I don’t know how long my vacuum took when you display it as 2761s, just let me choose minutes or hours (or a mix) please!
It works with Temperature, so why not with time aswell?
(Yes, i’m aware i could create some kind of workaround, but why fix everything with workarounds when something similar is already built in?)
You should post and vote on the topic below. It’s what you are asking for but worded more generally to cover many types of conversions.
The position of the development team is that the sensor information from the device is passed to home assistant without modification. So if your vacuum reports in seconds, that’s what the integration will report.
