cannot import name 'INTEGRATION_METHOD'

See original GitHub issue

updated to todays nightly 2022.4.0.dev20220319 which has some DB updates and attributes changes and Powercalc fails to setup. There was a recorder DB going on also

so maybe that was interfering, but in the end this was raised:

Package package_powercalc setup failed. Component powercalc cannot import name 'INTEGRATION_METHOD' from 'homeassistant.components.integration.sensor' (/usr/src/homeassistant/homeassistant/components/integration/sensor.py) Platform error sensor.powercalc - cannot import name 'INTEGRATION_METHOD' from 'homeassistant.components.integration.sensor' (/usr/src/homeassistant/homeassistant/components/integration/sensor.py)

because of that it can not restart…

The system cannot restart because the configuration is not valid: Package package_powercalc setup failed. Component powercalc cannot import name 'INTEGRATION_METHOD' from 'homeassistant.components.integration.sensor' (/usr/src/homeassistant/homeassistant/components/integration/sensor.py) Platform error sensor.powercalc - cannot import name 'INTEGRATION_METHOD' from 'homeassistant.components.integration.sensor'
