Temp Sensor for Hot Tub?

[Badger98]

Hello all,

I'm still just a few months into Hubitat usage. I have all of my bulbs and switches integrated, and I'm starting to branch out into other areas.

One problem I have is a semi-portable hot tub that we use regularly, but it is prone to shutting down without us realizing it (staying off after a power failure, auto shut-off after several days without usage, etc.), and it takes forever to heat back up. I'd like to find a temperature sensor I can throw into the hot tub and have it alert me when the temp drops below, say, 100 degrees, which is a sure indication that the heat/pump unit has shut down. Any recommendations for a sensor like this?

Thanks!

I'm afraid I don't have any suggestions for you so sorry I can't be of any help.

I am currently looking for a suitable temperature measuring device that would allow me to monitor the temperature of the hot water in my hot water cylinder tank.

Therefore I would also be interested in any recommendations.

I don´t have this running right now, but on my Vera I used a Fibaro door/window sensor which has an additional input for DS18B20 temp sensor. Temperature sensor | FIBARO Manuals

You can get waterproof sensors to use in your hot tub. This is what I was using.

When I first got the Hubitat (over a year ago) there was no good driver for this sensor and the batteries simply were emptied really fast, so I abandoned it at the time. I haven´t looked at this for a while.

Fibaro also have what they call a "smart implant" which can take sensor input. https://www.fibaro.com/en/products/smart-implant/

I believe this smart implant is a new version of their old universal binary sensor. I use quite many of these old types and they work really well. You can daisychain up to 4 sensors to one device.

Temp sensor w/ external probe support?

I’m looking for a temperature sensor I can use to monitor my water supply lines (to prevent freezing during winter months). I’m thinking an external probe attached directly to the outside of the pipe would be the best solution. Is there a “best” sensor out there that has Hubitat support?
