Any way to connect to phone app to control thermostat for pool?

What would you charge to diagnose dead batteries in a thermostat.....$75 trip charge?...

I agree with John, as long as you have someone to call for any issue that may arise, then you are good to go.Make sure you have smart devices like locks and thermostats that you can control from your phone.The most important person you will need is a reliable cleaner!! 

Smart thermostat or programmable is always a good idea for energy savings (more important if you are including utilities).

All this to say, I want to shout out (sorry for those I am not connected with, the tag doesn't allow me):@John Underwood  @michael baum @luke carl @julie mccoy@paul sandhu (for horror stories and comedy)From which thermostat/locks/water heaters, pots/pans, processes, marketing, all of it... you guys (and gals) have been so helpful.

In a couple of my rentals I have installed Ecobee smart thermostats, and connected them to the tenant's WiFi network.

So, basically when your tenants don't have heat, unless the issue is that they turned off the thermostat, the home warranty is useless.Good luck.

The HVAC unit is working no more or less by conditioning that space, so long as it's a) not pulling return air from the common space, b) is not reading a thermostat temperature from the common space, and c) not dumping an incredible amount of air into the space (all of which should not be happening regardless).

I am installing WiFi controllers for both thermostats so I can monitor and also purchase a cheap wall unit for their bedroom.

. - i.e. digital door locks, wifi controlled thermostats, ring camera on the exterior entrance.
