So helping a friend with their network and they use hover for their DNS. I did find a python script (https://github.com/tofumatt/dynamic-dns-on-hover/blob/master/update.py) that looks like it will dynamically update DNS with Hover and there does seem to be a few paths to run python on OpnSense. Before I run off and cobble something together thought I would check to see if anyone else has solved this and would care to share. I've done quite a bit of searching and there are some promising threads as far as python goes, but most of those methods look like you need to be careful of upgrades wiping something out, etc.
