I have the 2nd generation echo show (is a zigbee hub). I was able to have my multipurpose sensor discovered the first time around. I installed the Smart Things app because Echo on my phone does not give notifications if the device is open (how incredibly stupid for a security system!!). I also enabled the smart things skill.
Now that I deleted the device to start over again it won’t discover it. Truly frustrating. I removed the battery, pressed the pinhole, deleted the ST app, disabled the ST skill, and tried having it discovered about 30 times to no luck.
Can someone from Samsung please help me out? I’ve spend over 2 hours pulling my hair out.
