Hi there @jjohnston7 great to have you with us and thanks for your interest in Mycroft.
To create a new Skill for Mycroft, you will need to know some basic Python programming Skills - just like for AWS you need a basic understanding of Lambdas.
Why not suggest Homeseer as a Skill on our Skill Suggestion area - that way others can see if they would like to join in to help build in Homeseer support?
