Foxx Project Water Sensor on Amazon

[Araforn (Paul Barden)]

I’m using this particular application to detect if the salt in my water softener is low. It then reports back to ST.

I have designed a custom HMI for my house in codesys (PLC software) running on a raspberry pi. All the device data from SmartThings is used in my application based on the Open Dash API.

Raspberry Pi Codesys Project

Hi All. Its been just over a year since I’ve started this project and I’m finally at the stage where I have a fully working home HMI fully integrated with Smarthings and more. Huge thanks to pstuart and Open-Dash for providing the foundation on which I have built the project. Making an API work in a PLC environment was a challenge for me, interrogating a 25,000 + string for device data but its now working perfectly. Some Screens: Main Screen & Codesys Environment [MAIN%20Screen] Heating Screen [Heating] Diagnostics Screen [Diag] Automations Screen [Automations] I’m also talking to LANnouncer over direct TCP and can announce any alarms, strings or any string I write on the PLC all over the house. Ive mainly focused on the heating and diagnostics screens and everything else …

I can design a status on one of my screens for the water softener based on this dry contact and alarm on my HMI/announce over LANNouncer when the salt is low. Here’s 2 pics of the sensor installed.
