Last seen?

Hello,

I have a problem with a sensor that is not updating in the dashboard. In the hardware setup page for mysensors gateway v2.0 I see "last seen" update every 10 sec. But under device I can see the device but it doesn't update more then once. "Last seen" in device page doesn't update. So the temperature doesn't update in the dashboard. What am I doing wrong? I'm kind of new at this.

The sketch looks like this:

@kk02067 please enclose the sketch in a "code block" to allow easy reading... you can also put 3 tick marks (back quote ` ) on both sides of the code
0_1468736519864_upload-98eef9b5-32b9-4f23-a150-d75f0529bf58

What does you debug on the serial output of the node tell you? (also enclose in code block ;-))

@AWI

Thanks for your reply and tips to a beginner.

I experimented with a couple of things in the sketch and after a little digging I seem to have got it working.

The problem seem to be that if the values sent to the gateway is not in the correct format it wont work. If I send just one value in integer it works. But if I send alla three values as integer it stops working. If I send all three as "double" with two decimals it works as it should.

The sketch when it functions as it should:
