ESP32 & IoT

Twelve parts on getting a sensor reading off your bench and onto a dashboard — Wi-Fi that reconnects, MQTT that survives a reboot, and power that lasts.

The ESP32 makes it easy to put a sensor on Wi-Fi and hard to keep it there. This track covers the parts that decide whether an IoT build lasts a weekend or a year: reconnect logic, brownouts under radio load, deep sleep and wake sources, MQTT retention, and OTA updates you can actually roll back.
