Side-by-Side Comparison
| Spec | Sensi Touch 2 (ST76) | ecobee Smart Thermostat Premium (EB-STATE6-01) |
|---|---|---|
| Price | $189.00 | $259.99 |
| Release Year | 2022 | 2022 |
| System Voltage | Low voltage 24VAC — gas, oil, electric, heat pump, boilers. Not for 120/240V line-voltage heat | Low voltage 24VAC — furnaces, air conditioners, heat pumps, boilers, PTAC and fan coil units. Not for 120/240V line-voltage heat |
| C-Wire Required | Yes. Copeland's spec sheet requires 20-30VAC between RH/RC and C, and every retail listing is labelled 'C-Wire Required' | Not in practice. ecobee ships the Power Extender Kit in the box, which synthesises a common wire from R, W, Y and G at the furnace. Direct wiring uses C and Rc if you do have five wires |
| Adapter / Power Kit Included | No — the Sensi C-Wire Kit is a separate purchase at roughly $28 | Yes — Power Extender Kit included. The same kit is a $24.99 extra on the Essential |
| Heating & Cooling Stages | 1H/1C, 2H/2C multi-stage, and up to 4H/2C on heat pumps | 2H/2C conventional; boilers, PTAC and fan coil units with up to 3 fan speeds |
| Heat Pump & Aux Heat | Yes — up to 4 heat and 2 cool including auxiliary stages, the widest heat-pump staging here alongside the ecobee Premium | Yes — heat pump 2H/2C plus 2 stages of auxiliary heat, the deepest heat-pump staging in this set |
| Humidifier / Ventilator Terminals | ACC+/ACC- terminals drive a humidifier or dehumidifier, with a humidify range of 5-50% RH and dehumidify 40-95% RH | One 1-wire or one 2-wire accessory on the ACC+/ACC− terminals: humidifier, dehumidifier or HRV/ERV ventilator |
| Remote Sensors | Sensi Room Sensors at about $40 each, sold separately. Copeland states only the Touch 2 (ST76 / 1F96U series) supports them and does not publish a maximum count | One SmartSensor in the box; up to 32 pair, over a 915MHz radio at up to 60 ft. Extra sensors are $99.99 for a 2-pack |
| Occupancy Detection | None. TechHive's review notes the Sensi Room Sensor reads ambient temperature and humidity and has no motion detection, unlike competitors' sensors | Radar occupancy and proximity in the thermostat, and every SmartSensor also detects occupancy over a 140° x 100° field to about 20 ft |
| Matter Support | No. TechHive states the Touch 2 supports neither Matter nor Apple HomeKit | Not shipping on this model. ecobee's own spec page lists HomeKit, Alexa, Google Assistant, SmartThings and IFTTT and never mentions Matter; third-party write-ups describe a phased rollout, so treat Matter as unconfirmed here |
| Voice & Smart Home Platforms | Sensi app, Amazon Alexa, Google Assistant and Samsung SmartThings. No Apple Home | Apple HomeKit with Siri, Alexa built in (speaker and microphone), Google Assistant, Samsung SmartThings, IFTTT |
| Utility Rebates & Demand Response | ENERGY STAR certified; Copeland runs Sensi demand-response partnerships with utilities and the thermostat is widely rebated | eco+ Community Energy Savings with 150+ North American utilities. ecobee states events move your temperature 1-4°F for no more than a few hours, a handful of times a year, and you can opt out of any event from the app; some programs pay an enrolment rebate up to $125 |
| Account or Subscription Needed | No subscription, and Copeland markets an explicit 'we do not sell your data' privacy position | No subscription for eco+, energy reports, remote sensors or scheduling. ecobee Smart Security — the intrusion-monitoring layer on the same hardware — is the paid tier |
| Warranty | 36 months | 36 months |
| Colors | Black (ST76), White beveled edge (ST76W) | Black |

Pros & Cons
Sensi Touch 2 (ST76)
Pros
- +4H/2C heat pump staging plus humidifier and dehumidifier terminals — genuinely serious HVAC coverage for under $200
- +3-year warranty and a published privacy stance that no other brand here makes explicit
- +Street price has settled around $189 against a $209.99 list, and it periodically drops much further
- +Real multi-stage and dual-fuel handling that the similarly priced Nest Thermostat and ecobee Essential do not offer
Cons
- −No Matter and no Apple HomeKit — the Touch 2 dropped the HomeKit support the original Sensi Touch had
- −C wire required and the C-Wire Kit is a ~$28 extra, where ecobee includes an equivalent kit free
- −Sensi Room Sensors are $40 each, sold separately, and detect temperature and humidity only — no occupancy
- −No decorative trim plate in the box, so old paint outlines and screw holes show
- −Copeland does not publish how many room sensors can pair, which makes planning a multi-room setup guesswork
ecobee Smart Thermostat Premium (EB-STATE6-01)
Pros
- +The Power Extender Kit is in the box, so the C-wire problem is solved at purchase rather than at $25 extra or a $200 electrician call
- +Heat pump 2H/2C plus two auxiliary stages beats every other thermostat here on staging depth
- +SmartSensors detect occupancy as well as temperature — Google's, Honeywell's cheaper models' and Sensi's sensors mostly do not
- +Built-in speaker and mic make it a working Alexa device, and it doubles as an ecobee Smart Security hub
- +3-year warranty, a year longer than Google and Resideo
Cons
- −No Matter. ecobee's own spec sheet lists HomeKit, Alexa, Google, SmartThings and IFTTT and nothing else, which is a strange gap on a $260 flagship in 2026
- −$259.99 is the second-highest price here and it went up — ecobee has quietly raised list prices across the range
- −The air-quality monitor produces a score and advice, not a calibrated PM2.5 or VOC reading you can act on
- −Alexa built in means an always-listening mic on your hallway wall, with no hardware mute switch of the kind Echo speakers have
- −Only one accessory circuit — a humidifier and an ERV cannot both be wired at once
