There is a smart thermostat in the house I am renting. 

You should upgrade your properties to be monitored remotely with software, apps, wifi, thermostats, locks and cameras. 

Each room has its own thermostat. 

Now if you have a C wire coming from the furnace to the thermostat or if you decide to run one you can use any smart thermostat.

-There is previous water leak spotted in chimney siding -Low water flow rate even though water pressure checks good - hot water heater is working but old - windows probably need replacement some don’t stay open and one window can not open at all -new smoke detector needed -ac thermostats works but is miss wired -few small electrical works I am gonna call my agent and discuss possible price reduction or have them fix some of these issues.

Just monitoring the thermostat, temp and the main door right now.

Mine can set door codes, message (or call) guests, schedule cleaners, adjust the thermostat, monitor my cameras, & call a plumber just as easily as a local PM can, for 1% of the costI wrote much more about leveraging offshore assistants in this post here.

I read a news article that the Vegas utility providers encourage customers to sign up for "smart" thermostats that allow the utility provider to adjust your home's temperature.

I would set up a zone in that area with a 45 degree thermostat.

The premise of the book is to "re-set" your internal blueprint (or thermostat as he calls it) to understand why you are where you are, and what you can do to adjust it.
