Custom Integration: Simple Timer (+Card)

Hi Arik,

First, I just wanted to say thank you for the prompt reply and kind words of encouragement. I realized learning something new and somewhat complex, especially at my age, would be a challenge. But, it’s nice to know right out of the gate that there are nice people here, like you, who understand this and haven’t forgotten that they were once new to this too. I genuinely appreciate that.

Also, thanks for the speedy update. Prior to the update, I had added the integration and selected the proper outlet beforehand, which did appear in the dropdown menu, I just wasn’t able to select it. But now it’s working just as I had hoped.

Thanks for your work on this. This integration makes it so easy. And, though I became a little frustrated with trying to figure this out, I also learned a lot in the process through trial and error (ok, mostly error). Also discovering as I go, like you said, just how powerful HA is. I have only scratched the surface and look forward to discovering as much as I can. I also look forward to your future work on this integration. Any suggestions I would make have already been raised here (size, customization). Keep up the great work and know that it is appreciated. :peace_symbol:

Hi Arik. Thanks for all the work you have put into this.

I am trying to create an automation that will automatically start a timer when a plug (switch) is switched on. This should also show in my dashboard’s card that I have created.

I have tried adding the “Simple Timer: Start Timer” Action and set the Entry ID to my plug (swith.lounge_plug). I also tried to use the Simple Timer’s entity for my plug (sensor.lounge_plug_runtime_01kkpvdh). None of these seem to set the timer for the plug switch to automatically switch off after the duration has been set. The Dashboard’s card does show the timer and the actual device isn’t switch off.

Am I setting the correct Entry ID for this action in my automation?

Thanks for any assistance with this.

The entry_id is a unique internal identifier for that specific timer configuration. You can find it by following these steps:

  • Navigate to Settings > Devices & Services
  • Find the Simple Timer integration card
  • Click on the specific timer instance (entry)
  • Click the three dots in the top right or next to the entry name.
  • Select Copy ID

I'm getting * Custom element not found: timer-card
Installed via HACS.
Then got to devices and add a timer to a water pump. It shows on the device as well on the integration.
But on Lovelace doesnt show the card type...

Hi, Does anyone have experience with this? There is a good YT video about it, but apparently something has changed:

Goal: I want to create a dashboard with buttons and various timers to control my air conditioning. However, the AC doesn't have a switch entity, so I need a workaround, because Simple Timer can only trigger switches.

What I've done so far: Created a helper switch (Boolean)

Linked the Simple Timer to the switch

Created a dashboard with the Simple Timer Card

But something isn't right yet. When I save the dashboard and start a timer, shouldn't the helper switch toggle its state? I want to use that state change as a trigger in an automation to turn off the air conditioning.

Where is the error?

I think you may have confused this with another card.

My Simple Timer integration already includes the card, so you don’t need to download anything else from HACS.

I know there is a “Simple Timer Card” available in HACS, but it has nothing to do with my integration.

Just make sure you select the correct card:

I was struggling with this as well until I saw your post here about another card with that name. It's probably a good idea to change it to "HA simple timer card" or have a note Github of a possible conflict with another card?
Aside from that. Thank you for creating such a useful card!

Yes, it could be helpful to rename the card and add a note on GitHub.

Initially, I planned to release both an integration and a companion card, but for ease of use, I bundled them together under a single installation.

About a month after I added this to HACS, someone else added his Simple Timer Card. I’m not sure why it was approved with that specific name, as it clearly creates some confusion.

Thank you for your feedback.
