Programming Light Switch

Just wondering if anyone is working on an update to the light switch program. Seems as if you can only create one "on time"
I have an attic gable fan that i am trying to cycle for 5 minutes every 30 minutes in winter when my ridge vent blocks w snow. It would be nice to be able to have the switch come on on a schedule (such as hourly) currently you can select “turn off after a period of time” but there is no “turn on after a period of time”

You might find that this fits the bill…although I have not used it in the manner you describe, it does have timed on/off capabilities…
