Waiting to see if the app can be installed on 2 different phones for the same serial number ETM so my wife can also monitor the temp before she swims.
I have it on my phone, my wife's phone, and I will check online through a internet browser on my laptop as well.
I purchased 2 probes, one for my pool, and one for my air temp. So now when I want to check weather, rather than seeing the temp at a random weather station on weather.com, I just look at the temp at my house.
Long term, because I am a gadget geek as I started this thread with, I am going to use IFTTT and a spare Raspberry Pi that I happen to have to make a small outdoor 5" LCD that will display the pool temp out by the pool as well.
