Read pH & PPM levels from sensors on ST


I’m searching for wireless devices (cloud/ zigbee/ zwave) with ST integration that continuously measures water levels of pH and PPM (or EC/TDS) .

  1. I can see that ST supports ph sensors - does anyone know which brands / models of sensors I can buy that actually utilize this api? I can’t find any device that officially does that.

  2. I found this device made by Caperplus, which two Aliexpress sellers claimed got ST integration (its app looks like a white-label copy of Tuya app I think), but I can’t make out if I could access the actual pH & PPM values on SmartThings. Does anyone have any experience with this device?

Any other ideas on reading pH and PPM via ST would be highly appreciated.
