Home water pressure sensor



  • Anyone having a water pressure sensor either zigbee or Z-wave?

    I need to record and graph the water pressure coming in the house from the city...



  • One solution that I can think of is to use MySensors. https://www.mysensors.org/
    This is a DIY community platform for making sensors etc. It is supported by Vera and OpenLuup, @akbooer is using it if I am not wrong.

    I found someone that had made a water pressure sensor that you perhaps could have a look at for inspiration: https://forum.mysensors.org/topic/8731/water-pressure-sensor/1?_=1590472756396&lang=en-US

    In short with MySensors you set up a gateway and then the sensors you want. Each node is an Arduino or similar. I used an USB connected gateway with my Vera, but an Ethernet connected gateway is needed for OpenLuup.

    I set it up a number of years ago on my VeraLite and it actually worked really well. I used it mainly for simple temperature sensors. I stopped using it because of that each time the Vera rebooted the gateway was lost, and I had to re-discover it on the Vera USB port. Quite a bit of hazzle since the Vera had a tendency to reboot quite a lot.

    If I get some time I may have a go at restarting MySensors now that I am using OpenLuup since it would be a good way to add dirt-cheap sensors to the system.



  • AFAIK the only Zwave sensor is made by FortrezZ, now part of eZlo => https://www.fortrezz.com/flow-meter

    Ironically, not very well supported under Vera 🙂

    Zuno and a custom sensor is another ZWave route.



  • Maybe this helps... its not a working out of the box thing but...



  • Looks like flow-meter from FortrezZ is only reporting water consumption, not pressure!
    So my option is a DIY like @ArcherS proposed!

    Yes, I have used these. I even posted about openLuup on their site a while ago. My favourite system, for a while, was a mySensors gateway running on the Arduino on a Yûn board with its SBC running OpenWRT and openLuup. Worked a treat. Since then, their firmware has been updated, but so has their plugin.

    This, you have to blame on Vera’s poor luup.io module, which lacks the capability to restart a lost connection. Should be a fairly easy work-around to fix that on openLuup, which currently runs their gateway plugin with no modification, IIRC.

    Amen to this. On openLuup I actually made some small changes to the io module to restart a timed out connection. It is already in my fork.



  • @DesT so Zuno is probably your best choice, if you want to just enable zwave endpoints.

    Tasmota seems to be a cheap solution as well. It’s pretty easy to route MQTT messages to openluup/Vera via home assistant or the MQTT client plugin.
