First, thanks for your reply and time you take to guide le in the correct direction.
Now I’m completely lost. 
1st tried to set this Sofar up using the HACS module from Stephan Joubert
And from the issues I found out that I was not the only one not getting data. This does not require an API, correct?
2nd try, is the online API from Skully that I found (and also incorporated your findings)
Got the API info this week so started around noon playing around with the received info.
My JSON info that I get from JSON Path Finder
{
"code": null,
"msg": null,
"success": true,
"requestId": "f15ee17e81fcd340",
"deviceSn": "2104559628",
"deviceId": 213282644,
"deviceType": "COLLECTOR",
"deviceState": 1,
"dataList": [

},

},

},
{

"value": "0",
"unit": "s",
"name": "Offset time"
},
{
"key": "SEND_PERIOD1",
"value": "5",
"unit": "Min",
"name": "Data Uploading Period"
},
{
"key": "COLLECT_PERIOD1",
"value": "60",
"unit": "s",
"name": "Data Acquisition Period"
},
{
"key": "max_conn_n1",
"value": "2",
"unit": null,
"name": "Max. No. of Connected Devices"
},
{
"key": "SGits1",
"value": "0",
"unit": null,
"name": "Signal Strength"
},
{
"key": "HEA_F1",
"value": "120",
"unit": "s",
"name": "Heart Rate"
}
]
}
I get the idea that I don’t get all info from Solarman.
Setup is a Sofar with Battery and sensors to verify power from provider and solar panels (separate installation).
