperature sensors, I have the output of the temperature data saved in json via rtl433 on the raspbeery in the garden.

At home I also have a Raspbeery pi 3 with Domoticz to run. with DSL

I update the Json file from the garden with Weewx Update on a third-party server via LTE hotspot.

I want to integrate the Json file into Domoticz ..!


I can read the Json file from the foreign ftp server with the HTTP poller, no problem. ....

I don't know how I can evaluate the json data via HTTP poller and Lua so that domoticz understands the json file.

It's not a static json ....

I've tried a lot of options, but I can't find the right solution.

I also know weewx-sdr, so I have a problem with that and can't get any further.


Maybe someone can help me with this problem via Lua or other options or ideas.





Maybe there is another possibility.

Many Thanks






My saved json file from rtl_433 looks like this.

You might want to look at the examples at the dzVents wiki page how to to process JSON from http calls.

Thanks for the information

yes, I know the site, it doesn't help me any further, because I have no knowledge of programming .... or there is no example for my json data stream ...

Hi Klaus,

please help me, if i correctly understood your problem:
The raspberry in your garden sends his output via an LTE hotspot to an server. And you would like to read this file from the server?
OK -> No problem.

What should be the rythm? Once a minute? All five minutes? Every hour?

What do you mean with "It's not a static json ....". The scheme of the example you've posted is static.
In your example there are more than one entry for each device. Which one should be used? The first? The newest? An average?

Please serve this informations. And i can help you.
Best regards to Berlin
