Thank you very mutch, going to use it!

seamus65 · December 16, 2020, 5:19pm

Let me know if there are any problems.

The automation works for me, but converting to blueprint might have done something.

123 · December 16, 2020, 5:43pm

Why does the blueprint request inputs for charged_percent and low_percent but only uses them in the automation’s condition and not its trigger? In the trigger, the values are hard-coded to 80 and 30. Shouldn’t the triggers also be using the inputs?

seamus65 · December 16, 2020, 5:43pm

Oops, I will fix that…

seamus65 · December 16, 2020, 5:45pm

That should be it fixed now.

Good spot, a leftover from testing and converting from my automation.

Has anyone successfully imported this?

If I use the github url I get:

mapping values are not allowed here in “”, line 16, column 77: … charger will turn off. (default: 80%) ^

If I use the community thread url I get:

No valid blueprint found in the topic. Blueprint syntax blocks need to be marked as YAML or no syntax.

digidude · December 18, 2020, 10:31pm

i also get an error when trying to import this

seamus65 · December 18, 2020, 11:14pm

I think I have fixed it.

Let me know if it works now.

mike · December 18, 2020, 11:17pm

Thanks muchly!

jonasgustavsson · January 22, 2021, 5:54pm

Thanks! I had plans for creating exactly this automation.
Since my switches are Philips Hue light switches, I had to find/replace all ‘switch’ with ‘light’ in the Blueprint.

seamus65 · January 23, 2021, 6:23am

That’s good, glad it works for you.

malesci · March 2, 2021, 3:44pm

thank you very useful, I’m using it for a smartphone that is always connected to the electricity grid. As a further improvement it would be very nice to be able to introduce a logic to prioritize charging during the night when electricity is cheaper. Do you have any plans to produce something like this?
thank you

seamus65 · March 3, 2021, 6:00am

Thank you.

I do not have any plans to modify this at the moment, but the blueprint files are reasonably easy to modify, you could make a copy and have a go at modifying and updating yourself and let me know how you get on.

thanks for this

xbmcnut · October 14, 2021, 1:07am

Just what I needed, thank you! My attempt was an epic fail so I was pleased to stumble across yours which addresses my Home Assistant start-up issue.

Hi, I am new to HA, have tried to use your blueprint, to control power charging to my wall tablet running HA but can’t seem to get it to works - What am I doing wrong - any help would be appreciated

use_blueprint:
path: seamus65/wallpanel-battery-management.yaml
input:
battery: sensor.galaxy_tab_a7_battery_level
charger: switch.latched_hidden_switch_single_switch_1

seamus65 · December 14, 2021, 8:47am

Hello,

Are you seeing the battery percentage in home assistant from sensor.galaxy_tab_a7_battery_level?

Can you manually control switch.latched_hidden_switch_single_switch_1 from home assistant and does it control the charge of the tablet?

116port · December 14, 2021, 11:22pm

Thanks for responding

Yes, and I can switch the unit on and off, just not via the automation

116port · December 14, 2021, 11:24pm

Also forgot to Mention that I’m using for fully kiosk on the tablet
