Your Phreno sensor has a built-in LED indicator that gives you a quick visual status during charging. Here's how to read it.
💡 What the LED Colours Mean
LED State | What It Means |
🔵 Pulsing Blue | Sensor is currently charging |
🔵 Solid Blue | Sensor is fully charged |
That's all you need to know for now! The LED is currently used for charging feedback only.
🙈 Why Can't I See the LED During Normal Use?
At this stage, the LED sits inside the sensor housing and isn't visible once the sensor is fully assembled. This is intentional — it's currently used for internal debugging purposes during the charging process, so you'll only catch a glimpse of it while plugged in.
🚀 What's Coming
We're working on expanding the LED's functionality in a future update — think real-time status indicators, impact alerts, and more. We'll keep you posted as these features roll out!
