I've been successfully using the wonder watt automation to charge my battery for several weeks, but there now seems to be a problem. I've got it set to pick the cheapest Agile slots in two windows, one overnight and one prior to 1600. The overnight charging hasn't happened for two nights running, but the daytime has. I can see from the GE inverter logs that commands have been sent to charge and written successfully (example below), so it looks like wonder watt is doing its thing correctly. Why wouldn't the battery charge?
