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 - Recieve (Green) connects to transmit on the remote device. Pin 5 - Transmit (Yellow) connects to receive on the remote device.

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

    • Green to TX , Yellow to RX (TX on WiFi goes to RX on board, RX on WiFi goes to TX on board)

  • 4) Mount the WiFi unit by using an alcohol pad to clean the enclosure at the desired mount location. When dry remove the plastic on the high temp industrial double sided tape and 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

With a phone or laptop connect to http://data.openevse.com/emoncms/.
  • With a phone or laptop connect to http://data.openevse.com/emoncms/.

    • Navigate to Setup => Device Setup Click the Pencil icon to edit. Set Name, Description, Node (0-9), Type "OpenEVSE" and copy your Device Key.

  • Once device is setup connect to OpenEVSE WiFi to configure the WiFi Module:

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

    • Address: 192.168.4.1 Default Username: admin Password: openevse

    • Enter the SSID and Password of YOUR access point.

    • Enter the Device Key, Node (0-9) and set

    • Click Submit.

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.

  • Go back to OpenEVSE Energy Monitoring

    • Select Inputs - Navigate to Setup => Inputs. The Inputs section should now display live data from OpenEVSE.

    • Inputs from other sensors can be included such as additional current, temperature, humidity, voltage etc. See Open Energy Project

  • Inputs displays live data from the sensors. This data is not stored, logged or archived.

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.
