Introducing the two LED States
The following two built-in features are designed to assist you with troubleshooting by indicating warnings or errors:
- The LED lights on the BrewBeacon hardware.
- The BrewBeacon Settings page for connection.
In normal operation, the BrewBeacon displays information about its current state with the following two status LEDs.
LED I
It provides information about the general system state and also displays three general device states:
- Operational and connected
- Setup required
- Error detected
| LED I | Description | Action required |
| ON | Operational and connected. | ❌ |
| Flashing very fast at boot | Boot sequence |
Wait for 2 seconds after turning on the device. 💡 If the device keeps flashing fast and never reaches a state of slowly flashing or steadily on LED1, this indicates an insufficient power supply. Power the device from a stable external USB power source. |
| Flashing slowly | Setup required | Finish setting up the BrewBeacon. |
| Flashing fast | ❗Error detected | Check the device wiring and installation. 📚 Explore further troubleshooting steps for your BrewBeacon. |
A continuously flickering LED1 indicates an insufficient or unstable power supply. If the device is being powered from the espresso machine, try supplying external USB power. If already using an external power supply, check it within the specs.
💡 On some espresso machines, all flow meters need to be connected to deliver sufficient power to the device.
LED II
Depending on the system state, LED II displays additional information.
Troubleshooting
Below is a helpful table to guide you through troubleshooting the most common issues.
| LED I | LED II | Description | Action required |
| ON (Operational) | OFF | Idle (Operational and Connected) | ❌ |
| ON (Operational) | n short flashes, then pause | Operational and Connected. Brew in progress on group n (if multiple groups are being brewed simultaneously, cycle through them). |
❌ |
| Flashing Slow - Connectivity | 1 short flash | No user data is available (factory state). | Connect your BrewBeacon to Cropster Cafe |
| Flashing Slow - Connectivity | 2 short flashes, then a pause. | Wifi credentials are available but no connection. | If the issue persists for 5 minutes after boot, check if your WiFi connection is available. |
| Flashing Slow - Connectivity | 3 short flashes, then a pause. | No internet connectivity. | If the issue persists for 5 minutes after boot, check the internet availability of your WiFi network. |
| Flashing Slow - Connectivity | 4 short flashes, then a pause. | No connection to Cropster Cafe. | If the issue persists for 5 minutes after boot, reboot the modem and the device. If the issue persists, perform a factory reset on the device and connect it to your Cropster Cafe account again. |
| Flashing Fast | n short flashes, then a pause | ❗Wiring error (Flow Meter activity on group n while EMC sees Solenoid activity on any other input group). | Check device wiring. Pay special attention to connection a brew group's Flow Meter/Solenoid to the same input. 💡 Leaks in the espresso machine can also lead to this behaviour. |
