I already have an ESP32 reading voltage, current, power, and total consumption from a PZEM-004T energy-meter module inside my UMA smart-home demo. What I need next is the mobile front end—and a touch of intelligence—so users can actually benefit from all that data. Here is what I’m after: the app must show real-time readings streamed over Wi-Fi, store those readings so I can browse days or weeks of historical data, and raise push notifications whenever usage crosses adjustable thresholds. Visualisation should be clear, attractive graphs and charts rather than raw numbers. Beyond monitoring, I want the system to react on its own: if consumption spikes or falls outside a range I’ll define, the ESP32 should trigger automated adjustments to the connected fan and light (for example dimming, speed changes, or temporary cut-off) without users having to intervene. Manual on/off toggles or rigid schedules are not required at this stage. Please build the mobile app (cross-platform is ideal, but I’m open) and deliver clean, well-documented source code plus any firmware tweaks needed on the ESP32 so the control loop is seamless. MQTT, WebSocket, or HTTP can all work; choose what you are most comfortable with as long as latency stays low and the code is easy to expand later. A short README outlining setup, compilation, and how to add new appliances will complete the job. If the above sounds clear, let’s get started—I’m ready to test the first build as soon as you can push it.
