I’m looking (without luck) for a device like the Drop or Flume that can meausre water flow through a pipe. Those devices are not available in Australia, and my water meter is 60m down the driveway at the street, so can’t use a pulse counter as it is too far from my house.
Any suggestions?
You could insert a pulse meter into the pipe next to your house? (or let someone else do it.)
Check out Moen Flo. Needs WiFi though so that may be limiting for you.
Thanks , but alas, like most of these devices, it is not available in Australia. 
Do you mean something like this?
I have used in Australia, integrated with Home Assistant, but did not do the purchase so not sure of the answer.
Hi folks
Any other suggestions?
I already have a Zigbee controlled switch on the main water pipe next to the house, so can turn it off if I detect leaks inside the house. However, still looking for a way to measure flow through that pipe.
Happy to have it installed by a plumber, but it needs to be available in Australia. Any suggestions welcome.
Did you find anything in Australia?
Alas, no. And for the moment, have given up trying!
You can use one of these at your house’s water pipe entry point. The only issue is that you need to automate to keep it open all the time as they have a built in timer to shut off… or pull it apart and force it open.
Im so sorry this is off topic but were you able to get the wx8 in the Holman app aswell as the tuya smart app?
If you really want an overseas one you could probably just use a port forwarding company to send it to you from overseas. Might just need to sort of the electrical supply if it’s designed for 110v and can’t take a wide input voltage, which is getting more rare these days.
Another option would be to buy a flow sensor and pair it with a microcontroller like an esp32. That could give you flows into home assistant if that’s all you’re after.
There is also an Australian made product called Aquatrip that is designed to monitor flows and turn off the water if it flows over a preset time. It’s standalone though and doesn’t use wifi.
Another useful tool would be the Hydrific Droplet clamp-on ultrasonic water meter.
Sadly they not only don’t support overseas sales, they block access to their app and API from outside US!
I contacted them and they said “we are actively exploring opportunities for international expansion”
Hi David - did you ever find a water flow meter in Australia? I’m also on the hunt. I notice that Amazon will ship a Flume 2 to Australia. Am also looking on AliExpress but would prefer a device like the Flume 2
Cheers
Wow, just had a look at this Flume water meter. I am wondering how this can work by just strapping it around the water meter with a rubber band?
Does anybody have this installed?
The water meters have a rotating disk with a magnetic segment on them. The Flume device detects the magnet passing by on each rotation.
I since came to the conclusion that all those devices (Droplet, Flume and DN20) are a bit of overkill and complicated since I found out that my water meter has a pulse output port.
Basically I can purchase a pulse sensor (a reed contact) for about $100, take the rubber lid of the pulse port at the meter and screw the sensor in. It comes with a 5m cable which I can run into my property and connect to a ESPHome device or Shelly which counts the pulses. One pulse = 5l.
The water I have is the Elster V100 water meter which is a very common water meter in Australia. The matching probe to install is the Elster T110 probe, part number MEB7454.
you can buy one for closer to AUD$8.50, even less without a plastic package. ie: Miniature Glass Reed Switch | Jaycar Australia
Don’t get ripped off!

Yeah you are right, the official one is pricy, but they also seal the hole properly so no dirt gets in and have the correct orientation. I saw cheaper prices for the official one but only a plumber gets those trade prices. Ordinary folk pay double. I did some more reading in other posts and a lot of people had trouble with the DIY sensors. Maybe I give the DIY solution a go first and see how I fare.
Where are the 3D print templates for the reed switch so it fits the water meter at precisely the correct spot to detect the passing magnet? The T110 pulse sensor comes with a dropping resistor and stainless steel screw as well if I recall.
