I've just switched to Octopus Flux, as Agile prices have been so high lately, and set my battery to charge to 100% in the 02:00-05:00 3-hours cheaper charging window. However Wonder Watt seems to be setting the battery to charge at 48% one night and 43% last night, so the battery only reaches 83 or 81%.

I've set it to not use smart charging, and to reach 100%. Why isn't Wonder Watt setting the battery to charge up fully?

    adam You have probably set the 'Auto charge rate' toggle to on?

    You can either use the charge rate correction factor in the Advanced settings to increase our charge rate calculation to take that into account, or toggle the Auto charge rate to off, which will use full charge rate instead.
