Hello,

I get this error nearly every night and sometimes even up to five times.

2 Jan 02:00:23 - [red] Uncaught Exception: 2 Jan 02:00:23 - TypeError: Cannot read property 'payload' of undefined at Luxtronik._processData (/home/pi/.node-red/node_modules/luxtronik2/luxtronik.js:332:74) at processTicksAndRejections (internal/process/task_queues.js:77:11) nodered.service: Main process exited, code=exited, status=1/FAILURE pam_unix(sudo:session): session closed for user root nodered.service: Failed with result 'exit-code'.

NodeRed v2.0.6 node -v v14.18.1 node-red-contrib-luxtronik2 v0.5.1

Should be fixed with https://github.com/coolchip/luxtronik2/issues/28. Try new version. v0.5.2

Thank a lot. I just updated and will test it.

Sorry for bothering you again but the error just changed.

Oh... you're right. I've done it the wrong way. Try node-red-contrib-luxtronik2 v0.5.3

But keep in mind: The problem is not the node. Your luxtronik stops sending requested data back to node-red. Perhaps there is something with your network or your electricity provider shuts down your heatpump. With my bugfix now you should get an Error output from your node instead of an uncaught exception.

Thank's. I'll test it next few day's.

It's strange I also used an ping node and only ask the heat pump when it is available and still I got uncaught exceptions. My electricity provider has no connection to my heat pump.
