if you're using an anonymous timer, then it is difficult to access it later. you might have better luck if you set an id to reference later.

timerId = setTimer(float time);

function updateTimer(timerId) {};

maybe wrap that in a class, and use that when using Siri. you just have to speak the class definition first.

Hey Siri! set a timer using myCustomClassTimer!

It does have that ability on the HomePod minis that I have around the house. If a timer is set on one of them and then I want to reset it or add minutes to it, I can do so (but only when that HomePod mini hears me).

It works on watch and HomePod only.

The inability to set multiple simultaneous timers is annoying. I compensate by setting multiple alarms. "Delete all my alarms" works when I'm done, but it's certainly a hack.

"hey siri, start a 10 minute timer for the oven"

"hey siri, set a 30 minute timer for the rice."

it works just fine for me, use it all the time.

Doesn't work for me. I get this:

>There's already a [number] minute timer. Replace? Confirm/Cancel

Running iOS 16.1, so unless they added this feature in the last few months I'm not sure why we'd see different results.

edit: Perhaps you're using HomePod? Apparently Siri on HomePod supports multiple timers, while Siri on iPhone does not. Goofy.

My Apple Watch supports multiple timers, and yet my iPhone does not (iOS 16.4.1).

I mean, I guess a watch is supposed to be for telling time or whatever, but this is just a weird feature omission…

siri definitely has multiple timers. BUT you can only have two though and it only works on Apple Watch and HomePods.

I know, right?

Also a little known hack to set a timer you don’t have to say the whole thing just press the Siri button or say hey siri ‘n minutes’ and it will set a timer for n minutes.

On Alexa I run many times simultaneously. Didn't know it was a special feature. I just name them.

Latest update(?) it quit announcing expiration by name if only one was running. Just beeps, and maybe I forgot what it was supposed to be timing. Annoying.

Especially annoying if more than one person in the house is setting timers.
