Z-Wave Pulse counter transmitter for UK?

Hi all, does anyone know of a battery powered Z-Wave device what I can connect a pulse counter to and use it to measure how many pulses per hour, day, week, etc…

Basically, I want a device that will actively allow me to measure my water consumption on a real time basis, and I could not find anything for the UK market other than a device from Secure what is only compatible with a few water meters.

I did however find the “Elster Inductive Pulse Module for V200 & V210” what would fit my Elster V210 water meter that I have.

Thus does anyone know of such a battery powered device (Z-Wave or otherwise) what I could use with the above Elster Inductive Pulse Module and integrate into my SmartThings platform to measure my water usage.

Regards: Elliott.

I’d try Aeotec Z‑Wave Dry Contact Sensor. I don’t know the minimum pulse time it will read.

My process using this sensor, does lose about 1 ON or OFF event in 40-50 or so, in monitoring HVAC fan runtime. That loss could be anywhere in the reporting chain to me - in the sensor, in the wireless connection to hub, in the ST cloud handling, or in the IOT data collection service.

I don’t think there is a standard device type with built-in statistics ready to use for your purpose. In my case I would have the IOT service produce the statistics.

There are a few people that posted water meter installations, search for those. I haven’t gotten around to installing mine yet.

Thanks, but not sure how effective the battery life on that will be, being it will likley get a few hundred pulses a day. (A pulse for every liter of water used!)

I can endorse it as a contact sensor because I use 2 regularly for about a year. They are very sleepy devices that just wake for on/off events. I haven’t checked the voltage directly but the battery report is still 100% on both, and they report events every day.

HVAC and attic fan runtimes will have fewer cycles than a water meter but I have already planned to use this sensor for water meter - if the pulses are long enough then it will read. By hand, I could not make a pulse that failed to read.

Reading down to liter seems overspec’d anyway.

The below may be another solution, if only one would remake or update the official SmartThings Smappee smart app to incorporate the Smappee Gas & Water monitor.
