#Help with automations to automate battery charge at cheap power

Hi All,

So to make an educated purchase for a home battery next year, I am simulating various battery types and sizes via the battery_sim HACS integration.

However, on cloudy days, I want to boost the efficiency of the batteries by changing the battery mode to "Force charge" when;

  • *The current energyprice is at the lowest 10% of the day *AND the predicted solar power rest of the day is lower than 7

It needs to put the battery mode back to default if;
-- *The current energyprice is at higher than 10% of the day *OR the predicted solar power rest of the day is higher than 7

Now, I have tried in a few ways, but it never works, not returning to default mode, or changing to force charge if only 1 of the 2 requirements are met.

Question;
Any tips on how to use the AND and OR stattements correctly??

Just make a template helper that does the comparisons for you and merges cost low and generation low into a single entity and uses that, it's much simpler imo
That said you just want
If cost low and generation low - force charge
Else - default

#

You might also want to look at the predbat add on, been playing with it myself for the last few months and pretty happy with it

@stoic moon

Can I make A bnary sensor tmeplate with this as the state;

   and states('sensor.energy_production_today_remaining') | float(0) < 7 }}
