We all know the benefits of a therapeutic power-cycle of a SmartThings Hub, Computer, Router/Modem, SmartTV, SmartPhone, etc.
Just wanted to share a solution for an odd SmartThings behavior we experienced.
Your results may vary, but I would strongly recommend following the Step-By-Step below if you’re experiencing communication issues that aren’t resolved by the traditional power-cycling/reboots.
We have a house with 8 Schlage Smart Deadbolts, and various other z-wave and wi-fi devices.
All 8 Schlage Locks went offline at once and would NOT come back online. Upon power-cycling the Locks, they would come online, but wouldn’t respond consistently to commands and were very sluggish (at best).
Tried the traditional fixes… like in this order:
- Pull Batteries from Schlage Locks
- Power-Cycle Wi-Fi Modem/Router
- Power-cycle SmartThings Hub (including internal v2 Hub Internal Batteries)
- Z-Wave Network Repair
Z-wave Light Switches seemed to work OK, but were a bit sluggish.
It occurred to me that even though we were power-cycling the various key components, there was still an extensive Z-Wave Mesh Network which remained active throughout the home across 42± Light Switches which were never reset.
With that in mind, we proceeded to perform a Whole-House Power-Cycle (Reboot)! Turned Off the Main Electric Circuit Breaker (killing power to ALL AC-Powered Z-Wave Devices that weren’t on battery backup). Unplugged some Z-Wave Device with Battery Backups. Waited 2 minutes. Restored Power. BAM! Almost instantly, all 8 Schlage Locks came back online and were VERY responsive!
So, that being said, here’s my complete Step-By-Step for a truly therapeutic Whole-House SmartThings Reboot:
- Unplug Power from SmartThings Hub (note v2 Hubs have internal batteries which need to be removed)
- Unplug Power from Wi-Fi/Modem/Routers
- Unplug any SmartDevices from Battery Backups
- Note: Battery-Powered Z-Wave Devices do NOT act as repeaters so are not part of the Mesh Network per say, so we did NOT remove batteries from 24± Z-Wave Devices. But as @JDRoberts points out here, a Battery-Powered device could also create Network Issues. If you have a lot of Battery-Powered Devices, perhaps try this step-by-step first by power-cycling all of the AC-Powered devices to see if it solves your problem. Then consider a Round #2 by also pulling batteries from all of your Battery-Powered devices. Of course, if you only have a handful of Battery-Powered devices, go ahead and pull them in Round #1. We just weren’t keen on going around pulling 24+ batteries and in our case, the AC-Power Cycle did the trick .
- Turn Off Main Breaker at Circuit Panel
- Wait 2 Minutes (up to 5 minutes perhaps)
- Turn On Main Breaker at Circuit Panel
- Power On Wi-Fi/Modem/Routers
- Power On SmartThings Hub
