ComfoAir connection via USB by ID

General
1

Hi,
i have the node-red-comfoair node installed and i really like it!!!

The only thing is, that whenever there is a restart it could be that the comfoair is using a different USB port and i need to go to the code and change it,....

It would be so cool to implement the connection by usb ID to make sure it's alway working correct.

Maybe someone (@coolchip ) of you has an Idea or maybe can implement that in the node.

Thanx really a lot for this nice implementation!

Kind regards,
Mark

Hi,

If you use a Raspberry Pi, you might look at PersistentUSBDevices - Domoticz
For other OS, you may google for persistent USB.

Hi why not use an MQTT node and assign the COM port dynamically?

If you are using something like a Pi or a Linux based OS then, with the device unplugged, run
ls /dev/serail/by-id
then plug the device in and run it again. If you see a new entry, possibly something like

ls /dev/serial/by-id
usb-FTDI_USB__-__Serial-if00-port0

then you can use that to identify the device, if the node will accept it, so in this case it would be
/dev/serial/by-id/usb-FTDI_USB__-__Serial-if00-port0
