I’m looking at the EnomEVSE, as will attempt to get one installed before the OLEV grant ends. I’m wondering, is it ok to leave a cable permantly plugged in and treat it as if it were tethered? Does the cable click in to the socket so it is locked in?
From a technical point of view you can leave the cable in all the time, and I certainly do that with no problems. There is however no way of locking the cable in. There are a few related tickets, https://github.com/OpenEVSE/ESP32_WiFi_V4.x/issues/289 and https://github.com/OpenEVSE/ESP32_WiFi_V4.x/issues/189 and I think there may be some hardware changes needed as well.
