Thermostats with no Wi-Fi

A thermostat controls your heating and cooling, so many people would rather it didn't depend on a cloud service. These programmable models keep their schedule on the device and are set from the buttons on the front.

Not yet verified / not listed

These models are not on the verified list. Either we couldn't confirm they're currently sold, or the spec page was ambiguous.

  • Honeywell Home X1N (RTH11B) non-programmable: Honeywell's spec page lists no Wi-Fi, but we didn't find it at a major retailer on Oct 25, 2026. (source)
  • Honeywell Home T4 Pro (TH4110U2005): Honeywell spec: WiFi: No. Sold mainly through professionals, and Home Depot lists it under another brand name, so retail availability isn't clear. (source)
  • Honeywell Home T5 7-Day Programmable (RTH7560E): Excluded: Honeywell's spec table for this listing says WiFi: Yes, which doesn't match how retailers describe it. Left off until it's clear. (source)
  • Others (Emerson/Copeland, Braeburn, AprilAire) : Not checked yet.

Notes

Before you buy: check your wiring and system type (single-stage, multistage, heat pump, or line-voltage baseboard). Line-voltage baseboard heaters need a different kind of thermostat.

Retailer listings use the trailing letters differently (e.g. RTH20B/N at Home Depot). The model family is what matters.
