values in json without quotes

[hns666]

The Feature

Hello,
i am trying to integrate the watermeter into ClearScada by Schneider Electric. After 2 days i found out the problem. The values in JSON are with quotes and that represent a string for scada. As there is no option for string point (except sparkplug B) i am not able to get values into the scada. When i tried to do manual publishing of json without quotes i was able to get value.
Is it possible to add at least checkbox that i want to have vlaue in string or number format?
It will be really helpful for me.
Example :
actual json look like that
`{
"main":
{
"value": "868.9640",
"raw": "00868.9640",
"pre": "868.9640",
"error": "no error",
"rate": "0.000060",
"timestamp": "2024-12-18T18:27:05+0100"
}

}`

i need to be like that
{ "main": { "value": 868.9640, "raw": "00868.9640", "pre": 868.9640, "error": "no error", "rate": 0.000060, "timestamp": "2024-12-18T18:27:05+0100" } }

I have no knowledge about mqtt. Maybe all i wrote above is wrong.
I just need that at least "value" is reported as numbers. Not a string. To broker.
As broker i am usin mosquitto from eclipse.
