Remaining charging time doesn't have a unit

[ChristianForstner]

I created a pop-up to quickly see some stats about my car.
You can see the state of charge (SoC), the car's range, and the remaining charging time. While the first two have units, the last one doesn't.

Opening the sensor details also shows that it doesn't have a unit:

I'm running version 1.6.4.

There is a unit, it's minutes by default. Have a look at the left, under "Verlauf". The unit is displayed there as min

[ChristianForstner]

Ok, but shouldn't the unit also be displayed for the current value like it's done e.g. for the car's range?

Car's range:

Remaining charging time:

Or is this maybe a bug (feature?) of Home Assistant itself?

[WebSpider]

I see what you mean.
In the definition of the two sensors there is one minor difference, that should only influence statistics. Ill tinker around a bit and see if syncing that makes any difference.

[WebSpider]

Nope, that does not make any difference. I'll dig deeper.

It turns out there are quite some bugs in the frontend when it comes to the DURATION type sensor (which this is as well).

[WebSpider]

As a workaround, you can add a template sensor to wrap around the sensor the integration gives you, or use an alternate frontend card. As soon as frontend solves this, we'll update this issue.

Make sure to make the template sensor of another sensorclass than DURATION, or the bug will remain.

The integration will not change the sensorclass itself, because it is in fact a duration, and this is used in the HA backend in multiple ways.

Thanks for the deep dive into the underlying reason. I think, I will just keep it as it is right now and wait until frontend solves this, since remembering the unit being min isn't that much of an effort.
