I would like to have it check the sensor for when it not only crosses but also is above the value 10. Then to keep sending me warning messages until its below.

  - entity_id: sensor.fridge_temp_meter_XXXX_temperature

To format your text as code, enter three backticks on the first line, press Enter for a new line, paste your code, press Enter again for another new line, and lastly three more backticks.
```yaml
example: here
```
Don't forget you can edit your post rather than repeatedly posting the same thing.

You could have the automation trigger on every state change of the temp sensor, or you could set up a time pattern trigger (and in both cases, keep the condition you have)

when i try and edit post it just goes ot the post title....

west robin Aug 5, 2025, 2:01 PM

#

The first option might result in tons of notifications, so you could add a delay to the end of the action for whatever you'd want the cooldown to be and change the automation mode to single

#

jovial sundial when i try and edit post it just goes ot the post title....

you would want to edit the first message, not the post

jovial sundial Aug 5, 2025, 2:04 PM

#

Done, I want it to notify me every 30 seconds and then allow me to disable it. So as an automation I can disable it. But hwo to get it to recheck. Yes I could get it trigger to do it on a state change. let me test that.

#

Actually ill try the time pattern first

#

time pattern set at 30 seconds. Works great

#

So this will repeat every 30 second, when it meets the condition, until i disable the automation

#

Now if i wanted to add in a dashboard toggle? Would that be a toggle helper linked to the automation? (havent played with HA for a while)

west robin Aug 5, 2025, 2:10 PM

#

You could add the automation entity itself to the dashboard

flat depot Aug 5, 2025, 2:10 PM

#

You need to have 2 triggers in your automation. 1st - time pattern sensor /30 sec, 2nd - when sensor crosses value 10.

west robin Aug 5, 2025, 2:10 PM

#

assuming you want to turn the automation itself on and off

flat depot Aug 5, 2025, 2:10 PM

#

Assign them own IDs

west robin Aug 5, 2025, 2:12 PM

#

flat depot You need to have 2 triggers in your automation. 1st - time pattern sensor /30 se...

they don't need the second trigger, but adding that would make it trigger immediately when it crosses the threshold instead of waiting for the next time pattern trigger (which might be worth it)

flat depot Aug 5, 2025, 2:13 PM

#

2nd trigger will set helper switch ON

west robin Aug 5, 2025, 2:13 PM

#

yeah that would be a good idea to include as opposed to setting up another automation to turn on this automation

flat depot Aug 5, 2025, 2:13 PM

#

automation itself will always in working state

#

both triggers work in one common automation]\

#

time pattern trigger checks heper switch state.

#

sensor trigger sets helper On iv > 10

#

if > 10

west robin Aug 5, 2025, 2:16 PM

#

jovial sundial time pattern set at 30 seconds. Works great

time pattern trigger set to /30 will only trigger once per minute (since that will trigger when the seconds value is divisible by 30). you would need two separate time pattern triggers to actually trigger every 30 seconds (one with seconds: 0 and another with seconds: 30)

jovial sundial Aug 5, 2025, 2:16 PM

#

ive created a helper toggle and added it to the dashboard. So scrap that and just add the automation direct?

west robin Aug 5, 2025, 2:16 PM

#

unless you're turning the automation on/off with another automation, you can do what pyzone suggested

flat depot Aug 5, 2025, 2:16 PM

#

you can manually set ANY state for helper switch

jovial sundial Aug 5, 2025, 2:17 PM

#

west robin You could add the automation entity itself to the dashboard

done

#

ill scrap the helper toggle

west robin Aug 5, 2025, 2:17 PM

#

are you turning the automation on/off with another automation though?

flat depot Aug 5, 2025, 2:17 PM

#

if you don't need this auto anymore - then you OFF auto where you can

west robin Aug 5, 2025, 2:17 PM

#

if not, you'd want to do what pyzone is suggesting

jovial sundial Aug 5, 2025, 2:17 PM

#

west robin unless you're turning the automation on/off with another automation, you can do ...

no its all in a single automation

west robin Aug 5, 2025, 2:18 PM

#

then yeah, what pyzone said would be a good idea

jovial sundial Aug 5, 2025, 2:18 PM

#

I just want to turn it off and on as I know the door is left open. I then turn it off until the temp has gone back to normal.

flat depot Aug 5, 2025, 2:19 PM

#

i have made a many autos like that

jovial sundial Aug 5, 2025, 2:19 PM

#

west robin time pattern trigger set to `/30` will only trigger once per minute (since that ...

a minutes fine, i just need it to repeat until i have noticed the door is open.

jovial sundial Aug 5, 2025, 2:19 PM

#

flat depot You need to have 2 triggers in your automation. 1st - time pattern sensor /30 se...

dont i have that?

#

whats pyzone suggestiing?

#

#

I have two triggers, one for above 10 and 1 for every 30 sec (1 min)

flat depot Aug 5, 2025, 2:22 PM

#

you need to assign individual IDs to each trigger

#

3 dots at right

jovial sundial Aug 5, 2025, 2:22 PM

#

Is that in the UI or YAML?

flat depot Aug 5, 2025, 2:22 PM

#

ui

jovial sundial Aug 5, 2025, 2:23 PM

#

Trigger ID? had no idea that was there

flat depot Aug 5, 2025, 2:23 PM

#

yes it's here

#

type any letters/ better do so to understand yourself

jovial sundial Aug 5, 2025, 2:27 PM

#

as in a reference to the trigger like an entity name?

#

eg "trigger_fridge_temp_Above_10"

flat depot Aug 5, 2025, 2:28 PM

#

you mean how to name it ?

jovial sundial Aug 5, 2025, 2:28 PM

#

no I mean why am I renaming the ID and not the trigger?

#

ie why ID and not name?

#

flat depot Aug 5, 2025, 2:29 PM

#

rename is for visible heading in ui tabs

jovial sundial Aug 5, 2025, 2:30 PM

#

ah ok

flat depot Aug 5, 2025, 2:30 PM

#

id is for use in ciondition checking

jovial sundial Aug 5, 2025, 2:32 PM

#

oh , what would you suggest I name it?

flat depot Aug 5, 2025, 2:33 PM

#

try self-explaining shorts .

#

1st action in auto must be like

#

want to show a picture but don't know how to do iy here

jovial sundial Aug 5, 2025, 2:35 PM

#

just copy and paste with a screenshot

#

screentshot, paste into chat

#

#

printscreen key (might need to be enabled in windows settings)

flat depot Aug 5, 2025, 2:35 PM

#

jovial sundial Aug 5, 2025, 2:36 PM

#

ah yes, i see,

flat depot Aug 5, 2025, 2:36 PM

#

you'll have 2

#

see "triggered by init" : it's trigger ID

jovial sundial Aug 5, 2025, 2:37 PM

#

yup thanks

#

Thanks everyone, job done!

#

Fridge now cooling from 21C

#

Ah one thing

#

What if I do the same for the freezer but its a negative number?

#

Is it above or below -19?

flat depot Aug 5, 2025, 2:39 PM

#

i think no diff

jovial sundial Aug 5, 2025, 2:39 PM

#

above -19 is -20 mathematically....

flat depot Aug 5, 2025, 2:40 PM

#

cooler is below

#

above -19 is -18

jovial sundial Aug 5, 2025, 2:40 PM

#

right but is it the below value or above value?

#

ah true

Hi All
I'm building a temperature probe by ESP Home with DS18B20 probes. I've created an automation to trigger an alarm when the freezer temperature rises to -16°C.
I've programmed the alarm to repeat every 15 minutes if it's not turned off. This is to force a visual check of any food that needs defrosting.
The temperature probe records temperatures regularly, but the alarm does not go off because the probe is above the threshold.
I found here a discussion that seems like my problem.... did you found some solution to trigger automation?
below my code:

description: Invia notifiche ogni 15 minuti se la temperatura supera i -16°C
triggers:
  - entity_id: sensor.sonda_tempconcelatorecantina_congelatore
    above: -16
    trigger: numeric_state
conditions:
  - condition: state
    entity_id: input_boolean.allarme_congelatore_attivo
    state: "off"
actions:
  - target:
      entity_id: input_boolean.allarme_congelatore_attivo
    action: input_boolean.turn_on
  - repeat:
      until:
        - condition: state
          entity_id: input_boolean.allarme_congelatore_attivo
          state: "off"
      sequence:
        - data:
            title: :warning: ALLARME TEMPERATURA CONGELATORE
            message: La temperatura è sopra i -16°C. Controllare!
            data:
              push:
                sound:
                  name: default
                  critical: 1
                  volume: 1
          action: notify.notify
        - delay:
            minutes: 15
mode: single

#

I also checked the off state of the entity input_boolean.allarme_congelatore_attivo
This entity its used to acknowledge the alarm manually, in this way who manage the alarm can reset it. But like I wrote above my automation doesn't work, I don't understand where is the problem in the code.
Suggestion?

#

Your automation will trigger when the temperature transitions from below -16 to above -16. If you created the automation when the temperature was already warmer than -16 it won’t fire.

thorn ledge Sep 25, 2025, 11:54 AM

Another suggestion, unrelated to your issue, is to avoid long-running automations. Reloading automations or restarting HA will stop the automation, and it won’t restart. I suggest something like this:

description: Invia notifiche ogni 15 minuti se la temperatura supera i -16°C
triggers:
  - entity_id: sensor.sonda_tempconcelatorecantina_congelatore
    above: -16
    trigger: numeric_state
  - trigger: state
    entity_id: sensor.sonda_tempconcelatorecantina_congelatore
    to: "on"
    for:
      minutes: 15
conditions: []
actions:
  - target:
      entity_id: input_boolean.allarme_congelatore_attivo
    action: input_boolean.turn_off
  - target:
      entity_id: input_boolean.allarme_congelatore_attivo
    action: input_boolean.turn_on
  - data:
      title: ":warning: ALLARME TEMPERATURA CONGELATORE"
      message: La temperatura è sopra i -16°C. Controllare!
      data:
        push:
          sound:
            name: default
            critical: 1
            volume: 1
    action: notify.notify
mode: single
