I’m working on designing a system that saves money on heating and cooling costs at hotels by automatically adjusting the thermostat after a hotel guest checks out of a room.

  • Each room has a Sensibo “smart” thermostat that controls the heating and AC unit, and is accessible online through an API

  • The property management system (PMS) has an API available that allows the querying of which rooms have recently been vacated, with the hotel guest having checked out.

A Python script runs using Google Cloud’s Cloud Functions to tie the two systems together, triggered by the guest checkout, and notifying the thermostat API to immediately stop heating or cooling the vacant room.

The system runs automatically around the clock, saving the hotel a ton of money on heating and cooling bills.
