Battery shows "battery charging" while it is discharging although I have used the *-1 "trick"

[Sobr87]

Hi,
I have used this line for the battery (copy - paste) from the example --> jq: .state|tonumber * -1 # this does the trick to invert the sensor value for evcc

But EVCC shows "Batterie laden" while discharging.

What is wrong in my code:

• name: bat
  type: custom
  power:
  source: http
  uri: http:// [my-HA-INSTANCE] :8123/api/states/sensor.battery_power
  method: GET
  headers:
  - Authorization: Bearer [my token]
  insecure: true
  jq: .state|tonumber * -1 # this does the trick to invert the sensor value for evcc
  timeout: 2s

I have also tried to delete the " * -1 " but nothing was changed, I believe there is no effect of the *-1 in this line IN MY CODE.
I have also restarted the HA after every change.
How can I make the *-1 work?

Thank you all in advance!

remove # this does the trick to invert the sensor value for evcc ?!

still not working :(
I have tried *-1 to an other sensor and it was working, it seems that *-1 has no effect only to the battery sensor

I am sorry - but then I am clueless - since this is IMHO a 100% evcc issue (and I only provided some example docu, how it worked for me in my repo)

Thank you for your support
Now sun is shining and its easier for me to understand the system, because all sensors are working now. I think everything in correct in your description. Now I have deleted the *-1 and it seems to work, I think my inverter provides already the correct value for evcc sothat *-1 is not needed.
Thank you so much for your work, now evcc seems to work also with my inverter, I am so happy that I have found your example!!!! :):):)
