I have two Smartthings buttons setup to turn 1 light each in and off. They have worked great for mo this and today they both stopped working. If I pull up the app on my phone and press the buttons the app shows that they were pressed but the lights don’t toggle. I can turn the lights off and in front the app but not from the buttons. I power cycled the hub and the same behavior occurs. I have a 2nd Gen hub part# STH-ETH-250 on firmware 27.00009 controller 1.7.38-21. And the buttons are on controller 1.7.37-210
I’m so frustrated that I’m tempted to factory reset it and start over since it is as acknowledging the button presses but not acting on them. If that dont work throw it all away and buy from a company that makes products that work.
