Hi Folks!
(I can’t find any similar question or sensor modification in the past, so let me show my problem.)
I have a sonoff thermo sensor which controll an electric heater.
I see the daily usage with history:
- platform: history_stats
name: electric heater
entity_id: switch.sonoff
state: "on"
type: time
start: "{{ now().replace(hour=0, minute=0, second=0) }}"
end: "{{ now() }}"
The heater use a constant energy which is 1.1kW / hour
So i try multiply this with previous sensor
- platform: template
sensors:
electric_heater_kwh:
friendly_name: electric heater kWh
value_template: "{{ states('sensor.electric_heater') | float(0) * 1.1 }}"
unit_of_measurement: "kWh"
but it show me only 0
Maybe i have to modify the history sensor output for a natural number like 2,12 but i’ve lost with it.
Please if you have any idea write me.
Thank you
