This afternoon, all of my mains-powered z-wave device became unreachable. ZigBee and battery-powered z-wave device all seemed to be working. I tried running the z-wave repair and it reported every single mains-powered z-wave device as: Failed to update mesh info. I rebooted the ST hub a couple of times with no effect. I then pulled the power to the hub for several minutes. After repowering the hub everything was working again.
Everything was working fine for several days, I made no changes, yet I lost the z-wave connection to several dozen devices. Any ideas on what happened and how I can prevent it from re-occurring?
