Displaying Watts as Amps

Configuration
1

I’m using a ShellyEM with the stock firmware and have the device successfully added to Home Assistant but the device only provides the following values.

Is there a way that I can also have the Amps as well in Home Assistant? I would like this value to be updated so the recorder will be accurate as time changes.

In Home Assistant this is how the entities appear.

Use a template sensor.

Power / Voltage = Current.

Thanks for the pointer. This is what I came up with for my templates for my device names.

sensor:
  - platform: template
    sensors:
      current_channel_1:
        friendly_name: Shelly EM channel 1 Current
        unique_id: current_channel_1
        unit_of_measurement: "A"
        value_template: "{{ (states('sensor.shelly_em_channel_1_power') | float / states('sensor.shelly_em_channel_1_voltage') | float) | round(2)  }}"
      current_channel_2:
        unique_id: current_channel_2
        friendly_name: Shelly EM channel 2 Current
        unit_of_measurement: "A"
        value_template: "{{ (states('sensor.shelly_em_channel_2_power') | float / states('sensor.shelly_em_channel_2_voltage') | float) | round(2)  }}"

I don’t think “A” is the right unit of measurement but I’m currently working through docs. Also, under developer tools the template tab is a great help!

If the power is in Watts and the Voltage is in Volts then yes Amps is the correct unit.
