1) Connect the Red (+) lead of UBEC Power module to the +12v  header labeled RELAY 1/2 Common . Connect the Black (-) lead to the Ground Block. 2) Connect the power and data header (4 of 6 wires) to the Wifi Module. Pin 1 - Ground (Black)  Pin 3 - 5v (Red) - 75ma max (higher power devices must use external power.) Pin 4 - RX Receive (Green) connects to transmit on OpenEVSE Controller. Pin 5 -  TX Transmit (Yellow) connects to receive on OpenEVSE controller.

  • 3) Connect the data only header (2 of 6 wires) to the OpenEVSE Board.

    • From OpenEVSE Controller Green to TX , Yellow to RX

  • 4) Mount the WiFi unit to the desired mount location. Attach the WiFi module to the enclosure.

Trying to get the UBEC +V into the Relay 1/2 Common along with the wire to the Struthers & Dunn relay is a real trick.

I used the common on the contactor instead

Power on OpenEVSE WiFi to configure the WiFi Module. Using a laptop or phone connect OpenEVSE WiFi: SSID: OpenEVSE_XXXXXXX where X is a random digit --- Password: openevse
  • Power on OpenEVSE WiFi to configure the WiFi Module. Using a laptop or phone connect OpenEVSE WiFi:

    • SSID: OpenEVSE_XXXXXXX where X is a random digit --- Password: openevse

    • Address: 192.168.4.1 Default Username: admin Password: openevse

    • Select the SSID and enter the Password of YOUR WiFi network.

    • Click Connect

For initial setup, the board will boot in AP mode. The OpenEVSE_XXXXXX SSID is broadcast on 2.4GHz channel 1 with WPA2. If you have extremely strong interference on that channel, for example from an enterprise-grade WLAN, you may see the SSID and yet be unable to associate - even if you're right next to the EVSE. If that is the case, resolve the interference issue.

The OpenEVSE energy monitoring server supports powerful input processing and can send E-mails bases on flexible logic. Example 1 - Send E-mail when Charging is complete. Add the values in the red box to the OpenEVSE_AMP input. Logic: If the value is changing and now equals 0 then send an Email. If not Goto the end "99".

Step 2.2 has pins 4 and 5 reversed on the picture. I believe the description on the step on the right side is correct. The actual shipped connector has them in this sequence: BLACK, RED, GREEN, YELLOW. On your pic it's ...YELLOW, GREEN.

Can you connect to the device if you don't have a WiFi connection to the internet? I'm sitting at a park with my car charging and no WiFi signal except my OpenEVSE and can't seem to get any data from it.

Does the EVSE AP username and password need to be changed? Is the AP still accessable after I get the WiFi module connected to my home network? If the WiFi at my house goes down for some reason can someone connect to the openevse AP?
