Hey Jon if you have interest in having your See Levels interface with your Spyder systems give Spyder a call and they can provide an update. They sent me a file for free that made for a quick update however somebody stated they charged a fee for the upgrade so uncertain if they would charge you or not.
We have a Seel Level monitor in the bathroom, wetbay and of course interfaced with the Spyder so visible there as well as our Eclipse module or the See Level app.
I had a post on parts of that process here: Tank level accuracy with See Level II
