@BrandonT - apparently Rule Manager (RM) works on events, not conditions (Rule for when ALL phones leave, not any phones leave - #4 by bravenel). You had mentioned being on vacation for >1 day. Perhaps RM didn't detect a "leave" event? Enable logging on everything.
Also, how are you connecting to your hub from remote? The Hubitat Remote Admin, or your own VPN? If the latter, do you have any presence sensors that are based on IP? Because if you use your own remote access VPN, your phone essentially is on the same LAN as the hub and perhaps something thinks you're home when you connect to it?
