Templating sensor in devices yaml config

[blakadder]

I'm working on adding support for a robot vacuum and trying to figure out how to convert the "time used" into "time remaining" sensor

Specifically I have dpid for vacuum consumables that are tracking their lifetime in seconds and this value is increasing.

Tuya app displays time remaining in hours which is a more practical way to display the time. The obvious way is a new template sensor in HA that would subtract the current value from the consumable lifetime but I'd like to replicate that in the device config to make configuration straightforward

[make-all]

There is an invert option if you know the range you want to invert over, it will reverse the number so max is mapped to min and vice-versa, it was required for lightbulbs IIRC when HA only supported mireds but most Tuya bulbs are in Kelvin.

Seems its not going to work

This error looks like it may be due to an incorrectly formatted mapping block. mapping always contains a list, even if there is only one default item. It should look something like this:

mapping:
  - invert: true
range:
  min: 0
  max: 90
