Simple Mailbox notifier ( 2 sensors + optional camera )

Configuration Blueprints
1

Here the blueprint, generated with Gpt5.0… because i know noooothing about code.

Quite simple for european mailbox:
1 sensor for the mailbox fence
1 sensor for the latch
notifier via the companion app, working well.

Using Gpt to generate a script : nightmare !
I have to say it’s very limited and hallucinating on code a lot…
this is the 10th generation, with trial and error.

The other thing it didn’t succeed doing it was multiple selection for mobile to notify.

  • what do you think about the code quality ?
  • anybody could correct/add the multiple mobile choice so i can post it for the others ?

Hello Adefx,

Thanks for contributing to the community with a new Blueprint.
I have a suggestion for you. Many people who are not familiar with directory structures will have problems installing this without the Home Assistant MY tools.
Adding a MY link for this Blueprint to your top post would help them a lot.
Here is the link to make that.

If it doesn’t work the way it’s supposed to, then the quality is 0/10… your time would have been better spent reading the docs.

None of your Entity selectors are correct. You can read about how they should be configured to filter by domain in HA Docs - Selectors - Entity

You can find the details for Device selectors on the same page… just a little further down. Once you’ve found the Device section, look for the word “multiple”.

If you want to be able to select multiple devices for the notification, you will need to place the action in a Repeat for Each action.

Ok thanks,
The script is doing what i want, but as i told, i know nothing about coding and was aware to know if a chat gpt has done it right.
Regarding your gentle answer the coding capability of GPT aren’t the best…
Going to improve my coding skills reading TFM.

Thanks

Is this ChatGPT hallucinating again/still? Sadly the time spent futzing could have been used to read and understand the vendor documentation, which is accurate and up to date, and produced a far better outcome, as well a stepping board to continue your automation goals.
