Adjusting the price point of charging

[DobbyNator94]

Describe Your Problem:
I don‘t fully understand how I change the price point, at when Tibber is charging the battery. I would thought, I give it a price like 0.12€ and then the plugin charges the battery as long as the price is about 0.12€.

Can someone give me a hint, what I have to set in the config?

Thank you!

Please update to latest version, i fixed the configuration panel. Set the value in euro e.g. 0.12 and time in minutes that will enable loading when reaching this price.
i myself use the loading time of 90 mins, after hat the battery is fully loaded. the solution cannot be more dynamic since the api call is allowed only once a day :(

if configured, you can see the activated tibber trigger also in the home app rendered image, see https://github.com/zerwuff/homebridge-alphaess?tab=readme-ov-file#image-rendering

please let me know if it works for you

Hey, thank you for your quick response:

updated the plugin.

I‘ve set it now to 0.15€. So below 0.15€ it begins to load the battery for 90 minutes, when my SOC is below 70%?

But why does he say here 0 cents? I would thought, that now are my 0.15€ are displayed?

Okay, after a reboot there are 0 cents. A few minutes later, this is showing:

But it says 0.30€? Where does that come from?
Maybe I ask stupid questions. Sorry for that.

Edit: I‘ve closed it by mistake..

my fault. i just looked into it. i gave you a wrong answer :( sorry, i had to look into the code first.
this value is actually the diff to the lowest price of the day in cents it will trigger the loading.
30 cents in your setting: load when price falls below 0.30 € -> all day now -> all green.

if set to 0.02 € & tibber lowest day : 0.2 €, reaching tibber of below or at least 0.22€ during the day will enable this trigger if the soc threshold is met.
this should draw your diagram now less green. give it some time to draw. it will refresh some minutes after restart.

i will fix the description of the setting tomorrow.

Difference is nice. But what about, when I only want to charge my battery, when the price is below 0.15/KWh?

Because I dont want to charge the battery, when all day long the price is at 0.35€ and at one hour the price ist at 0.27€. Thats the lowest point at that day. But I dont want to charge it for so much?

hi, updated v2.125.0 this includes a new value 'Tibber absolute threshold in euro' , that introduces a total max price that is acceptable to enable the loading. this wins over the difference value. please check if this works for you.

update (v2.126.0) should now also include this logic in the rendering of the daily tibber price image.

[DobbyNator94]

When i set „Tibber absolute threshold in euro“ and something stands in „Tibber difference threshold in euro“ for over the day charging, it doesn‘t display correctly on the camera picture for tibber loading. 0,23€ in absolute, 0,01€ in difference.

0,19€ in camera picture.

It‘s very unconsistent. I delete the value at „absolute“ it sets a 0,30 at the reboot. For me it doesn‘t work at the moment.

Hi, i separated each parameter for the description now. this should be more consistent now.
