How to manage WIFI settings via dashboard

[KirchnerAlex]

So, i switched back to an "nativ" installation of node-red without snap.
In this case i can use NMCLI directly from Node-RED

I want to learn more about snapd, but at the moment i have not the time

I switched to snap because i had problems with connecting to ttyUSB0, But for that i also have found a solution. See this post:

Node-red-node-serialport 0.6.8 not working (0.4.2 do)

Sorry about that generally topic, but i do not really know how to ask. I have a heatpump system with an USB-Interface which sends and receives simple Strings like "13 1234" Want ro read/write this strings. With my Device A it works Device B not works (no data in or out), but i have no idea why. When i Install the older version of the node-red-node-serialport node it works fine. But what can i try, that i can use newer version? THANK YOU Device A: Hardware NanoPi NEO2 Ubuntu core 16.04 L…
