Hi John we are sorry for the delayed response on the support side. We have a pretty large backlog we are working through. Can you take the cover off the station and send a picture? We can identify the relay for you.
Thank you and I understand. How about the other modules/firmware?
Here is a guide for relay contact cleaning.
If you would rather replace...
For other upgrades, we would suggest the new ESP32 WiFi with 4.x software. The ESP8266 is no longer supported and the 2.x software is quite old and no longer updated. The OpenEVSE controller should be updated to at least 7.1.3.
