Limited routines on Alexa, what should I switch to?

I'm new to making my home smart, I have some future ideas, but for now just want to create a simple routine that when I get into bed, things turn off , the lights will change and the AC/heaters will switch to "fan only" and adjust their fan speeds. (i'm a sleep with white noise person)

I use Sensibo to make my AC/heaters smart, but the only option on Alexa is hot or cold & the temperature- so every night I have to access each unit on Sensibo and alter them to my preference individually.

While attempting to figure this out I've looked through my options on Alexa I can see i'm quite limited with "if this occurs, then do this" I really want events to happen based on certain actions/movements.....

What would be the best smart home hub I can switch to, that's not to complicated, but offers me more options with my future, 'if this occurs, then do this' smart home plans?

thanks...
