What does the $79.99 Amazon option require?
According to Amazon, the Amazon Smart Thermostat is built with Honeywell Home technology and works with Alexa and Ring Amazon product listing. It needs a C-wire to supply steady power. Many newer forced-air systems include one, while older wiring may lack it.
This option suits renters and owners who already use Alexa for voice control. It suits shoppers who want simple scheduling without learning features. Confirm C-wire presence at your furnace or wall plate before ordering.
Why are room-sensor choices limited?
According to Honeywell Home, the T9 Smart Thermostat with sensor lists at $209.99 but shows sold out and no longer available for sale Honeywell Home product page. That status removes one sensor-based pick from Cyber Monday shelves. Shoppers who want per-room temperature balancing lose an option.
If room sensors matter to you, compare current Nest sensor support and in-stock bundles. Check package contents, sensor count, and return terms before switching brands. Do not assume a third-party sensor pairs with every system.
