Do programmers create a script to scrub the data, but then where do they get the data?

@Guevara MikeNothing wrong with being nice given this is your first rental and close proximity to you.You could offer to put in a wifi thermostat if she signs a new one year lease.

HiI am thinking to enroll to Phd programme for real estate, can you advise me with a good topic for thesis, i would like to enrich my knowledge about real estateN.B.

It’s only been a week and the thermostat has been reading near and over 90 degrees.

@Paul Wakim, thank you for the detailed explanation of what you managed to do with your own culled lists using a programmer's services.

If you're the only one charging for gas on top of the rent, then I wouldn't consider it.Unlike water, and if you control the thermostat as I do at my rentals, unless the tenants purposely leave the windows open on cold days to spite you, you do have some control over gas usage.

He could also need access to your wifi for smart home features like keypad door locks, thermostats, lighting, etc.  

You'd need to set the thermostat for the central heat in a common area so that the baseboard heat doesn't effect it, but otherwise I don't see why you couldn't use the baseboard heat to bring each unit up a few degrees to the tenant's liking.

I am getting ready to rent my duplex in an owner/occupy situation, and I'd like to put in a smart thermostat for my rental unit. 

Summer in Scottsdale is really hot (110), you need to lock the thermostat so the tenant can't run the AC at 65 degrees for 5 days straight and kill you AC unit (that was guest #1.. $1500 lesson after the water in the ceiling damage)2.
