Hello all,
I’m searching for an easy-fitting, non-invasive Lora water meter. I’ve seen a few horror stories on the forum about the Nordic one so wanted to double check if anyone had any experience of the Quantify clamp-on https://quandify.com/cubicmeter.
Also open to anyone’s experience of OCRs

Bumping up 
I’ve just started using the Quandify water grip, based on the same technology. First impressions are good. It seems accurate (within 10% by measured volume, probably better). It’s responsive to changes in flow when in live view mode (via Bluetooth). My main reservation so far is that the sample rate for reporting is 60 minutes, and the alerting is taking some tweaking - the alerting through the app / portal is basic - exceeding a flow rate over a number of seconds - running a bath for the children generates an alert (until I’ve worked out the correct parameters).
These are inevitable quirks, but you should check you are happy with the sample frequency.
I’ve not yet connected to the api to extract and store data / apply my own logic.
