One reviewer liked the included trim plate for covering wall blemishes behind the thermostat.
Pros: conventional HVAC compatibility, touchscreen responsiveness
Cons: presence-based automation
The included mounting/back plate was useful for fitting existing holes or covering wall imperfections during installation.
Pros: temperature accuracy, Apple Home/HomeKit support
Cons: shared household access, touchscreen responsiveness
Wall mounting was mostly acceptable, with one reviewer finding the bracket sturdy and another preferring the cleaner look without a back plate.
Pros: Wi-Fi stability, Apple Home/HomeKit support
Cons: utility demand-response support, HVAC system compatibility depth
The Honeywell UWP connection makes swaps and future upgrades especially easy for compatible homes. One used unit had broken retaining clips and would not stay secured to the wall plate.
Pros: presence-based automation, simplicity
Cons: included C-wire adapter, reconnection reliability after outages
Wall fit is context-dependent: one review warned uncovered holes can look bad, while another liked the trim kit’s ability to keep the wall neat.
Pros: temperature accuracy, humidity sensing
Cons: included C-wire adapter, Matter support
Wall fit can be imperfect when replacing a larger thermostat because the smaller base may leave visible unpainted edges.
Pros: comfort consistency, privacy controls
Cons: heat pump compatibility, included C-wire adapter
