I have an OpenEVSE that works well. I have been charging the EV at night on low tariff.
I have solar which up to now I have been using to charge a storage battery. However now that the days are longer and brighter I have surplus PV so am looking at the pv divert option.
As I understand it this can only be achieved using mqtt. Is this correct? The reason I ask is that for some reason my OpenEVSE will not stay connected to mqtt. The Wifi connection has been rock solid.
