Is this even possible to load up node and have it running the API stuff like alarm clock and web interface etc?
NodeJS and NodeRed (not sure which one you wanted) is available for all CPU archs. Should install fine on ARMv6.
You can install NodeJS with:
dietpi-software install 9
As for the alarm clock and other stuff you wanted to run ontop of it, i’am the wrong person to ask, no idea
Besides nodejs you also need npm (may or may not be included in nodejs) and git. If these prerequisites are met then the alarm clock should work fine.
npm comes with our NodeJS installer. Should be good to go
git, Either of the following:
dietpi-software install 17 apt-get install git
