What does nvalue and svalue represent?

In the JSON-API sometimes the nvalue is used (Air quality) and most times the svalue is used (Temperature, etc.).

nValue = numeric ( one value -- INTEGER DEFAULT 0)
sValue = string ( multiple values -- VARCHAR(200) DEFAULT null )

Yes. But in a lot of examples, there are numbers throwing to Domoticz with sValue. This is little bit confusing. But anyway, if one send number to Domoticz in sValue, it seems working (graphs, averages etc are calculated OK...)

You can find out when to use svalue or nvalue according to the device type in this page:

nValue (Numeric Value) is only integer and is used command option for existing devices:
ON(1)
OFF(0)
STOP(17)
DIM LEVEL(2)
(I think there are more, but up to know I know these)
any other value should be set to sValue (String Value)
