Looks like Watercare have installed me a nice new water meter and it looks like it has a pulse output which I should be able to connect this to....

Anyone done this to be able to get water usage showing up in their home automation system?

 

I've already done it with my power meter which has a light that "pulses" on the front. I have a sensor and ESP8266 that counts the pulses and converts this to energy usage. I then serve that up in my OpenHAB system.

Bit of a sideways answer, but I just got a known-to-work pulse-counting meter off ebay and used that rather than trying to connect up whatever Watercare may have installed. I'm using it with a Fluksometer, which also does power and, if I had it, gas.

Thanks, do you have a link or anything? If I were to add my own meter I'd probably add 2 so I can also track the amount of water going through the Rheem hot water gas heater.

It was some years ago and I can't remember the exact seller, I just found one on eBay from a seller in Germany and fitted it into the house water main, something like this.

Have you tried simply placing a reed switch on the side of the Watercare meter to see if you can get a pulse output that way?

That official reed switch that you linked to is mainly for use in remote reading systems. As it can be fixed in place with a tamper evident seal. As removing the reed switch in such systems allows people to steal water.

I'm assuming that you don't intend your home automation system to be used for say billing tenants for water use.
