Does anyone have any recommendations for temperature probes that can reliably be integrated into Homey Pro to monitor water temperature in copper or PEX plumbing systems? I want to monitor a hot water recirculating loop and shut off the pump when the water hits a preset temperature.

I apologize if this has been covered in another post - I may have missed it…

Thanks!

Thank you! This got me on the right track.  
I picked up a Shelly 1 Plus, a Shelly Add-on Plus, and some DS18B20 Sensors. This combination of units should do exactly what I need. Now I just need to get the recirculation loop plumbing done…

No homey flow for that task 🤣
