This is what I use and it's quite impressive.

I've had it for a few years and it never has failed to run on time every time. Can automate more than lights with it and it's really just a point/click set and forget type of thing. My setup for my lights. :)

In fact there is the option. What I do is: I set two triggers, for example, tine to turn on the lights and time to turn the off. There is an option called name ID or soemthing like that and I set a name for each trigger.

When you then set the actions, in the advanced actions there is an action called "choose" if you select this action, on the conditions you can choose your trigger base din the ID name and the action you want to perform once the trigger is activated.

Before you start consolidating, consider what might happen if the switch is in an unexpected state. For example, someone turned off the heater or pump and you were expecting it to be on.

In other words, you need to consider what a "safe state" is for each thing and how your code, when it fails, reverts to that state. This is an example of "failsafe".

Note that I said "when it fails". This is true for all software, even on mission critical systems.

Source: I write software for a living.

It's possible but honestly it's a bit off-putting to me.
For scheduled actions I use the Scheduler addon: It's mostly for covers and awnings, I don't schedule lights on and off, I enable their motion sensors depending on the time of day, but that's a more complex automation and I wrote it in Node-RED, which to me is a cleaner approach than the automation system in HA.

The Scheduler has the advantage of being wife-accessible too!

I use scenes and automate those scenes. That way, if I ever get a new light or have to replace a bulb, I only have to update the scenes.

Don't even think about bipartisanship.
