The short version: WarmlyYours is a radiant floor heating specialist, and the nSpire Touch and SmartStat are its Wi-Fi programmable thermostats built specifically for electric in-floor heating systems. Owner feedback from Home Depot and WarmlyYours’ own review pages is mixed: people find it easier to program than older models and praise the company’s customer service, but a meaningful number of reviewers report plastic components feeling cheap or breaking during installation. It’s a reasonable pick if you’re already installing WarmlyYours floor-heating cable or mats, less compelling if you just want a general-purpose smart thermostat.

Who It’s For

The nSpire Touch and SmartStat are built for electric radiant in-floor heating, not baseboards, forced-air, or wall heaters. If you’re installing or replacing a floor-heating system, especially one using WarmlyYours cable or mats, the floor-sensor integration and heating-cable-specific safety features make this a purpose-built match. If you have baseboard or convector heat instead, Mysa, Dimplex, or Cadet are the more relevant category.

Design & Build

The nSpire Touch is a touchscreen wall-mounted thermostat, while SmartStat is WarmlyYours’ separate programmable line, both aimed at the same in-floor heating use case. Home Depot reviewers describe setup as generally straightforward with an interface that’s easier to program than the company’s older non-Wi-Fi models. On the downside, some reviewers report the plastic housing and buttons feeling cheap, with a handful describing components breaking during installation itself, worth being careful with when mounting.

Setup & Compatibility

Both models are designed to pair with a floor sensor (included or sold alongside) that monitors slab or subfloor temperature directly, a feature specific to radiant floor heating rather than general line-voltage thermostats. Wiring is standard line-voltage for the heating cable circuit; Wi-Fi setup connects the thermostat to your home network for app access. If you’re installing new floor heating, WarmlyYours’ own installation guides and customer support (frequently cited as a strength in reviews) walk through pairing the thermostat correctly with your specific cable or mat product.

App & Ecosystem

WarmlyYours’ app supports basic scheduling and remote temperature control, plus Alexa and Google Assistant integration on current Wi-Fi models. We did not find confirmation of Apple HomeKit or Matter support. Reviewers consistently note the company’s customer service as responsive, which matters more than usual in this category since floor-heating thermostats involve more installation nuance (sensor placement, cable wattage matching) than a plug-and-play forced-air thermostat.

The Recommendation

Buy WarmlyYours if you’re installing electric radiant floor heating, especially with WarmlyYours cable or mats, and want a Wi-Fi thermostat matched to that system. Handle the plastic components carefully during install given the breakage complaints.

Skip it if you don’t have in-floor heating. For baseboard or convector heat, see Best Smart Thermostats for Electric Baseboard Heating.
