Using a pi zero for sensors while my main host is a laptop

I've successfully been running Klipper for a few years off an old laptop, but it's running out of USB ports. I also have a pi zero w and some ESP32/8266s and sensors left over from other projects. I'd like to use one of those boards as a chamber temp sensor for my enclosure so it's natively part of Klipper rather than only visible in HomeAssistant like it is currently.

Looking at the klipper docs I see instructions for accessing the GPIO pins when you're using a pi as the klipper host, and I see instructions for using a secondary mcu like toolhead boards, but not for using a pi as its own secondary MCU.

Am I overthinking this? Can I just flash the pi via kiauh? Is there a reason this isn't possible?
