Illustration 1: EmonEVSE WiFi Setup
•OpenEVSE should now connect to local WiFi network
•Re-connect device to local WiFi network and connect to OpenEVSE
using http //openevse.local, http //openevse or local IP address displayed on LCD on first
connection and each time on startup.
If WiFi connection / re-connection fails (e.g. network cannot be found or password is incorrect) the
OpenEV E will automatically revert back to WiFi access point (AP) mode after a short while to allow a
new network to be re-configured if required. Re-connection to existing network will be attempted every
5 minutes.
For a full EVSE web interface setup guide e.g Emoncms. MQTT, SolarPV divert see
https://guide.openenergymonitor.org/integrations/evse-setup/
For technical details of the WiFi gateway e.g remote open API control see

GFCI Self Test Failed EmonEVSE did not detect a GFCI Fault
during test Check GFCI CT and Self test coil
Earth Ground Test
Failed EmonEVSE could not detect a Ground Check Ground Connections and

Stuck Relay Test
Failed
EmonEVSE read AC voltage before
Relays were closed Check Relay and AC_Test Lines
Session Errors
GFCI FAULT EmonEVSE detected a ground leakage
of > 20ma
EmonEVSE will rerun GFCI self-test

indicates immediate failure. Charging
is suspended. If GFCI continues
regularly Contact Support
NO GROUND EmonEVSE lost connection to ground Check Electrical Ground, Contact
Support
STUCK RELAY Power was detected when line should
be open. Contact Support
VENT REQUIRED EmonEVSE read a pilot signal at 3V Ventilation requested by the Electric
Vehicle.
DIODE CHECK EmonEVSE did not detect a Vehicle Ensure Charge handle is dry and
clean. Contact Support.
HIGH TEMP
High temperature event (over 62C),
detected during last charging session
temperature throttling was engaged.
Investigate cause of high temperature
event. Charge at lower current, keep
unit out of direct sunlight and check
internal wiring.
OVER TEMPERATURE Temperature over 72C detected
If outside air temperature is very hot,
keep station out of direct sunlight and
charge at lower current. Check
internal wiring and contact Support.
