Thank this helps me a lot.
You have mentioned that your weather station sends not the “elev” key.
How do you request the data/key from your weather station?
Can I just type in the browser e.g.
http://my_weather_station_ip/getData
I would like to check what my weather stations sends out, maybe the name is not matching.
But I do not know how to read out these information from the weather station
No, you can’t. Please read the thread from the beginning (I know, annoying, if there’s info splattered across).
You have to configure the weather station in the “WS View”-App to call a certain script. It will then do that periodically - you set the seconds in the “upload interval”.
you can
easiest would be 1. I guess, if you know, where it is.
Also, this is, what my WS3500 aka WIFI50DD sends (Firmware: EasyWeathev1.6.4) - already converted to JSON-format

Thanks, for your tip.
I have added this to the php file:
My first php code but it works 
// write data from weather station into txt file
$result = array($_GET);
file_put_contents("weatherstation_data.txt",print_r($result, true));
Here my data:

)
Here my info regarding the weatherstation Sainlogic WS3500 built 05.2022.
When I look into WSView Plus app the weather station is called "EasyWeatherPro-0FDC2.1
We both have no “elev” and my “dateutc” is only a string with now.
I have created my additional data and changed the the Data to String, makes no sense but I get now all data provided by the weather station;-)
Number Weatherstation_lowbatt "Batterie" <temperature> (gWeather, Wetter)
Number:Length Weatherstation_yearlyrain "Niederschlag/Jahr [%.1f mm]" <rain> (gWeatherHeight, Wetter)
**String** Weatherstation_dateutc "Uhrzeit" <temperature> (gWeather, Wetter)
I think, your Firmware has an bug with “now” instead of a UTC-timestamp!
other than that, it looks good! And beware of your skills in scripting growing over time using openHAB! 
Hi all, for anyone looking to use the ECOWITT output type. Here is a php that performs well. It’s just a modification of @binderth’s amazing code.
You’ll need to use this if you need data such as additional sensors and battery data, which aren’t supported by the wunderground format.
I’ve also included a corresponding items file. I have one additional sensor on CH2. You can add extras as you have configured.
I’ve also included a handy function at the top, comment this back in to troubleshoot and see the values your php file is receiving.
<?php
// Code to log your Ecowitt output to a file for exploration and troubleshooting.
// You'll need to create the directory /var/log/weather/ and give it permissions.
// $date = date_create();
// $handle = fopen("/var/log/weather/" . date_timestamp_get($date), "w");
// $result = print_r($_POST, true);
// print_r(error_get_last());
// fwrite($handle, $result);
// fclose($handle);
// Beispiel von Wetteratation

how do I run the php script can this run on a pi thanks and does it work find in openhab 4
the script has to run on a webserver. could be a small nginx on your pi or if you have, some NAS, which also offer webserver capability. unfortunately, the firmware of the WH3500s doesn’t send JSON, but GET-values, which are not compatible with the REST API of openHAB. You could also upload your data to a cloud service (configuration via APP) and poll it from there
