Homeduino with Arduino on NUC?
Let me ask you a, perhaps somewhat stupid, question.
Can I connect the Homduino plugin with Arduino to an Intel NUC?
This would allow me to equip the NUC with GPIOs and completely disconnect the RasPi. Actually, nothing against it, right?
Or would something have to pay special attention?
Currently I use an Arduino Nano for Homeduino with a RasPi. Could I also use another Arduino with more GPIOs for Homeduino (with NUC)?

This SHOULD work assuming you connect the Arduino via USB to the host computer (Raspi or NuC). I am writing SHOULD as I only tested this myself using a DEV-Setup (no npm install, essentially) on Win10. You can use Arduino GPIO with Homeduino, but supported is currently limited to digital out (Switch) and PWM out (Dimmer) - see https://github.com/pimatic/pimatic-homeduino#local-actor

Hello and thanks for the info.
I have tried it. I am using an Intel NUC 8i5. On it is running Proxmox with a few VMs and containers.
I have Pimatic installed in a Debian VM. NodeVersion 10.23.3 and npmVersion 2.15.12.
The system runs excellent fast. A reboot takes only seconds. Although pimatic has only 2 cores and 2GB Ram available. When I want to call the statisk of a device, it often takes minutes on the Raspberry, or the process aborts at some point. With pimatic on the NUC, calling up the statistics also works in seconds.
I have passed the USB port to Debian with pimatic. Then I connected an Arduino Nano and installed the Homedino plugin. Currently I have only created one Homeduinoswitch device. It works. So it is possible to implement GPIOs even on devices like the NUC.

@thrusty Sound great.
Out of curiosity I have checked whether or not NuC provides for GPIO headers in general, and actually some models do!
If you have an applicable model suitable kernel drivers appear to be available for Linux and Windows. On Linux the gpio channels are logically mapped to io devices. There is a tech note which describes all the details including examples how the io states can changed using file system commands. However, this should be used with care as the electrical characteristic of the extension header may no be as robust as what it is with raspberry pi.
Here is a tech note for some older models. There may be more information on the Intel website for other models
