MELCLoud automation with Octopus Intelligent query

Hi,
I’m looking into an installation of a Mitsubishi heat pump & water cylinder with the wifi module for connecting with MELCLoud.
I just wanted to check before I purchase it for automation-wise, I know there’s the MELCloud Integration and I wanted to see how people have been getting on. I know the integration is somewhat limited, and i’m wondering if i’d be able to kick off an automation to turn on the heating & water heater during the times of my cheaper rates only, that dynamically change through the day. And be able to turn it off for any other time to only use the cheaper rate.

Cheers.
