Octopus Agile Tariff - Notify cheapest rate

Hi,

I’m still pretty new to Home Assistant but I’m getting to grips with it. I am on the Octopus Agile tariff and I’ve got the Octopus integration (BottleCapDave) as well as the Octopus Energy Rates Card (lozzd).

I have some automation setup to turn off my car charger if the rate is above a specific value but I would home assistant to notify me when the next day rates are available if the cheapest rate is below a configurable rate (say 5p).

I’ve spotted that the Octopus integration does seem to have a Next Day Rates entity, I just don’t know how to integrate this into an Automation for it to send me an alert if a rate is below a value.

Sorry, if this is a simple thing!

Thanks.
