Verdict: These devices serve fundamentally different purposes—one secures entry points while the other manages HVAC—so direct comparison is limited. The ecobee Smart Thermostat Premium scores higher overall due to advanced sensors and energy features per CNET and Wirecutter reviews. August Wi-Fi Smart Lock 4th Gen excels only for targeted door access but trails in longevity without a C-wire equivalent.
