Saved copy
It looks like something changed on the Zonneplan end maybe. When the solar production is higher than the grid consumption, the consumption sensor goes to unknown. Which is fine when using the graph from the screenshots but impossible to use in other cards like mini graph card. Entity card also showing NaN at those moments. Concerns sensor sensor.zonneplan_p1_electricity_consumption Looks like it started March 12th.

Once Home Assistant’s HomeKit Bridge shares it, this device reaches Apple Home as a HomeKit accessory behind your Home Assistant bridge, so ReReHome shows and controls it like any other.
