Daikin ONE+ Smart Thermostat: The Brain of a Communicating Daikin System

Direct Answer

The Daikin ONE+ is Daikin's flagship smart thermostat — the first with full two-way communication with Daikin HVAC systems. It controls temperature, humidity, and (with the Daikin One Home Air Monitor) indoor air quality, works from a touchscreen, dial, phone app, or voice assistant, and is the required thermostat in a full Daikin FIT rebate system.

Why 'communicating' matters more than 'smart'

Plenty of thermostats are Wi-Fi 'smart'. The Daikin ONE+ is different because it speaks Daikin's own two-way protocol: it doesn't just switch the system on and off, it exchanges real-time data with the equipment. On a variable-speed system like the Daikin FIT, that's what lets the equipment modulate precisely — including running dedicated dehumidification behavior instead of guessing.

It's also why the ONE+ can show error and service notifications generated by the system itself, which means we can often diagnose an issue from the fault history instead of hunting blind.

What you actually get day to day

The unit has a high-resolution color touchscreen plus an anodized aluminum dial for quick setpoint changes. The SkyportHome app gives you full control from anywhere, and Amazon Alexa and Google Assistant handle voice commands. A programmable 6-event schedule, Away mode, and geofencing quietly cut runtime when nobody's home — which in a Florida cooling season is real money.

Pair it with the optional Daikin One Home Air Monitor and the thermostat displays your indoor air quality alongside outdoor conditions — useful in humid Gulf Coast homes where moisture and air quality problems tend to travel together.

The rebate connection

Daikin's current instant-rebate definition of a 'full FIT system' is the FIT outdoor unit, a matching Daikin furnace or air handler, and a Daikin ONE smart thermostat. In other words: the thermostat isn't an upsell accessory — it's part of what qualifies the system for the $750 instant rebate through July 31, 2026.

Frequently Asked Questions

Does the Daikin ONE+ work with non-Daikin systems?

The ONE+ is designed around two-way communication with compatible Daikin equipment — that's where its humidity control, precise modulation, and system diagnostics come from. Daikin publishes compatibility for specific unitary, S21, and VRV systems. If you have a different brand, we'll recommend a control that actually fits your equipment rather than forcing a mismatch.

Can it control humidity, not just temperature?

Yes — Daikin describes the ONE+ as an integrated controller for temperature, humidity, and air quality. On communicating variable-speed systems it can drive dehumidification behavior directly, and with the Daikin One Home Air Monitor it visualizes indoor air quality on the thermostat and in the app.

Is the Daikin ONE+ included when you install a Daikin FIT?

If you want the current $750 full-FIT-system instant rebate, yes — Daikin's program defines the qualifying system as the FIT outdoor unit plus a matching Daikin furnace or air handler plus a Daikin ONE smart thermostat. We'll show the qualifying configuration and the rebate line on your written estimate.
