I reset the sensor by holding down reset for 30 secs, On my Android phone, I add the device, it sees it just fine, says it's included.
Return to main screen and refresh it 4 or 5 times to try and get drop down box to open so I can name it and choose room, Open and close app, screen never drops down. Ok Lets Try again. Reset, Add device, included in wifi, success. return to main screen and try to get drop box to show up by refreshing, Box drops down, I choose light icon in discovered devices drop down, it list everything in my house, I dont see motion sensor. Back out of that to choose different icon in drop down box. But it wont drop down again, no matter how many times I refresh. Try again, RESET sensor. Ok Device included, back to drop down box, Refresh screen, 3 times, drop down box never appears.
Sometimes I get all the way, assign it a room, choose lights to turn on, but wont turn them on or it will but then never turn's them off again.\
I have updated, rebooted, router, Phone, firmware, I once had all 3 working, but could not choose "turn off after 10 mins of no motion, The one that works now turns light off after a few mins no matter what I choose it the app. I have reset so many times, so many hrs, trying and trying, Turned to support, the forum,
I have a Pixel 3a, phone, I know it must be very hard getting things to work with all the different Phones, computers, and the weakest link, The people. ;] Thanks for trying, I really like your products but the universe is eating my lunch on the motion sensors.
