I was able to address the problem I was having saving pistons via a core code update. I am still requesting assistance with two issues:
First, my presence sensor appears to be working, which is to say the Smartthings device list accurately depicts whether our phones are home or not, however, the piston above fires when both our phones are present. It shouldn’t so the logic of the code above appears to be incorrect. Any ideas?
Second, I added some new sensors which are showing up in the Smartthings hub but are not showing up in WebCoRE. I assume those should be included automatically, but they are not available.
Any advice how to address these issues would be appreciated.
