Nissan Leaf dashboard with charge limiter

I’m not sure about fun - you’ll see I used Templates for a couple of trivial tasks like offsetting the state_numeric comparisons, but it felt more like an exercise in batting my head against a wall because despite there being quite a bit of documentation it’s just vague enough in the right places that I had a hell of a time getting the syntax “right”, (or at least a working syntax) as a lot of the examples given in the forum here didn’t actually work…

Yeah, I found it to involve a LOT of experiments in the Developer Tools → Template page. It’s mainly the datetime object that gives me the most trouble.

@DBMandrake

Something seemingly simple like storing the SoC and last update datetime into variable storage for use by a future run of an automation is eluding me at the moment, and I’m sure I’d have to use a Template to do the actual calculation.

For storing values, use input_* helpers as they are called now. You’ll probably want to look at input_number.set_value service and use template in the data field.

@DBMandrake

can they be used in a mode where they’re only time and day of the week rather than calendar (numeric) dates ?
And where are you inputting the value for input_datetime.leaf_start_charge ? Do you have a widget in your UI for that so you can easily adjust it, like I have for my charge limit variable ?

Yes to both. See below for first, and use entities card for second
If you are not going for super sleek UI with pictures, entities card is your best friend.

input_datetime:
  leaf_start_charge:
    name: Leaf start charge
    has_date: false
    has_time: true
    icon: mdi:car-electric

@DBMandrake

Ideally I’d like to be able to specify zero, one or two timed climate control start times per day, for each day of the week, with the ability to click a check box or similar to turn off the ones I don’t need.

I also want to have a separate charge limit slider for each day of the week - easy enough create them in the UI but I then need some way to pick the correct one for the day in the triggers and conditions, I presume something based on your value_template above might be able to look up the day of the week then somehow select the correct input_numeric to use for that day ?

Check out schedule card? I’ve not used this myself, but might help with what you want to achieve.

Scheduler card/custom component

Scheduler integration for HA Introduction In my house I have quite some devices that I want to control based on the time and day. For a while I have been looking for an easy way to set up and manage the automations that control them. HA has lots of functionality, but some things (such as automations), are not as simple to use as I would like. So, I decided to create my own scheduler integration. With a mobile-friendly Lovelace card for managing it. What is the scheduler integra…

@DBMandrake

No need for that for me - the one built into the Nissan app works well for me.

There’s one built in to the app? I can’t find it… may be it’s not available for early CarWings.
Don’t worry about this, it’s off topic and HA method works well for me.
