At the moment, this may not be relevant, but as more and more electric cars are on the roads I can see how someone might just drive up to a private charger and start charging their car for free. Is there any security built in to ensure only the owner can charge from the EmonEVSE?
My charger has a key that must be turned to turn it on?
Yes. the EmonEVSE can be disabled via WiFi. Without access to your network and security credentials to login to the unit someone wouldn’t be able to start a charge.
