LightwaveRF + ESP32 • Lights + Oil Tank Level

Modern home automation
with LightwaveRF + ESP32

A practical, resilient setup: LightwaveRF handles reliable mains lighting control, while an ESP32 adds local intelligence—sensors, automation logic, and integrations—without needing a full server 24/7.

What this setup delivers

simple • expandable • maintainable
Lighting control
Instant + familiar
Keep normal switches; add scenes, schedules, and presence rules.
Oil management
Level → alerts
Track % remaining, predict runout, and notify before it’s urgent.
Integration model
API-friendly
Publish readings/commands via MQTT or simple REST endpoints.

Design choices

why this works well

  • Local-first control

    ESP32 logic continues working even if the internet is down.

    resilience

  • Cloud optional

    Use HA/MQTT for dashboards and rules, but keep critical paths local.

    integrations

  • Sensor isolation

    Tank monitoring is its own node; swap sensors without breaking the UI/alerts.

    modularity

Where the real integration goes

swap simulation → MQTT/HTTP

  • Lighting

    In Toggle(), publish an MQTT message or call your REST API to trigger a LightwaveRF scene/device action.

  • Tank

    Replace the simulation methods with values coming from MQTT telemetry (or polling an endpoint), then render percent/liters + alert thresholds.

  • Auth & safety

    Gate write actions behind auth, and keep a “manual still works” mindset for lights.
