Wie: FHEM per HTTP-GET steuern mit Arduino

[EnderPhilipp]

Hi Liebe FHEM-Community,

ich habe mir folgenden Sketch zusammengebastelt.
Dieser wertet ein paar Sensoren aus und soll diese per HTTP-GET an FHEM senden.
Die Sensoren lassen sich auch auswerten, nur das senden der Variabel an FHEM klappt nicht.
Ohne Variable (z.B. /fhem?cmd.Stehlampe=setreading%20Stehlampe%20state%20off) funktioniert einwandfrei.

Was mache ich falsch ?

Mfg
Philipp
