Extension weewx-json: want to get data for several inside temp/humidity sensors

[Herbert Schoenhammer]

I'm a new user of weewx. I've installed weewx

WeeWX-Version 4.10.2 on a rapsberry pi

and i'm using the standard Skin

Skin Seasons 4.10.2.

I've connected  dnt Waether Screen Pro using ecowitt Protocol (using https://github.com/matthewwall/weewx-interceptor). 

To dnt Weatherstation I've connected several sensors for measuring inside temperature/humidity for several rooms inside the house.

In the skin Season4.10.2 everything works fine. In current conditions alle sensors are listed. Example:

Raumtemperatur
21.7°C
Raumluftfeuchte
62%
Temperatur1
21.6°C
Feuchtigkeit1
73%

But using the weewx-json extension (https://github.com/teeks99/weewx-json), I only get the Temperatur1. I don't get the Feuchtigkeit1!

My Question: How may I get temperature/humidity of all sensors in the json of weewx-json?

Thank you for every hint.

(Or any other hint how to get the current conditions for outside and all inside sensors into node-red!)
