Side-by-Side Comparison
| Spec | ecobee Smart Thermostat Enhanced (EB-STATE6L-01) | Sensi Touch 2 (ST76) |
|---|---|---|
| Price | $199.99 | $189.00 |
| Release Year | 2022 | 2022 |
| System Voltage | Low voltage 24VAC — furnaces, air conditioners, heat pumps, boilers, PTAC and fan coil units. Not for 120/240V line-voltage heat | Low voltage 24VAC — gas, oil, electric, heat pump, boilers. Not for 120/240V line-voltage heat |
| C-Wire Required | Not in practice — the Power Extender Kit is included and creates a common wire from R, W, Y and G | Yes. Copeland's spec sheet requires 20-30VAC between RH/RC and C, and every retail listing is labelled 'C-Wire Required' |
| Adapter / Power Kit Included | Yes — Power Extender Kit included in the box | No — the Sensi C-Wire Kit is a separate purchase at roughly $28 |
| Heating & Cooling Stages | 2H/2C conventional; boilers, PTAC and fan coil units | 1H/1C, 2H/2C multi-stage, and up to 4H/2C on heat pumps |
| Heat Pump & Aux Heat | Yes — heat pump 2H/2C plus 1 stage of auxiliary heat (the Premium gets 2) | Yes — up to 4 heat and 2 cool including auxiliary stages, the widest heat-pump staging here alongside the ecobee Premium |
| Humidifier / Ventilator Terminals | One 1-wire accessory: humidifier, dehumidifier or HRV/ERV ventilator. The Premium's 2-wire option is not available here | ACC+/ACC- terminals drive a humidifier or dehumidifier, with a humidify range of 5-50% RH and dehumidify 40-95% RH |
| Remote Sensors | None in the box. Up to 32 SmartSensors pair, sold separately at $99.99 for a 2-pack | 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 |
| Occupancy Detection | Radar occupancy and proximity in the thermostat. Room-level occupancy needs SmartSensors you have to buy | None. TechHive's review notes the Sensi Room Sensor reads ambient temperature and humidity and has no motion detection, unlike competitors' sensors |
| Matter Support | Not listed on ecobee's spec page for this model | No. TechHive states the Touch 2 supports neither Matter nor Apple HomeKit |
| Voice & Smart Home Platforms | Apple HomeKit with Siri, Amazon Alexa, Samsung SmartThings and IFTTT are what ecobee's spec page lists; ecobee's retail listing also claims Google Assistant. No built-in microphone or speaker | Sensi app, Amazon Alexa, Google Assistant and Samsung SmartThings. No Apple Home |
| Utility Rebates & Demand Response | eco+ Community Energy Savings with 150+ utilities; enrolled events shift your temperature 1-4°F for a few hours a handful of times a year, opt-out per event | ENERGY STAR certified; Copeland runs Sensi demand-response partnerships with utilities and the thermostat is widely rebated |
| Account or Subscription Needed | No subscription. A free ecobee account is required | No subscription, and Copeland markets an explicit 'we do not sell your data' privacy position |
| Warranty | 36 months | 36 months |
| Colors | Black | Black (ST76), White beveled edge (ST76W) |

Pros & Cons
ecobee Smart Thermostat Enhanced (EB-STATE6L-01)
Pros
- +Same screen, same radar occupancy sensor and the same in-the-box Power Extender Kit as the $259.99 Premium, for $60 less
- +Handles heat pump 2H/2C with aux, which is more staging than the Nest Thermostat, X2S, Sensi Lite or Amazon can manage
- +Still takes 32 occupancy-sensing SmartSensors if you add them later
- +3-year warranty
Cons
- −No SmartSensor in the box — buy one and the price gap to the Premium closes to almost nothing
- −No air quality monitor, no speaker and no built-in Alexa or Siri voice
- −One auxiliary heat stage instead of the Premium's two, which matters on cold-climate heat pumps
- −No Matter on ecobee's spec list, so Matter-only smart home setups are out
- −Only one 1-wire accessory circuit, so a humidifier and a ventilator cannot both be driven
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
