Note that if you have a TL-X inverter with multiple time slots, that it is important that the you don't have any other schedules enabled that overlap with the time windows you configure in Wonder Watt.
Wonder Watt will use time slot 3 to write to and will attempt to use this for export as well as charging.
The reason for this requirement is that if you have an existing schedule enabled which overlaps with the time window in Wonder Watt, we cannot set the inverter slot and enable it, as the inverter will reject it, due to the overlap.
