Hello,

I’m tired of my crappy Aeotech multisensor 6 sending all sorts of false alerts or no alerts and or powering off for no reason. I have it usb powered and mounted outdoors to alert for motion after 10:30pm. I messed with all the available ways to adjust it and have several z-wave repeater plugs close. It’s never reliable. My question is could I use a wireless Z-Wave Multi-Input/Output Dry Contact Bridge in conjunction with a microwave based sensor to have more reliable motion detection on my driveway? Thanks for your responses in advance.

The aeotec is not rated for **motion** outdoors. (See the user manual). It would be less expensive and easier to just switch to the zooz.
