Could you build this?
No This is physical HVAC smart thermostat hardware involving custom PCB design, 24VAC relays, RF/WiFi radio protocols, and strict electrical safety certifications.
What it would actually take: Developing this product involves electrical engineering for 24VAC HVAC power-stealing circuits and relay switching (supporting 4H/2C stages), custom embedded firmware (e.g., ESP32 or Nordic nRF) managing low-power sub-GHz RF communication with 10 remote room sensors, and hardware certifications like FCC and UL.
