Hi,
I´m using a Shelly 3EM. With this I calculate how much energy is used on all 3 phases.
I also produce solar energy which i feed in balanced over the phases. E.g. 1000W is needed on phase 1, phase 1 supplies 300W, phase 2: 200W and phase 3: 500W.
I calculate the power consumption as follows:
#Strom Netzbetreiber gesamt
template:
- sensor:
- name: "Leistung gesamt Netz"
unique_id: leistung_netz_total
state: >-
{{ (states('sensor.shellyem3_channel_a_power')|float(0) +
states('sensor.shellyem3_channel_b_power')|float(0) +
states('sensor.shellyem3_channel_c_power')|float(0)) }}
unit_of_measurement: W
device_class: power
state_class: measurement
Now I also want to include the energy returned value (example: sensor.shellyem3_channel_a_energy_returned). However, not for the last 24 hours, but for today, the current month and the current year.
How can I do that?
