How can I take pictures at preset times throughout a day?

I need to take a close up picture of an object at up to 8 different, pre-programmed times a day (i.e. 6:00am, 7:00am, 7:30am, 12:00pm, 2:30pm, 6:00pm, 7:00pm, 8:00pm).

I have looked at trail cameras but they seem to be mostly motion triggered.
Intervalometers seem to be only programmable at time intervals like every so many hours.

I will have Wifi access at the camera location and would like to minimize costs.
