In this part of the video, the reviewer discusses upgrading to the CT50 Wi-Fi Radio Thermostat from an older, basic thermostat. They highlight the desire to integrate the new thermostat into their Molino IoT framework, avoiding the default cloud interface for privacy reasons. The CT50 was chosen for its open API allowing updates and control via HTTP requests, and it is considered a good value at $100. Features mentioned include a large touchscreen, a lack of a mounting bracket, two expansion slots, and a Wi-Fi module. The reviewer notes challenges with Wi-Fi setup due to the lack of instructions in the box. The thermostat supports multi-state HVAC systems but requires a common c-wire, which differs from the older thermostat that used a simpler four-wire setup and power-stealing technique.

In this part of the video, the focus is on the importance of a common wire for Wi-Fi functionality in HVAC systems. The speaker explains that while batteries can keep the system running if power is lost, the Wi-Fi will not work without a common wire. Instead of purchasing a new, expensive cable with more wires, the speaker opted to run an additional wire alongside the existing one to connect the common wire from the HVAC controller. Alternatively, repurposing the fan wire for the common wire is suggested if running a new wire is challenging, though it sacrifices independent fan control. Moreover, the speaker integrates a Wi-Fi thermostat into a dashboard by creating a specific thermostat node to pull data via a REST API, enabling remote control and monitoring. The interaction shows a slight delay in interface updates, typically 2-3 seconds, while ensuring synchronization between the thermostat and the home automation system. Additionally, some teardown photos of the thermostat components are shared.
