Emerson Sensi Touch ST75

The 46-comment pool (top 25 by upvotes shown) skews toward HVAC troubleshooting and comparison shopping rather than ST75 ownership itself. Direct product feedback is modest but consistent: owners say 'We love these thermostats' and one user states flatly, 'The Sensi is simple to setup and program hands down.' Complaints are concrete: the display face is black-only with no background color option ('I don't want an ugly black screen when the entire rest of my house is light colors'; the white side bezel 'doesn't help for the front'), no outdoor temperature or date display, and a structural limitation — 'there is no way to automatically prioritize a sensor during a schedule... You can select just the room sensor manually, but not automatically during a schedule.' An owner of the older Sensi ST55 reports it 'doesn't allow the option to schedule the system to be off only temp changes. No logging.' Reddit threads repeatedly push alternatives: Ecobee is credited with 'logging and a better geofencing implementation' (though the poster dislikes its look), and one HVAC pro warns that most Wi-Fi thermostats — citing the White-Rodgers 1F87U-42WF — 'chew through battery without a C-wire,' recommending a 5-wire run or an add-a-wire kit. Several Reddit comments are furnace diagnostics (bad inducer motor, error code 31) unrelated to the Sensi itself. Buyer questions cluster around dual-fuel compatibility (heat pump + gas furnace), migrating from Nest, temperature locking, lowest heating setpoint, and mounting footprint vs the non-touch Sensi with baseplate.
