Verify every terminal, transformer, stage, auxiliary transition, local control, account transfer and return or installer-service term before purchase.
Current market
Each line carries its own check date because price, software, specifications, and product cycle do not age at the same speed.
Security subscriptions, additional SmartSensors, professional rewiring and HVAC accessories are separate. Confirm current stock, authorized U.S. seller, included hardware, tax, shipping, return rights and installation before paying.
Premium is the defended all-round conventional choice when its terminal map, room sensor and accessory outputs fit the equipment and the household accepts ecobee account and cloud services.

What changed
Older observations stay in the ledger when the current view changes. That lets a buyer tell the difference between an old complaint, an active issue, and a problem that was corrected.
Smart Thermostat Premium was checked against exact identity and support, current U.S. price, topology, stages, power, heat-pump, sensors, app, offline, demand-response, installation, service and outcome boundaries, independent decision evidence and bounded owner or installer reports.
Each amount stays tied to its source and capture date. Conflicting prices remain visible until the seller resolves them.

Owner experience
Owner and installer discussion returns to terminal compatibility, pek limits, room-sensor placement, heat-pump thresholds, firmware and support rather than a universal comfort, savings or reliability result.
These are self-reported experiences from different HVAC equipment, wiring, transformers, zones, homes, climates, setpoints, tariffs, networks, firmware, apps, utility programs, installers and maintenance histories. They identify checks to run and do not establish comfort, savings, temperature accuracy, air quality, fault diagnosis, safety, freeze protection, reliability or failure rates.Self-selected owners and technicians discuss PEK wiring, heat-pump thresholds, sensors, app behavior, firmware and support. Reports are configuration-specific and do not establish savings, comfort or reliability rates.
Export the equipment settings, verify every stage and auxiliary transition with the installer and test sensor priorities before relying on automation.

ecobee identifies EB-STATE6-01 as a 24 VAC conventional control with an included SmartSensor, occupancy features, voice hardware and accessory terminals for broad furnace, boiler and heat-pump applications.
$259.99 current U.S. direct price was retained for EB-STATE6-01. Security subscriptions, additional SmartSensors, professional rewiring and HVAC accessories are separate
Conventional 24 VAC relay control for gas, oil and electric furnaces, boilers, air conditioning and heat pumps; it is not compatible with line-voltage heat or proprietary communicating terminals Supports up to 2 heat/2 cool conventional or 4 heat/2 cool heat pump, plus configured humidifier, dehumidifier or ventilator paths subject to terminal use Auxiliary and emergency heat, compressor-to-aux staging and dual-fuel operation require correct O/B, fuel, fan and threshold configuration; the thermostat does not make an incompatible furnace and heat pump into a valid dual-fuel system A dedicated C-wire is preferred; the included PEK supports documented forced-air layouts with compatible R, G, Y and W wiring, not arbitrary two-wire or millivolt systems One wireless temperature and occupancy SmartSensor is included and more can be averaged or scheduled; room sensors do not create duct zones or control dampers independently
The ecobee app, account, Wi-Fi, remote access, weather, voice services and optional home-monitoring features process household, device, occupancy and usage data under ecobee and linked-platform policies The wall control and stored schedule retain basic thermostat operation during an internet loss, while app, voice, weather, geofence, history, remote support and demand-response services need the connected path The direct hardware warranty is three years under stated conditions. No thermostat, sensor, schedule or savings claim guarantees room comfort, even temperatures, energy savings, equipment life, freeze protection or utility eligibility
Certified connected thermostats must retain basic thermostat operation without service-provider connectivity, support schedules and report energy-use information; certification is not a household comfort or savings guarantee.
EPA directs buyers to match HVAC type, voltage, wires, variable speed, stages and zoning before purchase and notes that line-voltage and complex systems often require specialized controls or professional installation.
Heat-pump performance depends on the complete equipment and controls; thermostat stage or app labels do not establish capacity, auxiliary-heat economics, dual-fuel operation or delivered comfort.
FTC consumer guidance covers router security, unique passwords, updates and privacy settings for connected devices; cloud convenience does not remove household security and access duties.
Current hands-on comparison retains Smart Thermostat Premium and evaluates installation, room sensing, interface, ecosystem and value against Nest and Honeywell options.
Self-selected owners and technicians discuss PEK wiring, heat-pump thresholds, sensors, app behavior, firmware and support. Reports are configuration-specific and do not establish savings, comfort or reliability rates.
Honeywell Home X8S Smart Thermostat is the large-display premium conventional control defended alternative at $219.99 current U.S. direct price.
Nest Learning Thermostat, 4th gen is the premium learning and google home control defended alternative at $279.99 regular U.S. direct price.
Manufacturer identity, exact product or support documentation, current U.S. price, independent decision evidence and bounded owner or installer evidence were checked on August 19, 2026. This desk covers complete current U.S.-supported residential thermostat and HVAC-control systems where conventional low-voltage relays, proprietary communicating control, line-voltage electric heat, radiant-floor control or mini-split infrared retrofit materially changes the decision. It excludes bare sensors, faceplates, cosmetic finishes, multipacks, dealer software licenses, unsupported prior generations, portable-heater controls and smoke or carbon-monoxide life-safety alarms. Voltage, transformer, terminals, stages, heat-pump, auxiliary, emergency-heat, dual-fuel, proprietary-bus, accessory, zoning and sensor limits are exact-model facts. A room sensor can influence one equipment zone without creating duct zoning. Mini-split IR controllers can miss commands or lose state when the native remote is used and cannot override shared-outdoor-unit mode limits. Local wall control and stored schedules differ from app, voice, weather, geofence, history, firmware and demand-response services that require accounts, cloud and connectivity. Demand-response enrollment is voluntary and utility-specific. Turn off equipment power and use a qualified HVAC technician or electrician for uncertain low-voltage, communicating, dual-transformer, line-voltage, wet-area or multi-equipment work. Compressor delays, balance points, stage timing, O/B, fan, fuel and dual-fuel settings must match the equipment manual. Alerts, temperature, humidity, TVOC and CO2-equivalent readings are not equipment diagnosis, source identification, health diagnosis or safety clearance and do not replace smoke and CO alarms. No thermostat or control guarantees comfort, even rooms, energy savings, utility rewards, freeze protection, equipment life, fault prevention or uninterrupted service.
