YoLink FlowSmart NSF Certified Smart Water Meter - 0.75 Inch Smart Home Water Usage Monitor with Leak Detection, Includes Hub (YS1603+YS5007) - Perfect for Home Automation, Water Conservation, and Leak Prevention

I have a slow leak based on my increased water bill. So I installed this meter right outside my house. This has allowed me to determine that the leak is most likely past my shutoff, and unfortunately probably under my slab. (I can see that the leak is not in my yard between the water company meter and the side of the house).Positives: - Fairly easy to install. I had to dig out a hole to put it in, and also installed an in ground meter box. (note: I had a nice straight run of pipe to put it in, which is required to have accurate measurements) - No additional power wiring required on the outside of the house - The digital part that goes on the outside of the house uses standard AA size batteries (requires lithium AA batteries but comes with them). - The part that goes inside the house uses a standard USB plug and includes both WIFI and Ethernet port. I did initial setup with Ethernet and then was able to put the WIFI on my guest network (did not require local LAN access). Works fine with the Ethernet cord unplugged. - Both the Yolink hub and the outside digital part of the meter paired easily with the Yolink app (Android phone, app is in the play store). Paring is done by scanning a QR code, first on the Hub. And then later scanning the QR code on the back of the digital part of the meter. - Customer service responded very quickly to my feedback about the app.Negatives:- You only get a total water used amount and not a flow rate, where the water company meter gives GPM (you can select the units between Gal, L, CCF, M3).- My leak is too slow to be continuously monitored by the digital part. If I am not using water, my leak shows up as a periodic blip once an hour of about 5 gal. The meter is still measuring the amount, it just doesn't get reported on the app constantly. This is also kind of a feature because it helps preserve the battery life.- The wiring between the flow meter and the digital part that stays outside could be better. It comes with generic WAGO type connectors to connect between the digital part and the meter. There is no enclosure for this connector and it is left exposed. I kind of want to get an external box to put the digital part in now even though it is IP66 rated.- The app is not very intuitive. It does have quite a few features (it is designed to work with other yolink devices, but I only have the water meter). I was hoping to share the device with another user. I initially didn't see any option to do this in the app. So I submitted feedback that the functionality should be added. Yolink responded with instructions on how to set it up, since the feature was already there.
