@Will_o_Wisp @alwin.k @Bulletcather - I made an attempt adding Tempest support and my quick and initial tests seem to work fine.
I have not yet created a pull request to the @Will_o_Wisp original repo as i plan more testing first. Just got the Tempest today 
But if you or anybody else would like to try, please install it via the CLI and give it a go. Here is the link to the feature/tempest branch of my forked repo:
