Thanks for all the responses everyone, really appreciate the help.
@theedpope, I have GE paddle switches/outlets (3 z-wave & 3 zig-bee) which got connected without a problem and are working with on the Smart Home Security app. These along with the bunch of ST’s motion and multi sensors, all working in harmony. Also, I checked Aeon’s website on firmware upgrade and they say “This firmware is not for the Multisensor Gen5.”
@Jimxenus, i have tried to add the sensors sitting right in front of the hub. Tried both the ways as per the 2 links I found. Also, the general exclusion doesn’t seem to work bc it just keeps going looking for something.
I will try connecting with the USB and see if that makes a difference…
Are there any other products out there which offer the same features & functionality?
