No, I still don't understand why including "433 ask" is inappropriate. And what you call word salad is an attempt to explain, in detail, what I am trying to accomplish. Someone may find it helpful. Not you, but someone.
And to tell you the truth, I don't agree with your summary of what I am trying to do. "There will be a need to figure out how the 0..1023 range of your origianl sensor can be met by scaling or shifting or otherwise the values coming from the flow sensor". This sentence makes little sense to me.
Three cliche's in 3 paragraphs.
I don't need to "try to get it working again", it never stopped working. It is working now as I type this. But it is reading a fixed value. My concern is, and has been, what will happen when the transmitter gets pulses instead of a fixed value. I don't have the new sensor yet.
I just wanted to discuss with someone how to handle this new input type.
