My place is out of state and I have a cleaning person and a property manager handle the day to day stuff that I can't.
I have been having issues with the electronic lock burning up some batteries so I guest have told me that they had an issue getting in the back door. Those that don't I don't know that they have arrived and got in OK.
But, I also have Spectrum cable that has an app that lets me know when a new device is connected. The lock isn't presently time delayed but I laugh how *quickly* some guests are logging into the WiFi. I assume it's the kids...hey kids, look at your device while we unpack the car, but it kind of makes me laugh. At least I know they got in OK.
I'm going to replace the locks when I'm vacationing in my own space with the kind that's connected to the internet. Then I can set codes for each guest and it'll let me know when they get in and I can breathe easier.
