Honeywell's line of smart thermostats is used in residential and commercial settings in countries worldwide.  As one of the top choices for residential building solutions, there are several Honeywell smart thermostat models to choose from - all of which can be controlled and managed via Honeywell API.  This article will detail some of the most meaningful features of the Honeywell Smart Thermostat that are exposed by the Honeywell API.

5 Things You Should Know About the Honeywell API

  1. Honeywell API allows you to control thermostat mode and temperature from a custom app experience

    Honeywell provides a fantastic app for homeowners to use to control their thermostats, whether at home or away.  But if you're managing properties, expecting tenants and guests to download an app and create an account for every smart home device to which they'll have access is a tall order.  The Honeywell API allows property managers to build a single app experience into which thermostat mode and temperature control can live alongside other important features such as wifi information, local destinations, bill payment, or other features.  This convenience adds a ton of value for guests and tenants.    

  2. See and be notified of thermostat changes as they happen

    The Honeywell API allows your app to be built so tenants can see thermostat changes as they happen.  This can be convenient in cases where multiple tenants/guests control a thermostat.  If one tenant makes a change to the thermostat either directly at the unit or through the app, the other tenants can see that change immediately.  This is also convenient when you want to notify an owner or others in real-time when a space has reached a target/goal temperature. 

  3. Reduce your energy bill with proactive climate management

    Honeywell thermostats support smart, sophisticated features for automatically managing climate based on their ability to sense when a unit is occupied, season of year, and owner control habits.  It can also support a schedule for climate management if you don't want to rely on smart features.  But what if you are managing a vacation rental property?  Guests have wildly different preferences - and schedules - that they want for managing their space.  The Honeywell API allows you to extend control to tenants through the custom app support features, but it can also be used to turn off/on an HVAC system when guests check out, ensuring the unit is not heating/cooling a space that's not being used.  You can use inputs from other systems such as smart locks or property management systems to automate turning off a Honeywell thermostat when a guest has checked out.  This approach takes advantage of multiple systems to ensure a unit isn't wasting energy to heat/cool an unoccupied unit. 

  4. Improve guest experience by cooling or heating your property for arrival

    If you're managing a vacation rental property or showing a vacant rental unit, the first impression has a major impact on the tenant/guest experience.  With the Honeywell API, you can automatically pre-cool or pre-heat a space based on inputs from a scheduling or property management system.  You can also stop heating/cooling a space after the visit.  This approach ensures the first impression isn't hindered by climate challenges in the space.

  5. Manage multiple thermostats from a single screen

    The Honeywell API allows you to create user experiences for managing thermostats, not limited to tenant experience.  If you're managing multiple properties, you can use the API to build management dashboards that allow you to visualize, manage and control thermostat temperature across all of them from a single screen.
