I went on vacation last week and set up a vacation mode that was supposed to auto turn off and turn on lights. When I left everything worked great. Now I’m home and more than 50% of my things just stopped working. Some are ge link bulbs, some are ge zwave switches. The actual physical bulb or switch works but I cannot control them at all through smartthings.
Any ideas why this would just happen out of no where, and ideas on how to fix it?
Unfortunately this is mostly z-waves fault. It is an ancient technology (i think it was released in the 70s) that actually has a ton of bugs in it. As a hub manufacturer you are perpertually walking on egg shells with z-wave. Here’s to hoping that zigbee becomes and more widely used protocol. It is much more stable (and about twice as fast on the communication side)
Rebooting did nothing. When I had micasa verde I never lost control of any zwave device. I love the idea of smartthings but it’s getting so finicky. Every week there’s an outtage or something stops working. I’ve had to delete (not always an easy task) things, re-pair them only to have to do it again a few weeks later. It’s getting frustrating!!
I think you have to check your facts. ZWave was introduced in North America in 2008 when Sigma Designs acquired Danish startup ZenSys. You may be confusing it with X10, which has nothing to do with Z-Wave, but rather is a grand daddy on Insteon.
You are correct I was mistaken with the dates of x10. My apologies. Thanks Geko
Regardless of my incorrect dates, zwave tech has a TON of shortfalls that no smart solution manufacturer can control. For instance a inherent flaw where you can’t ping the device too often without it freezing up and the device REQUIRING a hard power off to “reset” itself. Smartthings ran into this a couple months ago. They may still be within the wrong range with device checks. (P.S. Zwave does not publish this value so it’s hard to discern what it is.)h
As for you having to re-add the devices after the upgrade, I’m going to throw my hands in the air lol. That week/weekend was just bad lol. No doubt about it. I say we should just forget that week lol. Bad times and negative feelings and talk tend to have a way of being poisonous.
Yes, apparently they’re counting time before ZenSys was acquired. Anyway, Z-Wave and Zigbee are about the same age. Zigbee spec was published in 2005 and I actually started working with XBee (then MaxStream) samples in 2006.
They are also on non-dimmer smart switches. Yes, this is a safety feature. When traditional switches are turned off, you can safely replace a light bulb without getting shocked. Air gaps are added to dimmers and smart switches because this is no longer the case.
According to this post, even this has potential failure:
I agree with others that an air gap isn’t very useful.
In addition, I have had switches dropped from the network where cycling the circuit breaker worked when recycling the air gap did not.
