Please refer to the tables below for troubleshooting purposes if there is any issue with your relevant device.
CX1 & CX1-SW
CX2-MB-SW
Note: For CX2 devices, Wi-Fi does not need to be connected for communication and is optional.
General Troubleshooting
Generally, if the meter is stuck on anything except solid lights, then power cycle the meter.
To power cycle CX1 & CX1-SW
Turn the connected breaker that's powering the meter(s) off, wait until all 3 lights have turned off and approximately 15 minutes before turning it back on.
No lights are on
If no lights are coming on, check if P1 in the voltage terminal block is receiving voltage. If it is receiving voltage, the meter is likely faulty. Contact support to run through additional troubleshooting methods and organise a warranty case.
Only L1 is on or flashing
If only the L1 light is solid or flashing, try power cycling the device. If the problem persists, then contact support.
L1 is solid, L2 is flashing continuously (searching for network)
If the meter has begun searching for a network and becomes stuck in this stage, check the cellular reception at the meter and try changing the orientation of the antenna. If it doesn't solve the issue, you may need to install an external or high gain antenna to improve reception. If the problem persists with good reception, try power cycling the device or contact support.
