Room lighting automation suddenly stopped working. Why?

I have a simple automation in room lighting that turns on lights x min prior to sunset and turns them off at y time if not already turned off by something else.

It has been working flawlessly for over a year.
2 days ago it stopped working.
I have not changed or updated anything on the hub.
I have not added, revised or removed devices, apps or automations in a few weeks.

What would cause this to stop working and what should I do get it working again?

ETA: Pasted log below. From the bottom up:
The log only shows about the last 20 hours; pressing "Show More" does nothing.
Log says it checked at 11:59 pm last night and light was already turned off; it was not; I manually turned it off at 12:13 am.
The other two entries from 6:06 pm today are me making sure the light is connected to Hubitat.

ETA: HE is on 2.3.6.146

What make/model device is the (I assume) plug that isn't being controlled properly? Zigbee or Z-Wave?

Turning the plug on/off from its Device page works normally?

You could try enabling the option in RL to turn off the device even if it looks like the device is already off...that could help if your device isn't reporting status correctly/promptly. But probably better to figure out why it isn't working as it did previously.

It's a Jasco Z-wave 2x plug in dimmer.

And can you answer the question above that I asked?

Sorry.
Yes, works fine to turn on/off from device page.
Also works fine to turn on/off from the dashboard.

Thanks.

Post a screen shot of your RL automation using the plug.

Also confirm nothing went haywire w/your hub settings due to the DST change...on Settings>Hub Details is the time and your location correct?

Well, 5 minutes ago, after not firing on or off for 2 days, the automation suddenly fired.
I guess it has fixed itself?

Not sure it had anything to do with DST, as that happened Sat night to Sun am, and the rule fired fine Sun, Mon & Tues.

It stopped working Weds, I thought it was a one off, but then it did not work on Thurs (yesterday). Yesterday it had the opportunity to turn on the light (which it has daily) which it missed, so I also set things up so it could turn off the light (usually other things turn off the lights earlier). When it also missed that I decided it was not working properly and posted earlier this eve. I guess I should have waited before posting...

Since the plug is a Z-Wave device, you could do the shut-down dance to clear your Z-Wave radio if this comes up again:

  1. Shut down hub
  2. Pull hub power cord from wall
  3. Wait 30s
  4. Plug in again and let it boot up

Also - is anyone operating the plug manually?

Mine also stopped working after one of the updates. Affected all timer events. Various devices. Manual on/off works.

You will need to provide more information, including the platform versions you moved between and additional details about the types of devices involved and your Room Lighting setup, i.e. screenshots.

What he said, we need more information.

They were specific fixes for timer based issues with rules that were included in recent platform releases. If your hub has not been updated to the most current platform release, that would be the most likely suggestion to fix your issues.

But please do post the information asked for above.

I am at the latest beta release. It stopped working about 3 updates ago. I was hoping a following update would fix it but it didn't. I am now in the process of re-saving all time based rules (and adding +/- 1 minute to them to force a change) to see if that fixes it. Not much more I can add except that while an update in the last 2 weeks did break this, the later updates alone don't fix it. Ran fine unattended since C7 came out until this.

Platform version: 2.3.9.150 HW: C7

The tedium with time based rules is that you need the time to arrive before you know it's not working.

Hmmm... Given an update would include a hub reboot I would not expect you would need to re-save the rules to re-establish the schedule, but worth a try. If that works, that may (unfortunately) be the solution, though unlikely....

Not happy to hear that. BTW the time of day is correct on the hub and all my timed events use fixed time of day.

Devices impacted:

  • Sengled Smart LED Strip
  • Two Sengled Smart LED Bulbs
  • Two NEO Green Z-Wave+ PowerPlugs

It can be a good or a bad thing.... The thing to do will be to test the theory with one or two rules. If it fixes them then it may be worth doing across all the affected rules, otherwise you can focus on another feature of the rules to troubleshoot.

Re-saving the broken timed rules has fixed the issue (even if we don't understand why it did). Glad to be back up again :slight_smile:
