Cannot connect Aeotec Water Sensor 6 to Smarththings

I have an Aeotec Water Sensor 6 whose battery died. I replaced batter but now cannot pair with Smartthings. When I look at the hub → connected devices, I can see it. But, it is not listed on the home screen of Smartthings.

Hope that makes sense…

Any suggestions?
Thanks much!

look in Devices > No room assigned or in All Devices

Yup!! That was it. Thanks for the quick help!
