as we don't have a new capabilities message scheme yet, conditional
blocks are the way it works right now in the App.
The meanings of standard metrics and message data fields should not be
changed. Introducing custom metrics and a custom MP record is a possible
But having custom solutions for common things like this is a PITA. Maybe
we can work something out to convert the readings into the standard metrics?
For example: if you get a "health percentage", we could introduce a
configuration for the "100%" health pressure level, so we can get an
absolute value from that.
