Serial Gateway Issue with Node-Red

[bpair]

I am using a serial gateway connected to node-red. I am trying to parse the serial output but having problems. It appears that the node-red messages may not be "splitting" correctly (or mysensors is not outputting them correctly). At first you see a bunch of what I think are node ID requests. This seems strange to me because I am setting the node and child IDs in my sketch (Using version 1.5 of mysensors). I have two nodes:

• node=50 (arduino UNO)
  -- child=0(DS18B20)
  -- child=20 (DHT22 Humidity)
  -- child=21 (DHT22 Temperature)
• node=30 (sensebender)
  -- child=1 (Temperature)
  -- child=2 (Humidity)
  -- child=130 (Voltage)

Looking at the serial output in node-red

You can see that the last couple ,messages did not appear to split correctly. Is this a problem with something I am doing or node-red or mysensors?

Has anybody had this trouble?

@bpair
I think I found the issue with my serial port configuration:
baud rate: 115200
data bits: 8
parity: none
stop bits: 1
split input: after a timeout of 10ms

I have since changed the "split input" to split on "\n" chracter

@bpair
Yes, split by \n, I also tried the timeout option as a start, but changed to \n..

I've made a couple of plugins for Node-Red, that could be used to parse / generate messages to mysensors serial gw.
