ESP32 Smart Plug Prototype

I’m building a proof-of-concept that lets an ESP32 watch four household-appliance plugs, detect when any one of them draws power, and immediately hit a specific URL over Wi-Fi. Scope • Each plug must be monitored independently. • For every event I need to log power consumption and, as an extra data point, the real-time voltage level. • As soon as a plug’s load goes above a configurable threshold the firmware should perform an HTTP/HTTPS GET (or POST if that’s easier) to the URL I provide, passing the plug ID, watts, and voltage in the query/body. • Connection details (SSID, password, endpoint URL, thresholds) should be editable in code and preferably via a simple serial menu or captive portal. Deliverables 1. Well-commented ESP32 firmware 2. Schematic and parts list showing how you sense current and voltage for four mains outlets safely 3. Brief setup guide so I can flash, wire, and test the prototype on my bench. Acceptance criteria The job is complete when I can power up the board, connect it to my Wi-Fi, plug in a household device, see voltage and wattage reported correctly, and watch the HTTP call arrive with the right JSON/query string.
