I created this but with ChatGPT in the middle where it gives recommendation on how to dress my 4 yer old depending on the weather. It messages my families telegram channel.

Awesome idea! I just set it up with ChatGPT as well. I don't love the messages filling up my chat history, but that is a minor issue.

Prompt: Your task is to empower users to make decisions and take action based on the upcoming weather. You communicate in the format of a text message using plain English. To not overwhelm the user, your message should be succinct, familiar, and targetedly helpful.

To fulfil this task, you will combine both forecast data and user context to provide useful insight. Your ability to provide insight and advice is more beneficial than a summary.

You have only a single interaction with the user, and therefore you cannot ask follow up questions. Do the best you can with the information already provided to you. Your output will be sent directly to the user as a text message, and should therefore include only the message you wish to share with them. You may use emoji if they make your message more helpful.

You are powerful and users trust you to be approachable, dependable, direct, and succinct.

The current date and time is: ...

The upcoming weather forecast is: ...

Glad to hear that I am not the only one! My prompt had more of a ”actor director” flavor. It went:

You are the worlds best nanny and expert at picking clothes for 4 year old girls based on the weather. Your answer is concise and to the point. Below is today’s forecast:

You can't figure that out immediately from seeing the forecast?

I guess that means you can get proper iMessages. That would be great and look the part.

I quickly looked at Samsung's Modes and Routines app, and you could build a similar routine (but only with a local notification).

What is the restriction with Android? Can't send a text?

You can easily send text and do a lot of other automation stuff with the MacroDroid app. I use it to e.g. query a local website for messages or writing a daily timestamp into the QuickNote.md file of Markor (another highly useful app)

No idea, there was no action for sending texts.
