Buderus KM200 api

I don't think it is related to the line 101. REST sends a json results, that is supposed to be enclosed in {}.
In your case, I would say the problem is probably with the first "{", that seems to be missing.

That was a copy paste error from my side. Real JSON answer is:

Code:

{"id":"/solarCircuits/sc1/collectorTemperature","type":"floatValue","writeable":0,"recordable":1,"value":-0.6,"unitOfMeasure":"C","state":[{"open":-3276.8},{"short":3276.7}]}

By the way, as in the code you are searching for } it doesn't have anything to do with the {. 

Let me rephrase the issue.
The output that I got after the code:

Code:

local endposition = string.find(res, "}", -0)
res = string.sub(res, 0, endposition)
return res

is

Code:

{"id":"/solarCircuits/sc1/collectorTemperature","type":"floatValue","writeable":0,"recordable":1,"value":-0.6,"unitOfMeasure":"C","state":[{"open":-3276.8}

This is not a valid JSON response as the last } (and some more text) is missing. I assume the -0 in the string.find is not the correct value.

Anyway, thanks a lot for the code It works like a charm so I'm happy with it!
