Openhab issue: Error during the execution of rule 'Arduino sends to Openhab': 5

Daniel Lindberg

So I've managed to build my gateway and connect it to my RPI running Openhab 1.7.1. I'm now trying to connect my pulse power sensor to the gateway (http://www.mysensors.org/build/pulse_power). I've been following this guide http://forum.mysensors.org/topic/1194/tutorial-openhab-with-serial-gateway, but I'm receiving a very non-specifc error from Openhab. The error message is simply "5". I've enabled debug-logging, but it's now much help.

What can I do to get more info about this error?

I have not checked your code. But opening "{" and closing "}" brackets should have the same count.

I've lately had a similar problem, where the error log didn't help and changed my rules a little.

Could you test the modifications?

I found late last night that the issue was the line

var String msg = message.get(5)

so by looking at your code I'm pretty confident that it will work.

I haven't digged into the details, but it seems like the Pulse Meter request for last pulse count

// Fetch last known pulse count value from gw
gw.request(CHILD_ID, V_VAR1);

doesn't carry any payload, so String[] message has a length of 5 rather than 6. So the error message "5" is some weird presentation of an IndexOutOfBoundsException
