Installing the Honeywell T6 Pro was surprisingly straightforward—until I hit a snag with the wiring. My old system didn’t have the blue power wire, which left me scrambling. Thankfully, Resideo’s tech support was a lifesaver, walking me through a workaround. Once it was up and running, the thermostat felt sleek and modern, blending right into my home.

Energy savings kicked in almost immediately. I noticed my heating bills dropping within weeks, which was a huge win. But then came summer, and the air conditioning feature started acting up. The thermostat got stuck at 77°F, turning my living room into a sauna. Customer service? Useless. I ended up paying my HVAC guy just to shrug at it.

Would I recommend it? Maybe—if your wiring is compatible and you’re okay rolling the dice on long-term reliability. For me, it’s been equal parts ‘smart home dream’ and ‘midnight troubleshooting nightmare.’
