[Feature request] Allow device to show custom values

[antropophob]

Thank you for component.
I want to ask to add some functionality. I haven't find any devices with low energy consumption, e-ink screen, battery power and open api to display some information in smart home scenarios. This Xiaomi device suits all this conditions and seems that it provides api (or not?) to display temperature/humidity from other sensors.
So I request feature to set temperature/humidity values on device screen via home assistant automations or scripts.
Thank you in advance!

As I know this device can display only data from integrated temp/humidity sensor
