Time Based Charging has been in enabled on my PW2 for 5 days now. It is part of a 4.5kW solar setup.
The amount of solar charge is highly variable at the moment, and the PW is doing a reasonable job at guessing enough charge overcharge to last until off peak kicks in the next night.
The app doesn’t have the clearest explanations as to the configuration options, and could do with the ability for you to opt for more or less conservative off-peak charge estimates.
Having off peak charging however makes the need for alerts in the app even more pressing. There’s a much higher probability of reaching 100% charge during the day, so it would be useful to be warned about this to enable you to use the excess.
For me, having a Samsung SmartThings device handler for the PW2 would enable me to do everything I want. Has anyone written one?
