Powercut, TIC not stored in utility meter / stats

1

Last evening / night we had a powercut.
My TIC, providing information from the electricity meter to HA (via Z2M) is on zigbee and the current power (in VA) continues to be registered, as expected.
The TIC also provides increasing totals which I then use in a utility meter to track daily usage

The total increasing shows this

The utility meter based on that sensor shows ‘empty’ during the hours of the powercut

Is a powercut preventing the utility meter to function?

What is a TIC?

Sorry…local talk… the tic is a device that sends data from the electricity meter to Z2M, in my case it sends a.o. the current power (in VA) but also the total/increasing energy (in kWh)
I received all these values during the powercut, just the utility meter seemed to not have written anything to the database…which is odd, or?

This is the combined energy growth on which the utility meter is based, anything with linky_ comes straight from Z2M…and all is entering in HA, see graph above

      - name: "Linky Energy HPHC"
        unique_id: Linky Energy HPHC
        device_class: energy
        unit_of_measurement: kWh
        state_class: total_increasing
        state: "{{ states('sensor.linky_bbrhcjb')|float(0) + states('sensor.linky_bbrhpjb')|float(0) + states('sensor.linky_bbrhcjw')|float(0) + states('sensor.linky_bbrhpjw')|float(0) + states('sensor.linky_bbrhcjr')|float(0) + states('sensor.linky_bbrhpjr')|float(0) }}"
        availability: "{{ has_value('sensor.linky_bbrhcjb') and has_value('sensor.linky_bbrhpjb') and has_value('sensor.linky_bbrhcjw') and has_value('sensor.linky_bbrhpjw') and has_value('sensor.linky_bbrhcjr') and has_value('sensor.linky_bbrhpjr') }}"

this is the utility meter
