When I enter a schedule for all my other Kasa devices, the Kasa app shows (on the main page) the time (during the current day) that the next event occurs. With the HS107, this information does not appear. The schedule is enabled.
EDIT: Well, the reason that they weren't appearing, is because they weren't working. I tried entering a couple of new schedules, to no avail. Manual ON/OFF (device buttons & phone) worked fine.
So, I did a device reset to factory, re-entered the schedules, & now everything works.
Awaiting the sunrise/sunset offset firmware update. No rush.
