Flow sensor from Pentair VSF

[trmb-vast]

💥 Proposal

What feature you'd like to see

for ORP and PH pump, I'd like to use a flow(rate) sensor already available from the pentair-VSF pump via vixie.

Motivation

I have a ORP pump already, Now that I'm adding a PH pump, it's now more important to dose only when the pump is flowing, but I don't want to add another sensor when I've got data from the VSF pump itself.

Pitch

Flow sensors are important for dosing pumps. but I want to use the flow data from my VSF pump. eg: "only dose when flow above 15 gpm".. existing feature seems to only support external REM switches and flow meters.

I have changes for REM to support 4-20ma flow rate sensors (generic device like a temp sensor), that I need to put in a Pull Request(PR) to get in the mainline. I wanted to add this to my nixie dash panel as well just haven't had a time to look at the changes needed for on the njsPC side. So, I second the ability to have flow rates there. Here is a screenshot of the REM side
