Workflow
01Short press chooses a mute duration, long press starts the countdown, and the original NVR state is restored when the timer ends or is cancelled.
Overview
Gizmo Reolink Switch exists for a very practical problem: leaving home without creating useless Reolink alerts and recordings triggered by your own movement. Instead of opening apps and changing NVR settings manually, the device gives you a small dedicated quiet-exit workflow.
- One-button quiet-exit workflow built around an ESP32
- 16x2 I2C LCD and buzzer for fast local feedback
- Direct Reolink API control with automatic state restoration
How it works
The ESP32 handles the full interaction loop.
| Step | What happens |
|---|---|
| Choose | A short press cycles through the available quiet-exit durations. |
| Start | A long press confirms the choice and begins the countdown. |
| Mute | The firmware connects over WiFi and calls the Reolink API to disable the active monitoring state. |
| Restore | When the timer ends or is cancelled, the original NVR state is applied again automatically. |
The LCD stays focused on clear user-facing status, while the buzzer gives immediate feedback for selection, countdown, completion, and cancellation events.
Why it is useful
This project turns a repetitive home-security task into a dedicated physical control. It is the kind of build that feels small, but solves a real annoyance in everyday use.
- Reduce false notifications and useless recordings when leaving home.
- Replace a repetitive app-based workflow with one physical action.
- Use it as a practical template for small ESP32 home-automation controls.
