I’m presuming the 2 different Flows counts are Standard Flows and Advanced Flows?
And I’m also guessing the Flow Checker app counts variables in quite a different manner 
(I’m guessing the number of times any and all variables being used occur in all Flows, as opposed to a count of actual unique variables.)
As it appears the API provides some other system details, at least that apps can access… would it be possible to add things like current CPU temp, load average, and any other useful system health stats. My thought is to run the script from a Flow and save the results to a string variable, which I can then use the Email Sender app to email to one of my inboxes I use for network, server, and system health messages. That way I have easy access on my mobile to plain text messages providing daily status updates for all my home network.
Thank you kindly for you consideration and time.
