One is implementation of multirelay mode, so I can switch between Single Phase and 3Phase charging. About this modification is on the network a lot of informations.

Regarding wake up of my Stellantis car, all is described here. It’s quite simple. Car will wake up when cable is disconnected and connected again. But how to do it remotely ? So I found, that enough is disconnect CP signal. Inside EVCS it is very easy. It’s this connector :
So I used shelly 1 wifi relay to do it.

Easy
