thank you very much. it worked like you said. but as I need grouped graphs, I probably will (mis-)use the moisture variable type, so that I enter into the standard variables of mysensors.

thanks again !

Hi all,

small typo in the script: the variable is defined as toAddresses but used later toAddress.

That caused the "400: Bad REquest" Error (at least on my side).

It took me several hours to find this basic error anyway I learned a lot with it.

with regards,

ps.: for all who participated in this software: thank you very much, it's a great tool and running in my home since months without any problems.
