Hello I am running home assistant on a container on jetson nano.

I am trying to run a serial node as I have a device that is using simple serial commandes I am trying to use node-red-node-serialport 1.0.1 ([node-red-node-serialport](https://flows.nodered.org/node/node-red-node-serialport))

When I try to run the node red I get a error log like this

How do I solve it? I did try to follow this Topic [https://discourse.nodered.org/t/using-gpio-via-node-red-on-the-jetson-nano/16629/3](https://discourse.nodered.org/t/using-gpio-via-node-red-on-the-jetson-nano/16629/3) but I can't find where the file is located.

Is there any other nodes that can allow simple serial port read writes? I tried this node [https://flows.nodered.org/node/node-red-contrib-serialport-rs485](https://flows.nodered.org/node/node-red-contrib-serialport-rs485) but I couldn't install due to compatibility issues

Hi there, the log you've shown does not have an error really. It is only telling you that the Raspberry Pi specific node doesn't work on anything other than a Pi.

Have you tried installing node-red-node-serialport from the pallet manager? Note that it will almost certainly require a build step and so you will need to have dev-tools installed.

Thanks for your quick reply when I installed the node red it already installed node-red-node-serialport for me.

What I mean is when I deploy a serial node with this settings

my node red stops working with the log as my first post

OK, so firstly try removing the `node-red-node-pi-gpio` node to make sure that isn't causing problems. Also make sure that the user id that is running node-red has access to the serial ports. On most versions of Linux, I think if you add the user to the `dialout` group, that should work but do double check.

Also, since you are running node-red in a docker container, you might have to do some jiggery-pokery to permit the container to use the physical serial port (not sure if HA already sets this up - you will have to ask on the HA forums)

Here is how someone using docker would setup a container to access the physical serial port...

If that all seems too much, then ditch the HA Node-RED Addon version red and install node-red to the OS instead.

I missed that. I'll update the tags to make it clearer.

Thanks I tried disableing the `node-red-node-pi-gpio` and now the program is stuck in this loop

Well, as you can see, Node-RED is not reporting any errors. I would increase the logging level in settings.js to see if you can spot what is causing the restart.

If that doesn't show anything then I'm afraid that I think it is either a Docker or more likely, a home-assistant issue and you may need to ask on the HA forum unless someone else here knows. Personally I use neither HA nor Docker for Node-RED.
