[BUG] Reports a negative entity in an individual device as positive

[TransientWolf]

**Describe the bug** I track the current import cost as an individual device reporting an entity that calculates to cost based on usage and tariff. I am on Octopus AGILE tariff so I sometimes have negative rates and for a period of time negative import cost. The underlying entity correctly reports the negative number. The power flow card individual circle reports the correct number but without the negative ('-') sign.

To Reproduce
Steps to reproduce the behavior:

1. Set up an individual device that tracks a sensor that can report a negative value
2. Check the power flow card when it should be negative. It is positive.

Expected behavior
I would like the number reported as negative

Screenshots
Attached showing the entity and the card.

• [ X I understand that this is a channel for reporting bugs, not a support forum (If you need help configuring the card, go to: Discussions).

• I have the latest version of the card installed.

• I have cleared my browser cache after installing, updating and configuring the card.

• The issue is not related to the UI-Editor not being rendered: "s.entries is not a function". This is a known bug, and is caused by Card Mod. Check the warning this readme section for more information on how to fix it.

Seeing a similar issue with a secondary battery that I've added as an individual device. Regardless of whether the battery is charging or discharging, it shows the same direction:

The I/O alpha value on the right is the raw sensor value, and the purple device labelled alpha is the corresponding representation. It has been set to "Invert Animation".

So the bidirectional feature was added before v0.2.0 and it looks like the issue was introduced during the refactor?

The InvidualObject has a property called isStateNegative defined at

power-flow-card-plus/src/states/raw/individual/getIndividualObject.ts

Line 75 in 0852c79

const isStateNegative = state && state < 0;

This is set based on the value retrieved by getIndividualState() at

power-flow-card-plus/src/states/raw/individual/getIndividualObject.ts

Line 71 in 0852c79

const state = getIndividualState(hass, field);

But getIndividualState() returns the absolute value and so will never be negative

power-flow-card-plus/src/states/raw/individual/index.ts

Line 14 in 0852c79

return Math.abs(individualStateWatts);

That's the cause, but I'm not sure if it's safe to simply return the original value since it may have an unintended consequence elsewhere if that value is negative.

Hi any news on this?

[mypi-home]

bump...

[mypi-home]

Shall we just submit a PR to remove the absolute part?

@parnham have you investigated any further?

I encountered this bug too. Would love it if it was fixed.

OK I made a PR to potentially fix this issue and provide option to allow negative values on individual devices just like secondary:

#829

I have tested this on my setup and it works - see negative on charging Powerwall battery which is individual entity as its my 2nd battery:

It took some figuring out but here is how you can test this change yourself:

Download the attached zip file and extract the .js file.

power-flow-card-plus.zip

Place the file in your Home Assistant config folder at:
/config/www/power-flow-card-plus.js

Uninstall the original HACS version

Goto Settings → Dashboards → Resources → Add Resource

URL: /local/power-flow-card-plus.js?v=devtest1
Type: JavaScript Module

Do a hard refresh in your browser (Shift + F5). Check the browser console for errors.

If it worked then you should see a new UI toggle for "Accept negatives" on your individual entities.

If it works for you comment on the PR that its tested.

If anyone knows a better way to test from a PR directly let me know as I had to build the js file offline to test.

Enjoy!
