The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
The Sensi Touch ST75 emerges from the reviewer pool as the quiet workhorse pick. Reviewed.com (high-trust) calls the Touch 2 generation 'a good choice for smart homes looking for an intuitive option,' PCMag praises the touchscreen and multi-platform support, and CNET's verdict frames it as a 'good smart thermostat' with a responsive app. Crucially, in r/HVAC and r/smarthome — community sources we treat as high-trust on installation reliability — an HVAC installer calls Nest 'complete trash' relative to Sensi, and another long-time user describes the Touch as 'rock solid' since 2020.
What reviewers liked
- High-trust endorsement from Reviewed.com and corroborating PCMag/CNET reviews
- Energy Star certified, eligible for most utility rebate programs
- HVAC professionals on Reddit specifically prefer it over Nest for reliability
- Strongest customer rating in the pool: 4.5 stars across 14,000+ Amazon reviews
- Touchscreen color display and multi-platform voice support (Alexa, Google, HomeKit per PCMag)
Where it falls short
- Requires a C-wire, ruling out some older installations
- Cloud-dependent integration; r/homeassistant users note no local control
- Industrial styling is less attractive than Nest or ecobee per reviewer commentary
- Feature set is less sophisticated than premium-tier ecobee or Nest Learning models
The Sensi Touch ST75 emerges from the reviewer pool as the quiet workhorse pick. Reviewed.com (high-trust) calls the Touch 2 generation 'a good choice for smart homes looking for an intuitive option,' PCMag praises the touchscreen and multi-platform support, and CNET's verdict frames it as a 'good smart thermostat' with a responsive app. Crucially, in r/HVAC and r/smarthome — community sources we treat as high-trust on installation reliability — an HVAC installer calls Nest 'complete trash' relative to Sensi, and another long-time user describes the Touch as 'rock solid' since 2020.
It is also Energy Star certified, which is the qualifying line most U.S. utility rebate programs draw, and the price ($117) means rebates frequently bring the net cost to near zero. The 4.5 / 14,000+ Amazon rating is the strongest in this candidate pool and is corroborated by the expert and community signals rather than standing alone.
The honest caveats: the Touch requires a C-wire, the design is more functional than fashionable, and r/homeassistant users note that integration depends on Sensi's cloud rather than running locally. Reviewers do not describe it as exciting — they describe it as reliable, which is precisely why it ranks this high.

The Sensi Touch ST75 is a smart thermostat you can control with your phone, voice, and a color touch-screen panel. It offers temperature and humidity alerts and usage reports, as well as support for several smart home platforms.
No matter the season, you want to be able to keep your house comfortable—cool in summer, warm in winter. The Sensi Touch 2 (function ga4_link5() { window.dataLayer.push(JSON.parse('{"event":"click_affiliate","affiliate_merchant":"Amazon","affiliate_network":"AmazonStack","link_location":"inline_affiliate"}')) }available at Amazon for $147.90) can help you do just that—it is one of the function ga4_link6() {…
I tried both for a while before making my final decision and the Nest is complete trash. It's like a Wish.com version of a "smart" thermostat.
