Paperback. Condición: new. Paperback. Build reliable Lua firmware for ESP8266 and ESP32 that ships, updates, and runs for months without fuss.Developers run into tight RAM, fragile Wi-Fi, and brittle updates when small devices meet real homes. This book gives you a practical workflow to choose the right ESP boards, keep heaps st…able, and move code into flash so your nodes stay responsive.You will set up a lean toolchain, flash clean images, and structure Lua the way production devices need it, from sensor reads to secure messaging and Home Assistant integration.Pick ESP8266, ESP32 C3, S3, or C6 with clear RAM, flash, radio, and power tradeoffsInstall Python tools, drivers, esptool, and a dependable serial console on any OSBuild tight NodeMCU firmware, prune modules, and use LFS to keep code in flashUnderstand GC behavior, configure pause and step multipliers, and prevent heap spikesUse tmr, file, node, wifi, net, mqtt, tls, sjson for stable event driven codeChoose SPIFFS or LittleFS wisely, migrate safely, and avoid wear issuesStage boot flow with init.lua, safe mode, and staged startup loadersPerform Lua OTA with HTTP pull, verify images, and implement clean rollbackConfigure Wi-Fi profiles with static IP and BSSID for fast reconnect after sleepStream sockets and HTTP without big buffers, size TLS records, handle certsDesign MQTT lifecycles with keepalive, LWT, retain strategy, and backoffIntegrate with Home Assistant using MQTT Discovery topics and payload templatesWire DS18B20, BME280, SHT3x, relays, MOSFETs, and PWM dimmers with robust retries and safetyHandle analog inputs on ESP chips, avoid reference pitfalls, and validate readingsPlan deep sleep, wake sources, static IP, and BSSID cache for battery lifeBudget power, measure real current, and estimate device life with a simple scriptSecure traffic with TLS settings that fit in RAM, or apply PSK with rotation plansUse ESP32 OTA partitions and rollback flow for firmware updates that recoverProvision unique credentials per device and expose a clear recovery modeTroubleshoot heap and GC under TLS and JSON load, prevent brownouts and boot loopsCapture crashes and field logs, toggle safe mode with remote flags, and set guardrailsKnow when NodeMCU is not the right tool and what alternatives to pickApply end to end tests from device to broker to Home Assistant dashboardsIncludes field ready case studies, a production checklist, security review steps, update playbooks, and rollback drills you can run on the bench before you ship.This is a code heavy guide with working Lua snippets, esptool commands, and MQTT payloads you can paste, adapt, and deploy to real devices.Grab your copy today.
