RFXtrx433XL does not connect

[insomniux]

Hi, I'm having a problem getting my RFXtrx433XL communicate with node-red. Nodered is newly installed on a Pi with the RFXtrx connected to /dev/ttyUSB0. This node remains to report 'Connecting' and never issues a message to debug:

[{"id":"5dafa944.694f28","type":"rfx-sensor","z":"23caef91.7f99a","name":"","port":"aa3c02a8.79614","topicSource":"all","topic":"","x":80,"y":280,"wires":[["523c366b.592968"]]},{"id":"523c366b.592968","type":"debug","z":"23caef91.7f99a","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","x":330,"y":280,"wires":[]},{"id":"aa3c02a8.79614","type":"rfxtrx-port","z":"","port":"/dev/ttyUSB0","enableDebug":true,"rfyVenetianMode":"EU"}]

Here some outputs of my system configuration: lsusb

I guess it's something with the configuration of ser2net but unfortunately the manual of RFXcom is outdated and does not include the newer raspbian versions.

Thanks for your help!

I don't have one of the new XL transceivers here yet...

Please can you enable rfxtrx-port debug, and post the console output from Node-RED. This option is on the 'Serial Port' edit pane:

The messages should look something like this (where I connected the RFX after starting Node-RED):

Thanks for your advise, maxwellhadley. The solution, however came from an unexpected direction. Actually, when I checked, the debug-option was activated. I disconnected and reconnected the RFXtrx and after it came up, it was immediately showing the connection is OK. This remained after a reboot. I've been able to catch information from switches and forward the topic/payload to another MQTT broker. Thanks again for your time, and brilliant work!

OK - thanks!
