When setting up the Equalizer there are a few things to keep in mind:
Make sure that you are using a supported smart meter with a HAN or P1 port.
Verify that your HAN/P1 port has been opened by your grid operator.
Unplug and plug back in your Equalizer.
The Equalizer may use up to 30 seconds to power up after being connected to the meter.
