I would like to monitor the temp in our hot tub and get an alert if the water temp goes below a certain temp. This time of year if the heater were to stop working you can have a real mess on your hands with frozen/damaged pipes & pumps.
I’m looking at the first gen of the Fibaro FGK-101 which allows for external probe attachment. I was looking to pair it with the DROK DS18B20 prob and just hang it over the side of the hot tub into the water.
I started thinking about a way to make this install cleaner…The hot tub has a built in probe that attaches to it’s motherboard so it can monitor it’s temp. Would it be OK to tie into this same probe?
