Been thinking about adding this to the card. Here is another way to calculate using a sensor template in HA for those who don't use Node Red
- platform: template sensors: soc_battery_time_left: friendly_name: "Battery Depletion Seconds" unit_of_measurement: Seconds value_template: "{{ ((((states('sensor.battery_soc') | float - 20) /100) * 15960) / ((states('sensor.load_power') | float + 60 ) | float) * 60 * 60 ) | timestamp_custom('%s', 0)}}" soc_battery_time_left_friendly: friendly_name: "Battery Depletion Time" value_template: > {% set time = states('sensor.soc_battery_time_left') | int %} {%- set minutes = ((time % 3600) // 60) %} {%- set minutes = '{} minutes'.format(minutes) if minutes > 0 else '' %} {%- set hours = ((time % 86400) // 3600) %} {%- set hours = '{} hours, '.format(hours) if hours > 0 else '' %} {%- set days = (time // 86400) %} {%- set days = '{} day, '.format(days) if days > 0 else '' %} {{ 'Less than 1 minute' if time < 60 else days + hours + minutes }} 15960 = Battery capacity in Wh (Update to match your battery size)
20 = Minimum SOC
Added 60W as per your logic to cater for inverter self power
Probably add it to my load shedding card
