Help please - trying to calculate a number for number.set_value

[NewbyD (Dave)]

Hi.
I’m trying (and failing) to set a battery discharge rate, so I can discharge my giv battery in the evening, before charging it again overnight.
In an Automation, I have a working trigger and condition, but can’t figure out how to get maths into the action, to calculate the required discharge rate. The idea is that at 9:00pm, I check the SoC, work out a suitable discharge rate so it’s down to 20% at 11:30pm, then switch to charging again.

What I have so far:

action: number.set_value
target:
  device_id: 9117e75e28fdd3274821c26a73c4dd0c
  entity_id: number.givtcp_cexxxxxxxx_battery_discharge_rate
data: 
  {% set DischargeRate = states('sensor.givtcp_cexxxxxxxx_soc') * 3000 | float %}  
  {{DischargeRate }}


I've had many error messages as I've played with quotes and alternative structures. The error message for this try is:
Action YAML contains syntax errors, please fix the syntax

Any help much appreciated.
thanks, Dave

Please format your configuration properly so we can tell what is wrong.

How to format your code in forum posts

Spaces at the beginning of the line are critical in yaml, and people trying to help you may want to copy your code so that they can try it out themselves, so please format it correctly when you are posting. Use the preformatted text tool (</> in the edit post toolbar). If it is not immediately visible, it will be in the cogwheel menu. [Code_format] Alternatively you can use three backticks (the key is on the far left, 2nd row on en keyboards) on their own line above and below the code. That i…

Compare what you have to this:

action: number.set_value
target:
  entity_id: number.givtcp_cexxxxxxxx_battery_discharge_rate
data:
  value: "{{ states('sensor.givtcp_cexxxxxxxx_soc') | float(0) * 3000 }}"

Question for you:
Your example specifies an entity_id and a device_id. Are you trying to set the value of two number entities?

EDIT

Correction. Forgot to include the value option.

Done!
Thank you for the guidance on how to do it.

" Your example specifies an entity_id and a device_id. Are you trying to set the value of two number entities?"
No. I used the graphical editor to provide an example of what’s needed, and it came up with the 2 entries. Then tried to edit it in yaml, and have been fixated on the maths ever since. Staying with just the entity seems logical.

I’ve tried the example you provided (with the value line), and it worked - thank you so much!
