Sinope water valve shutoff

[fdelima]

I have a Sinope Water Valve VA4220ZB. I have the Sinope Water flow meter attached to it too.. All is fine and Hubitat controls it perfectly.
The issue im having is that regularly at 8am, almost daily, the water valve closes. Its not closed by a rule or webcore piston. At that time there is water being used in the home.

Could it be possible that there is a internal shutoff rule/threshold parameter, in the valve or flow meter depending on the duration and amount of flow ? This is only my wild guess as I dont see any documentation from Sinope supporting my hypothesis.

Has anyone else experienced this ?

Yes, have a look through this topic (including a temporary solution):

Sinope VA4220ZB Gen2 with FS4220 problem

I bought the VA4220ZB Gen2 with FS4220 so I could remotely check in on water flow and remotely close the water main when necessary. This all works pretty well until my water softener cycles and the valve automatically closes. Before purchasing, my research implied this automatic leak detection functionality could be turned off - and it looks like it's possible with their hub and Neviweb app, just not with the built-in Hubitat driver. Poking through other third party integrations online it look…

Thank you for this reminder. I also experienced some anomalies in the past month or two that resulted in nuisance valve closures.

In my case, the flow value stopped updating. Not sure what the baked-in flow vs time thresholds are, but we hit them. In a webCoRE piston, I now log each time that the value fails to update for 45 minutes (and also does a refresh command). It last happened 17 days ago, so maybe it was a transient glitch?

I have separate rules for flow vs time, which have never tripped. The baked-in limits are more aggressive.

thank you very much for this. This is precisely my issue.... i timed my situation today and it took EXACTLY 3600 seconds ( 1hr) of water flowing (pool filling up) for the Sinope Valve to automatically close.. Ive written a Piston that opens the valve, if the pool hasn't finished filling and the valve closes.. Ideally changing the internal thresholds is the proper solution.

thanks again !!

thanks for the response.. so is the valve a little unstable from Sinope ?

@Hatallica

the flow value stopped updating

What is your water source? The only issue I've ever seen with the flow sensing device itself is when the turbine gets stuck (e.g. sand from the well when water level gets low). Usually a little backflow gets it going again.

Otherwise one thing I don't like about the built-in driver is that when actual water flow stops, the driver's flow attribute value stops updating without going back to 0. The attribute only gets updated to 0 when flow starts again.

The valve is incredibly well built and robust. The flow sensor is a plastic turbine spinning inside a metal cavity. A hall effect device records rotations. In my experience of over two years using this valve / flow sensor combination (and tens of thousands of gallons) with the exception of the aforementioned (rare) issue it has been very reliable.

I wouldn't go so far as to say "unstable". Communication had a transient blip. Like most things, when I started watching it more closely, it went away.

There have been a few over-protective situations, meaning that it auto-closed before my own rules would have triggered. Once I change that setting, I will be happy for now.

Municipal tap. Our install is perhaps a bit "noisy" - vertical and too close to the 90-degree bend - so there is almost always some dithering of the flow value. We have some major plumbing work coming up, so I intend to reposition it in the middle of a horizontal run.
