Paid Development Request: Driver for Raddy L7 JSON

[Michael]

Hello,

I currently have a Raddy L7 LoRA station.  It appears that that the weather station provides a JSON output of observations.  I am soliciting a paid opportunity to develop a driver for this weather station and create a Github page for driver to spread the word.  I am just a personal user, but figure this may be a better approach than having to buy a supported station.  I am not a developer and simply don't have the time to undertake the effort, but want users of this weather station to be able to use WeeWx (Yes, I tried Interceptor, but I failed in getting to work and this appears to be a more graceful approach).  If you are interested in the work, please let me know.  

 The JSON URL is http://ip/client?command=record

The update period appears to vary between 5-30 seconds.

I have a Raddy WF-100SE station that I would like to get data to aprs.fi and CWOP. If anyone has any suggestions it would help.

[Michael]

I would verify if you can get the observations out of the unit like I was able to.   

I went with CumulusMX instead of WeeWX and their board suggested translating the JSON to a ECOWITT HTTP Post.  Script is in the thread below.  Overall, I am happier with CumulusMX both in terms of product and support community over WeeWX.  I was able to enable the WXNOW file for Direwolf to post APRS reports easily.

Michael,

Thank you for your response. I am not familiar with JSON. The WiFi setup for the WF-100SE says to connect to the L7-xxxx network and using a browser type in 192.168.1.5. That brings up a page where I type in my network SSID and the pass key. Below that is sections for adding IDs and keys for linking to weather unground and weather cloud.

I reason if I can link to those I should be able to link to APRS.fi and CWOP but I am not sure how to do that.

go to http://192.168.1.5/client?command=record  Do you get a result?  

[Eddie Bryant]

Michael,

I get a page that shows the data.

I would head over the CumulusMX forum like.  I posted a Python script you can modify to reformat the data for CMX.

Hi Michael,

I am on the Cumulus support page looking for your script. Trying to find it. 

Eddie 

[Eddie Bryant]

I did a search for Python script but there seems to be a lot of posts. What is your user name there?

Thanks, I have copied the Python script file. What did you call the file and did you set it up to execute automatically on booting Linux? I am thinking of creating an O.S. using CumulusMx Raspberry Pi image.

Michael,

Is JSON something that needs to be installed before running your script? I noticed that it is imported.

I see that JSON is a library included with Python. I installed the CumulusMx image on my Pi4. I was going through the first time setup and was wondering what is the best station to use to be able to send data to APRS and CWOP. I thought about Ecowitt but it wanted information I didn't have.
