Hi @Todd_Danner,
There is a forum post here with a similar question, I would recommend checking it out!

Should you choose to use the Losant API Node, you would need minimal configuration to return a full list of devices that also includes connection information:
Then, using a Loop Node, you could count each disconnected device and return the total at the end of the loop:
Please let me know if I can assist further!
Thanks,
Julia
