SmartThings Swimming Pool Solar Heat Automation - DIY

As a safety net for the battery dieing (or other reasons for the sensor going offline), you might want to consider adding something like this to you piston. It’s saved me a few times when the AA batteries on my modified sensors die.

That’s a great idea. I’ll take a look at adding that for all the sensors. They are all solar charged now (5 of them) and have been quite reliable…however anyone using ST for awhile now knows that issues arise from time to time.

The HUE light system is the only automation bit that has required zero fiddling/resets/frustration since installation 3-4 years ago. I have about 30 lights on their hub.
