Sorry for the off topic..
I asked this question yesterday in the Software thread. Lots of views, but no replies. Maybe someone here knows the answer, if there is one.
Is there an app, somewhat like a task scheduler, that can change the frequency on an S7/S9 depending on the time of day?
That would be great to increase the miner frequency after 8:00 PM and decrease it sometime mid morning when the heat returns.
Any answers or thoughts appreciated!

My R1 reboots every 48 hours to keep it alive... in that Antminer menu, it has scheduled tasks etc.
See those small ants run at
http://www.antrun.de/ .... 30 runners pointing to solo.ckpool.org.
Back to your question... some cron job to check time and perform those CLIs via SSH probably can do the trick.
I am sure we have many gurus here who are good in scripts..... kano and ck perhaps can give you expert guidance.
Personally, I would want all my miners to go full warp speed, after halving.It's too bad the new Ants don't have some kind of task scheduler built into the interface. That would be awesome.
I have programmed everything from COBOL and RPG to Visual Basic and Java over the years, but I have forgotten most of it and that kind of programming/coding is over my head nowadays.
Perhaps some of the coding gurus have or can come up with a viable option.

** Three more blocks today will make me happy!

EDIT: It's too hot here after 11:00 in the morning until around 8:00 at night to run full speed as I'm only cooling with fans now. It's 96F outside now.
