I was recently made aware of this ultrasonic sensor that measures water consumption (flow). It has MQTT support and integrates with Home Assistant, providing a couple different approaches to bring it into Hubitat.
Was wondering if anyone has tried it out ....
Installed it a month or two ago.
It detects all kinds of vibrations (I guess) as water flow.
The Flume that’s monitoring my water meter (only a few feet away from Droplet) is much more acccurate.
I wish Flume had a local interface to integrate with.
Ugh. Entirely defeating the purpose of using it. Can the sensor be calibrated by the end user?
Thanks for reminding me! I completely forgot that I had a Node-RED flow that grabbed daily data from Flume (via cloud APIs) and stuck it into a database. I have been receiving random alerts about a potential "leak" and I had basically ignored it thinking that it was a false alarm.
Well - I matched up the previous water bill and it was almost bang on 
. Now to go hunting for the leak next time I get an alert.
For anyone else -
The Home Assistant community has an ongoing discussion on the Hydrific Droplet. At least one person has reported the same issue described by @marktheknife
Not yet. We did mention it in this thread. I would not use one alone. I think they could be fun for a data nerd.
I’m sure there are ways I could try to optimize its placement or it could try to optimize itself further.
But I just don’t see the current state, which is unusable, getting to a point of even half way decent for me. Or even if possible, probably too much effort to bother.
Yeah as far as I’ve noticed, flume is very good at detecting whatever it is that’s spinning inside the water meter, and nothing else. So it’s always spot on for me as well.
In case you haven't looked already.
Thanks, sometimes I have a pretty good idea what vibrations it’s registering as water flow.
For example, one of my kids has bass practice downstairs in the basement right now (right next to the mechanical room).
So I could try adjusting it’s placement a bit, or reinforcing the exposed pipe it’s on, but I’m just skeptical whether the juice is worth the squeeze in the end.
Yea, that sounds like it would impact all things and everyone.
LOL
That must be what I've been hearing all the way out here in SoCal...
Are there Hubitat drivers or an app to connect (over WiFi, I assume) with the Hydrific Droplet? I searched a bit on those names and came up with nothing.
It has a home assistant integration.
Or if you use mqtt I believe it could integrate with Hubitat that way.
Thanks, I had assumed from your previous post you were using it with some standard Hubitat drivers.
It would be great if current Hubitats could host an mqtt server natively. (I gather Home Assistant can host one.) It 's kind of a pain to spin one up in a Docker container just to try out a new sensor.
HA code here is you want to have Ai generate a Hubitat app/driver.
