FAQ
FAQ
1. After installing the EM16, if the Refoss app cannot detect your device, follow these troubleshooting steps:
a) Ensure power supply to EM16:
- Confirm the EM16 has power by checking if the device LED blinks slowly in green (once every 0.5s). If not, press and hold the button for 5s to reset.
- Ensure the wire harness is securely connected and properly wired.
- Verify that the main circuit breaker is switched on.
- Ensure the breaker powering the EM16 is turned on.
b) Ensure Phone Connectivity:
- Make sure your phone is authorized for the Refoss app and has Bluetooth enabled.
- For Android users, activate Location Services to enable proper Bluetooth device scanning.
- iPhone users should ensure Bluetooth is allowed in Settings > Refoss app > Bluetooth Permissions.
c) Confirm EM16 Wi-Fi antenna installation:
- Check if the antenna is securely screwed into the energy monitor.
- Ensure the antenna is positioned outside the switchboard to avoid signal interference caused by the metal enclosure.
d) Attempt Power Cycling: Try power cycling the breaker connected to the EM16.
e) Restart Refoss App: Restart the Refoss app on your phone.
f) Reboot Phone: If issues persist, reboot your phone.
2. Why is the Refoss app unable to obtain real-time current and consumption data from the EM16?
- Ensure Proper Connection of Current Transformer: Check that the current transformer is securely plugged into the monitor. Loose connections can disrupt data transmission.
- Verify Load Device Status: Check that the cable with the transformer clipped to it is not connected to a load device that is not working. If the load device is not operational, it may not be drawing any current, resulting in no data being recorded.
