you can charge but its a primitive way of doing it at present and so its not a smart as others. It’s a shame as ive looked Into it as we have solar and battery storage. I am considering that if Ohme can’t do it in the longer term, getting a solar charger the same brand as my setup at home so that in the summer, I will plug into that and when octopus ofer good rates or in winter, use the smart charge on Ohme.
