I just installed my first two z-wave devices (Zooz ZEN21 On/Off Switch) on a smartthings hub and it was an awful experience.
Reading through the forms I see a lot of people saying hey my X number of z-wave devices went offline/not responded or I could see the status updating but not control the device. I worked with support and spend x hours removing and rebuilding my devices/rules to get it working again and now its down again.
I’m new to smartthings/ZigBee/z-wave and from what I’ve read z-wave is more stable than ZigBee but my ZigBee devices while not perfect at least came back online.
Based on what I observed and my IT experience it looks like issues between the versions of Z-wave protocol running on the Smartthings hub and the device.
My smartthings hub (v2, US customer Rev E) is running 18.00022 which is using Protocol Version: 3.83)
The Zooz is running zwv:4.05 lib:06 cc
What is the roadmap/timeline to bring smartthings to v 4.x standard?
I observed many flaky issues all related to handshake type issues:
- Rebooting just the hub makes the z-wave device totally not respond to a re-association request. No status updates or device control.
- Rebooting the z-wave device (trip circuit) semi brought the device back online. I can see its correct on/off status but I cannot control it.
- Removing the device via the android app makes it disappear from the hub with a successful removal message but it is not did-associate on the remote device. I had to do a second round of general device exclusion and saw the device disassociate and reset. I could then finally add it cleanly but any reboot of either the switch or the device but it back in a fubard status.
- The good news is that turning on the breakers to power up the switch while the hub was rebooting brought everything back without a reblast of the devices/rules.
I see there was a mandatory memo issued on the “Security 2” framework
Are these types of voodoo issues due to bugs in the code due to a rush to meet the, Z-Wave’s technical certification program deadlines or is it due to smartthings being so far down rev? These look like classic handshake / I don’t know you type issues.
Begin totally non related Rant:
Why does Bixby/Samsung connect not control all devices attached to smartthings? Samsung should be embarrassed that both Google and Amazon can do it and they cannot…
