Excellent work!

I just like to mention one thing to keep in mind when testing / developing:

- When I've created the [new Firmata-Node](https://discourse.nodered.org/t/announce-node-red-node-arduino-firmata-remastered-v1-3-4-20250331/96317/9) (called "Arduino node" = bad naming)
- Everything worked perfectly fine and stable with RPi PICO boards connected via USB port to the RPi4: "on a desk".
- But after connecting some real 240V engines to the relay board  
(which is theoretically optic-relay protected)
- Probably the sparks of the relays have created strange EMP effects, which causing many times a complete stop of the communication.  
_(The only solution is to unplug the board from USB and replug ☹ )_

So it is advisable to test it that way too.
