Charge battery automation

Configuration
1

I got this automation, which I thought will be easy, all I need to automate is when the voltage drops to a value turn the charger switch on.
I can see the voltage reading on “sensor.voltage reading” entity but its not operating the relay , am i missing anything here

id: ‘1695049958056’
alias: battery change below 12

trigger:

  • platform: numeric_state
    entity_id: sensor.voltage_reading

The obvious error is attribute: unit_of_measurement. That means you’re looking for 'V' to drop below 12.5.

Remove the attribute line. I suspect you were tricked by the UI into selecting something, but you want to compare the state of the sensor not any of its attributes.

There could be other errors lurking in there that we can’t see because of the formatting: see prior post.

Hi Troon, i think that helped and i re wrote the automation because , i can see in the log it was being triggered but it was not turning the light on
my realy config is this

switch:
  
  - platform: gpio
    name: "Battery-charge- Relay"
    pin: GPIO04
    id: relay
    
  - platform: template
    name: "Battery-charger-on"
    turn_on_action:
        - switch.turn_on: relay
        - delay: 7200s
        - switch.turn_off: relay

    turn_off_action:
      - then:
        - switch.turn_off: relay
        - switch.template.publish:
            id: relay
            state: OFF

i thought in my automation i will get an option to select “Battery-charger-on” or “Battery-charger-on” is valid
any thoughts

all working now , the relay entity was reloaded and everything started working
cheers
