Trouble with timers surviving a restart

penguinpatrol · November 23, 2024, 3:28pm

hey all,

i have set up an extremely over complicated alarm system as i am terrible at getting up

i have a repeat to send Alexa notifications and then a delay to wait before resending them, of course this means if i restart home assistant it gets cancelled in its tracks - so i have managed to set up a timer system for it to start a timer wait for it to complete and then continue the repeat

i thought since timers survive restarts if i reset home assistant midway through the delay timer it would have no issue pausing the timer and then when its all restarted continuing the timer and continuing the alarm (or at least being re-triggered by a state change from active to idle) but everything i do just does not survive a reboot

its only a 10 second delay and i had thought having a restore timer would pause it and then resume it on reboot but after watching a test 5 minute timer it just keeps ticking so i think that could be an issue?

any help would be appreciated - i will post the yaml if anyone needs it but lie i said its extremely over complicated so it may just be a big mess

(i do have a very simple workaround of just retriggering when home assistant boots but i would like to know if i can do it this way or at least understand why it isnt working)

We can better help if we see the yaml code instead of a screenshot of the UI.

Does that look right to you?

penguinpatrol · November 23, 2024, 4:09pm

i noticed that but i had copy pasted it from another user so i knew it looked wrtong but wasn,t sure

penguinpatrol · November 23, 2024, 4:10pm

it looks fine in the visual editor which is what i mainly use

penguinpatrol · November 23, 2024, 4:15pm

doesn’t seem to have changed it still doesn’t to anything on boot

As posted above, with a literal backslash character and letter tee, it corrupts the event’s name.

My understanding is that you probably had a literal tab character and, during the copy-paste operation, it was represented as \t. It exists within the double-quotes so it’s interpreted as part of the entire string (thereby defining a non-existent event name).

Ensure the timer’s restore option is enabled and you understand how it causes an active timer to behave after being interrupted (notably its finished_at property).

If an interrupted active timer fails to automatically resume its remaining countdown after a restart, then you may need to report it as an Issue in Home Assistant’s Github Core repository. In fact, there appears to be an existing open Issue about a failure to resume.

Timers dont always fire/cancel/finish when in an automation

integration: timer

### The problem I have an automation which triggers when a switch is turned on …or off with two outcome paths based on trigger IDs. One for on and one for off. each part of the flow has a timer associated: turn on the switch - turns on the timer turn off the switch - cancels the timer However, the timer doenst actually do as above every time, it is unreliable. I'm using an official Timer helper. ### What version of Home Assistant Core has the issue? core-2024.11.1 ### What was the last working version of Home Assistant Core? _No response_ ### What type of installation are you running? Home Assistant OS ### Integration causing the issue Automation/Helper ### Link to integration documentation on our website https://www.home-assistant.io/integrations/timer/ ### Diagnostics information _No response_ ### Example YAML snippet _No response_ ### Anything in the logs that might be useful for us? _No response_ ### Additional information _No response_

i removed the backslash and cleaned it up to be identical to the .finished trigger (which does work fine) and it still does nothing, and the timer is selected to restore, i dont know much about timers and at a glance through the wiki and such i cant find anything helping me out so that’s why I’m asking here,

i may be missing something with how the timer works or how the automation is set up all i know is that a 5 minute timer does continue after restart but the 10 second one wont so it wont retrigger the alarm when home assistant starts up and I’m unsure why or any ways to work around this to get the automation to restart using a timer after i reboot home assistant

penguinpatrol · November 23, 2024, 4:42pm

i would report an issue but with my limited knowledge i dont think i would be able to help with finding what the issue is nor how it could be solved

KruseLuds · November 23, 2024, 4:47pm

I have alot of complicated scenarios that are in any one of various states when home assistant is restarted. For each different thing that might be going on when HA is restarted, I have automations that run on start. For example, for a light that goes off when a timer is finished, I have this sort of thing in an automation that runs at sartup: If automation “x” has enabled drop-down = “Enabled” and the light is on but timer is inactive then restart the timer with the duration specified by the slider… If the timer is active but the light is off and automation enabled then just cancel the timer, or if the timer is active but the automation is marked as disabled just cancel the timer, etc., etc…

This way I can be sure that when HA is restarted, everything is back up and running in the proper state.

Hope that helps

BTW the trigger for when HA is shut down - I have never been able to use, seems like it is a weird unuseable one-off (as you might be trying to trigger an automation with devices that are unavailable - because HA is shutting down!).

Probably because your system takes more than 10 seconds to restart. The timer is considered to have finished during the startup phase. Review the docs about finished_at.

From the documentation:

If an active timer was supposed to end while Home Assistant is stopped, the timer.finished event will fire on startup for that timer. The finished_at property in the event data will provide you with the time that the timer was actually supposed to fire which you can use in automation conditions to decide whether or not to act on it.

If the 10 second timer was supposed to finish while Home Assistant was in the process of restarting, on startup the timer.finished event will fire. If it doesn’t then it’s a bug (all of this assumes the timer’s restore option is enabled).

i had a feeling it had to do with the short time and how long ha took to restart as far as i am aware timer.finished does not trigger after a restart (but does when run normally) i’ll give this a quick recheck and verify

(also yes it is triggered to restore like i said)

Then it’s not behaving according to its documentation and is a bug; report it as a new Issue or, if there’s an existing open Issue that describes the exact same faulty behavior, add a comment to it describing your observed failure scenario.

just rechecked and it seemingly definitely isn’t triggering so i will do that! thanks for the help

Pure speculation:

The bug might be something simple like the timer.finished event fires before Home Assistant finishes loading all automations. In other words, the Timer integration is loaded before the Automation integration. So by the time your automation is loaded, it’s too late to detect the timer’s event.

i have also been wondering this exact thing as i was testing, wondering if it triggers before the automation actually has time to start working
