Sender Battery Low
The Sender and Clamp are usually located at the main electricity meter or the consumer unit at the property.
Replace 2x AA batteries at earliest opportunity. Do not use rechargeable batteries.
Lost Signal to Sender
The unit is no longer receiving messages from the sender unit. Possible causes:
- Batteries may be exhausted.
- Solar iBoost+ is positioned too far or too near to the sender.
- Sender unit pairing button may have been pressed inadvertently outside of the pairing process
