- Low-Code embedded IoT with ZapierBuild Secure MQTT Workflows on Raspberry Pi, ESP32, and Cloud APIsby Devlin AshorBuild connected products without reinventing core plumbing. This practical guide shows how to move device data from MQTT to the cloud, trigger reliable automations with Zapier, and keep the entire path observable and resilient. You will wire up Raspberry Pi and ESP32 boards, structure topics for scale, stream telemetry into spreadsheets and databases, and route alerts to chat and SMS. Each chapter ends with a lab that reinforces concepts through a working, testable outcome.Instead of heavy frameworks, you will use small Python or JavaScript snippets where they matter and lean on managed services everywhere else. Along the way you will add OTA update guardrails, audit trails, redaction rules, key rotation, and rollback plans so your prototype grows into a maintainable system. The result is a production-ready pipeline that your team can understand, operate, and evolve with confidence.What You’ll Learn Device Onboarding: Issue claim tokens, enroll devices, and capture registration audits with operator and time.MQTT Topic Design: Standardize telemetry, command, and heartbeat topics for fleets and tenants.Reliable Telemetry: Batch writes, apply backpressure, and design idempotent upserts for clean data.Data Ingestion: Validate webhooks, map JSON payloads, and append rows to Sheets, BigQuery, and Postgres. Alerting Patterns: Use thresholds with hysteresis, debounce noisy sensors, and build escalation windows with quiet hours.Enrichment and Transforms: Normalize units, call third-party APIs for context, and cache results with TTL rules. Security and Governance: Model roles for humans, services, and devices; redact logs; rotate keys; add gate checks.Observability: Trace events end-to-end with OpenTelemetry and replay messages safely during incidents. Operations at Scale: Enforce tenant quotas, run rollback runbooks, and maintain schema compatibility.Cost and Reliability: Set request budgets with sampling, define golden sets, and monitor SLOs from a weekly dashboard.Who This Book Is ForEngineers, makers, and ops teams who want working IoT pipelines without heavy custom infrastructure. If you can flash an ESP32, run Docker, and read basic Python or JavaScript, you are ready. Product managers and solution architects will also benefit from the clear patterns, guardrails, and checklists that translate prototypes into dependable servicesWhy You Should Get This Book Now Low-code automation has matured to the point where small teams can deliver secure, observable IoT systems quickly. This book compresses months of trial and error into a tested set of patterns, templates, and labs. You will avoid common pitfalls, scale with confidence, and keep costs in check while staying close to the hardware and the data your users care about most.The tools are accessible. The patterns are proven. This guide shows you how to put them together the right way.Ship faster, operate safer, and grow from prototype to production with Low-Code embedded IoT with Zapier.
