Could you build this?
No This is a physical IoT hardware device involving microcontrollers, fluid pumps, power electronics, and HVAC plumbing.
What it would actually take: The product requires an embedded system (ESP32 or RP2040) running C++/FreeRTOS firmware, a 12V peristaltic dosing pump, liquid level sensors, and a relay/MOSFET driver board. The hard challenges lie in chemical-resistant hardware design (handling acetic acid/vinegar corrosion), reliable power regulation in an attic/HVAC environment, and custom mechanical fittings for condensate PVC lines. Requires mechanical, electrical, and embedded firmware engineering.
