I recently got an Emporia EVSE. I've always wanted an OpenEVSE for the control flexibility to integrate with home excess solar, but the power company rebates would only cover a couple of really expensive home EVSEs that they could manipulate (Chargepoint and something else).
Recently the power company opened their rebates to most any EVSE that's Energy Star rated and the Emporia was on their list, awesome, $500 rebate more than covers the Emporia, and the Vue power monitoring system is reasonably priced. It can be wired for up to 48A charging (60A breaker).
With the Vue power monitor, they have an excess solar function to control the EVSE. And, there's an open source package to control it, PyEmVue which piggybacks on Emporia's cloud, but at least it works and I can hook it into my other home automation & solar controls.
So, one minor issue so far. When I turn off the EVSE remotely (from the phone app, or with PyEmVue), the EVSE beeps and comes up with an error, during the time that the Leaf is waiting with contactors still closed, in case power comes back. When the Leaf gives up after about 5 minutes, then the beeping stops and the error goes away.
It says: Abnormal control pilot circuit. Unplug and plug-in Emporia EV Charger.
Has anyone seen this with your Leaf and an Emporia EVSE? Emporia support is looking at it, I think it must be the EVSE. Thanks!
