Cielo Breez Max vs Honeywell Home T9 Smart Thermostat

The Honeywell Home T9 Smart Thermostat wins overall, ahead on warranty, included accessories, integrations, sensors, alerts and its built-in speaker. The Cielo Breez Max keeps a lower price, a higher owner rating and wider connectivity, but the two control different kinds of HVAC equipment.

The Honeywell Home T9 Smart Thermostat is a wired thermostat for a ducted furnace or heat pump. The Cielo Breez Max is an infrared controller for a ductless mini-split, window unit or portable air conditioner, with no wiring into a furnace at all.

No. The Honeywell Home T9 Smart Thermostat ships with a wireless Smart Room Sensor rated up to 200 feet, and supports adding more. The Cielo Breez Max has no support for external temperature sensors at all.

The Honeywell Home T9 Smart Thermostat does, for audio feedback and voice responses. The Cielo Breez Max has no speaker, though it does answer Alexa, Google Assistant and Siri Shortcuts commands.

Homes with a standard ducted furnace or heat pump and rooms that run hot or cold, since the bundled Smart Room Sensor is built specifically to fix that problem.

Anyone cooling or heating a room with a ductless mini-split, window unit or portable air conditioner that came with an infrared remote, since the Honeywell Home T9 Smart Thermostat cannot control that kind of system.
