Hey!

So I have had this template working for a while but recently noticed that I was getting negative values on my energy dashboard. After some research, it was suggested that best practice is to add an availability_template:. It appears the current template reports ‘0’ when the device is unavailable which explains the drops and negative values.

Source: Why an availability template is important for energy template sensors

Anyone know what to add to this template? Perhaps this could be of a starting point?

availability_template: "{{ not is_state('sensor.energy_monitor_instantaneous_demand', 'unknown') }}"

Original Template

template:
  - sensor:
    - name: "Live Electricity Usage"
      unique_id: "live_electricity_total"
      unit_of_measurement: "W"
      state: "{{ (states('sensor.energy_monitor_instantaneous_demand')|float * 1000 / 2000) | round(0) }}"
      state_class: measurement
      device_class: power
      #availability_template: "{{ not is_state('sensor.energy_monitor_instantaneous_demand', 'unknown') }}"

    - name: "Total Electricity Usage"
      unique_id: "total_electricity_usage"
      unit_of_measurement: "kWh"
      state: "{{ (states('sensor.energy_monitor_summation_delivered')|float * 1000 / 2000) | round(2) }}"
      state_class: total_increasing
      device_class: energy
