I’ve been using the Energy Dashboard for over two years and already have a lot of historical data.
Currently, I’m using the Toon Smartmeter integration (configured via configuration.yaml).
Later this month, my electricity, gas, and water meters will be replaced with digital ones.
As a result, I won’t be able to use the Toon Smartmeter integration anymore and will switch to a Smartgateway P1 meter.
This means I’ll get entirely new entities, and the Toon Smartmeter integration will be removed.
However, this also means I will lose all my historical data from the Toon Smartmeter integration.
It should be possible to retain the data in the Energy Dashboard, even after removing the original entities.
