It has gotten to the point where Z-Wave is not at all reliable. I have multiple Z-Wave devices and repeaters but at least twice a week I have to do a Z-Wave repair as one or two devices don’t take commands. Once the repair is complete the devices all work.
I am suggesting that at a certain time very early AM in each time zone or from the mobile app on a schedule a Z-Wave repair be performed daily.
This problem has not gotten any better or worse, but this should be pushed through as quick as possible.
