The short version: The Sensi Touch 2 (model ST76) is the updated generation of Sensi’s touchscreen line: a redesigned beveled-edge look, an improved interface, and — for the first time in the Sensi lineup — support for remote room sensors, sold separately. Multiple independent outlets reviewed it favorably, and street pricing regularly undercuts ecobee’s Premium and Nest’s Learning Thermostat by close to $100. It’s the strongest all-around Sensi model if you want more than the base ST75.

Who It’s For

The Sensi Touch 2 fits:
– Forced-air homes wanting a modern touchscreen thermostat without ecobee/Nest pricing
– Buyers who want room-sensor flexibility without paying ecobee-sensor prices, though Sensi’s sensor ecosystem is newer and smaller
– Alexa or Google Home households

It’s a step up from the original Sensi Touch ST75 in design and features, so if you’re deciding between the two, the Touch 2’s added sensor support and refreshed interface are the main reasons to pay more.

Design & Build

The Touch 2 uses a more streamlined beveled-edge design compared to the original ST75, described by reviewers as a genuine visual upgrade. The touchscreen interface is also improved — testers report the app-to-thermostat sync working smoothly, without the lag or “lost connection” issues that plague some competitors when adjusting from the wall unit right after changing something in the app.

Setup & Compatibility

Like the ST75, the Sensi Touch 2 requires a C-wire for continuous power. Installation follows the same pattern as the rest of the Sensi lineup: app-guided wire labeling and terminal matching, typically 30-45 minutes for a DIY install. It covers most single and dual-stage forced-air systems including heat pumps. Check Sensi’s compatibility tool before buying if your system is non-standard.

App & Ecosystem

The Sensi app on the Touch 2 handles scheduling smoothly — reviewers specifically call out that changes made remotely apply quickly and reliably, without the app “losing” the thermostat, a real complaint on some competing budget thermostats.

Ecosystem support:
– Amazon Alexa — voice control
– Google Assistant — voice control
– Apple HomeKit — supported

Room Sensors: New for This Generation

The Sensi Touch 2 is the first Sensi model to support remote room sensors, sold separately rather than bundled. This narrows the gap with ecobee’s SmartSensor system, though Sensi’s sensor lineup is newer and less established — fewer accessories, less third-party integration, and a shorter track record than ecobee’s. If room-level comfort is your main reason for upgrading, weigh the Touch 2’s sensor pricing and availability against ecobee’s before committing, since ecobee remains the more mature ecosystem here.

Price & Value

Item Price (USD)
Sensi Touch 2 ~$160-210 (MSRP ~$210, frequently discounted lower)
ecobee Premium (for comparison) ~$330
Nest Learning Thermostat 3rd Gen (for comparison) ~$220-250

Reviewers have specifically flagged the Touch 2’s street price as notably lower than ecobee Premium and Nest Learning Thermostat while covering comparable core functionality (though not matching ecobee’s full sensor ecosystem or Nest’s auto-learning). For buyers who want a touchscreen and don’t need best-in-class sensors, it’s a genuine value pick.

Pros & Cons

Pros:
– Refreshed, more polished design than the original ST75
– Smooth, reliable app-to-device sync
– First Sensi model with room sensor support
– Priced well below ecobee Premium and Nest Learning Thermostat
– HomeKit, Alexa, and Google Assistant support

Cons:
– C-wire required
– Sensor ecosystem is new and smaller than ecobee’s
– Sensors sold separately, adding to total cost if you want room coverage

The Recommendation

Buy the Sensi Touch 2 if you want a modern touchscreen thermostat with room-sensor flexibility at well below ecobee/Nest pricing. If you don’t need sensors, the original Sensi Touch ST75 is cheaper and covers the same core ground. If sensor maturity and ecosystem breadth matter more than price, ecobee’s Premium is still the stronger pick.
