This is product is discontinued and replaced with the ZEN73. What does that mean?

If your switch works well manually but Z-Wave control isn't there, it may be a connectivity or range issue. 

Your Zooz switch is a Z-Wave Plus device that has range of 100 feet (line of sight). However, range can be shortened by interferences like metal elements, large furniture, and thick walls. Ultimately range is determined by the specific structure of your home and the strength of your mesh network. If you're seeing connectivity issues with your switch, here are several things to try:

1. If there's a way to refresh your Z-Wave network, give refresh a try. This will reset the connections between hub and switch, and help your hub find the most effective communication route to the switch.

2. Try excluding and re-including the switch directly from the installation location with nothing moved around. Just like network refresh, maybe the hub hasn't found the most efficient communication route to the switch; exclusion can help revitalize those connections. 

3. If you have a Z-Wave signal repeater on hand, try installing it between the switch and hub. A signal repeater is any non-battery powered Z-Wave device: plugs, switches, relays, anything that doesn't rely on battery for power. The repeater should give the signal a boost and help your hub establish solid connections with the switch.

4. Check the material of your switch box. If it's metal, this may be the source of the issue - especially if you've never had good connectivity between the switch and hub. Metal is really effective at disrupting Z-Wave signals; since the switch is essentially encased in metal, it can prevent signals from being sent or received. Adding a Z-Wave signal repeater as mentioned above would be good to try if you have a metal switch box. 

If none of the above solves the problem, please let us know! That's what we're here for!
