Not sure if I missed it, but is it possible to set up an alarm timer on the Assistant from within an automation?
I currently have an automation to set up my lights for a nap and would like to wake me after an hour. Right now I have to command it to set up a timer manually, but would like to do it automatically by including it into the automation.
I think that right now this isn’t possible, but it doesn’t hurt to ask, eh? 
just add playing a sound into your automation after an hour 
It is possible, this is how I do it:
data:
duration: "01:00:00"
target:
entity_id: timer.kokstimer <--- Your entity goes here
action: timer.start
But will it then run on the voice assistant, or on home assistant? The latter isn’t my problem, but the first one. I would like it to act like if I set the timer using voice - showing the remaining time on the blue ring and play the alert when the timer is triggered.
In the automation gui, I noticed that I can set a trigger, but it requires an entity and it seems to be independent from the Voice Assistant?
Setting it up to play something after an hour would be an idea, too. But if it’s possible to use the VA timer, that would be my preferred option.
Right now those are separate things.(the timer is apparently implemented on the Vpe itself and doesn’t have an external entity… Yet) There are other threads out there where folks have identified the function in the vpe source but I think they’ll need to make an edit to expose those as entities in HA before you get what you want (I’d personally like timer set timer start and stop, recycle, reset and control of both the color and relative fill of the ring if not expose it as a WLED device)
Aah, voice assistant … I have no idea
