Help with pool pump automation - ca3750

I am new to smart things and really have no idea what Im doing. I have an intermatic ca3750 hooked up for my pool pump timer. I would like to how I can set it up to turn on at a specific time of the day (say 8am), run for a specific number of hours (say 4 hours) and then repeat it later on in the day.

Is there a smartapp out there that does something like this? I have no idea how to write one.

I would also like to have some type of an override on it for days where I need to run the pool pump for 24 hours because of chemicals added

Use smart lighting in lights and switches to turn it on at a set time and turn it off when power allowance exceeded.

The CA3750 has two switches that can be configured. I would like to automate each one. Any one have any idea on how I can do that?
For example I want m filter pump for to run for 5 hours and my vacuum pump for 2 hours. This allows the each feature to work properly without overworking/underworking the other one.

Randy, looks like we’re in the same boat. I asked the same question in a different thread. I’ll let you know if I figure this out and hopefully likewise. Thanks!

Check towards the bottom of the thread Intermatic CA3750 2xSPST control with SmartThings. I wrote handlers and a SmartApp that enables 2xSPST mode for this device. So far they are working well to control my pool, hot tub, and hot tub heater.
