Hey @all 
Now i am able to send the Temp and Humidity to TTN and see the payload and the Values but when i test it to send to my ThingSpeak Account then the Values are not correct because the payload must be in a ThingSpeak Format. Maybe anybody know how i format i correct !?
I only want Sensor Nodes with 3 Fields ( Temp / Humidity / BattVoltage ).

* This example sends a valid LoRaWAN packet with payload "Hello,
* world!", using frequency and encryption settings matching those of
* the The Things Network.
*
* This uses OTAA (Over-the-air activation), where where a DevEUI and
* application key is configured, which are used in an over-the-air
* activation procedure where a DevAddr and session keys are
* assigned/generated for use with all further communication.
*
* Note: LoRaWAN per sub-band duty-cycle limitation is enforced (1% in
* g1, 0.1% in g2), but not the TTN fair usage policy (which is probably
* violated by this sketch when left running for longer)!
* To use this sketch, first register your application and device with
* the things network, to set or generate an AppEUI, DevEUI and AppKey.
* Multiple devices can use the same AppEUI, but each device has its own
* DevEUI and AppKey.
*
* Do not forget to define the radio type correctly in config.h.

}
and the payload decoder in TTN is this:
if(bytes.length == 1) {
if(bytes[0] == 1) {
return {
'button': 'activated'
}
} else {
return {
'error': 'button action unknown'
}
}
} else if(bytes.length == 4) {
var humidity = (bytes[0]<<8) | bytes[1];
var temperature = (bytes[2]<<8) | bytes[3];
return {
'humidity': humidity/ 100,
'temperature': temperature/100
}
} else {
return {
'error': 'payload unknown'
}
}
}
and thats the Thing Speak (right) decoder format :
function Decoder(b, port) {
var var1 = b[0];
var var2 = b[1];
var var3 = b[2];
var var4 = b[3];
var var5 = (b[4] << 8) | b[5];
var var6 = (b[6] << 8) | b[7];
var var7 = (b[8] << 8) | b[9];
var var8 = (b[10] << 8) | b[11];
var lat = (b[12] | b[13]<<8 | b[14]<<16 | (b[14] & 0x80 ? 0xFF<<24 : 0)) / 10000;
var lon = (b[15] | b[16]<<8 | b[17]<<16 | (b[17] & 0x80 ? 0xFF<<24 : 0)) / 10000;
var height = b[18];
var myStatus = b[19];
return {
field1: var1,
field2: var2,
field3: var3,
field4: var4,
field5: var5,
field6: var6,
field7: var7,
field8: var8,
latitude: lat,
longitude: lon,
elevation: height
}
}
But i don´t know how to change the payload format in the Arduino code to match the decoder above ?!
thank you all for any help and Info
