Smart thermostats: I have temperature sensors (or smart thermostats) installed in each unit because I want to make sure the tenants don't turn off the heat in winter. 

.- Keep HVAC running at a minimum of 55F- Open vanity doors and cabinets where pipes are running.At this moment don't do anything until temperatures are over 32F for good amount of time.

My property is in upstate NY where we are expecting temperatures between -4 and 20 degrees F for at least the next 10 days.

Many lock companies claim Operating Temperature: -20°F, don't fall for it.

As a guest, I can imagine being frustrated if I could not get a home to a temperature that felt comfortable to me.

I have a BTR (Build to Rent) buyer I might pitch it to, but wanted to check the temperature on the area first.

One thing I'd add - track response time by lead temperature too.

I have had issues with the batteries going out too frequently so may explore other options but I do have older models which may be less efficientNoise Monitors: NoiseAwareAlerts me by text when noise levels are above a certain threshold for a certain timeframe so I can contact my guests and stop any neighbor noise complaints before they happen (I’ve only had noise issues 2-3 times in my entire hosting journey)Smart Thermostat: EcobeeSyncs with Hospitable to change the temperature to my presets when a guest checks out and before a new guest checks in.

Chicago's heat ordinance requires a minimum daytime temperature of 68F, nighttime 66F, and may God have mercy on your soul should that not be met.That means you are installing electric baseboard heat as a down and dirty solution (eliminates need for third gas meter, too, as stove can be electric).

Their customer service team is awesome too if you get stuck.If you are using the Schlage Encode smart locks or any other compatible lock and thermostats, you can connect these to Hospitable as well so it will generate unique codes for each of your guests automatically and adjust the temperature when guests are not there!
