I was away from home for a bit over 24 hours (about 27, to be exact). Everything was working fine when I left home.
When I came home, all sorts of lights were on. We had left someone working at the house, so I figured they just hadn’t turned the lights off. But on further investigation, I found that anything that is beyond the physical on/off of a switch is either not working, or working sporadically.
We use Amazon Echo a lot. “Alexa, turn on Kitchen Counter.” Alexa says “OK”. Nothing happens. Smarthub log shows command received from Alexa but does not show any on/off action. Or, sometimes, the light goes on, but only after a long delay. (Yes, beyond any kind of reasonable cloud delays - I’ve been there before.) From the smartphone app, the new version just hangs for a while and then pops up “A network or server error occurred. Try again later.” The classic app just does nothing. Except that sometimes they work, though usually with a delay.
Other local routines don’t work at all - in the Smart Lighting app, I have two rooms which have automations that say:
- Which devices do you want to control? < list of smart lights >
- What do you want to do? Mirror Behavior
- Mirror which switch? < name of master switch >
Neither one works anymore. And, most (but not all) of the lights I found on when I returned home were the ones controlled by these two automations, so I suspect that the person here working tried to turn them off but it wasn’t working. (Update, about 20 minutes later - now at least one of them is sometimes working.) (Update 2, about 10 hours later - I should add that the smart lights being controlled by the automations are able to be controlled individually via the smartapps, so the hub is clearly able to communicate with them.)
I have a contact sensor on the closet door. Open the door, light goes on; close the door, light goes off. Can’t be any simpler. Except now nothing happens.
I’ve done Z-Wave repair on the hub several times. I’ve rebooted the hub several times, both from the hub utilities in IDE and by power-cycling the hub (including removing batteries). I’ve power-cycled my WiFi router.
I can go into the Alexa app and “forget” all the devices. It then successfully discovers them again. I had noticed recently that once in a while, when I said “Alexa, turn on Stairway LIght” (for example), Alexa would respond “Stairway Light isn’t responding. Please check its network connection or power supply.” But if I tried again, it worked. I have at least one switch right now that I am consistently getting the “not responding” message on from Alexa.
The only thing I’ve seen that seems at all out of the ordinary is the following in the hub event log after I reboot the hub:
Does anyone know what it means?
All that’s left that I can think of is that the hub has just plain gone bad. I’m really hoping that’s not the case, but I’ve ordered a new one (V3) that is supposed to be here Tuesday (it’s currently Sunday evening). Besides the hassle of replacing the hub, I’m going to be traveling next weekend so I’d be under the gun to get everything back up to speed. I assume I have to rediscover all the devices on the new hub? And reauthorize everything to SmartApps? And fix a whole bunch of WebCoRE routines that will be broken?
Tell me what I’ve overlooked that will fix the issue quickly and painlessly.
