Remote Screen Access with Pi zero

Hello! I am looking to create a project that acts as like a message box. Whereas I open a box and a screen is inside displaying what I have put onto it wirelessly from say across the world. Could someone please guide me to what else I may need as im not sure what I really need! I believe these are the main components I will need : Raspberry Pi Zero W https://www.amazon.co.uk/OSOYOO-Monitor-Raspberry-480x320-Interface/dp/B085TC5YMR/ref=sr_1_3?keywords=raspberry%2Bpi%2Bzero%2Bscreen&qid=1701016437&sr=8-3&th=1 ----------------------------------- LED that blinks when a new message is sent to the screen and stops blinking once the box is opened (detecting motion) PIR Motion Sensor Module Diffused 3mm LED Pack - 5 LEDs each in 5 Colors - 25 Pack Mini Breadboard - White ----------------------------------- I have basic coding skills in HTML and Python and technical skills but nothing with Pis and the sort. Many thanks, Ryan.

I will also need a suitable PSU

this is certainly not a small project

I can not help you I don't think

I mean I probs can help you with little things like the led and motion sensor

but sending stuff across the world, unless you use discord which is my usual tactic for that, well I have no clue

All i want is the ability to send and display a line of text or an image

and have it display onto an lcd

i know how to send a message to a private disc server

thats how i get imformation from my pi to me

i just use discord webhooks

can that process be reversed, discord to the pi?

not easily

There is public "free" MQTT brokers that could be used in this case. And the MQTT broker is working as a message box where someone can send or receive messages from. And there is libraries for most OS/languages.

And as for a project, just divide it into small pieces and get them working apart and then start to combine them into your final project. This is also the tactic you can use to eat a elephant 😉

now that I think about it I have seen some python modules like this

https://pypi.org/project/messages/ this looks good, get it to send emails to each one, this way you can control and see them from anywhere your logged in and you can send from pi to pi

it comes with a receive function so you can easily set it up to show it on a small screen or whatever your planning to do. all the pi would need is internet on both ends, in terms of the pi that's recieving you could just use a data attachment for like $15

I was thinking about creating a web page that the Pi0 Listens from and downloads data on that page that is sent/uploaded from my phone

SOmething with this?

What happens if device is not in my network and at my fiancés?

Like maybe it listens onto a website that is ran externally?

oh nvm I can use a public mqtt broker

Mosquitto?

But then the issue arrises downloading other peoples things on the broker ... dont want some random images showing lol

And yes, mosquitto is a common MQTT broker, I have used it for 14 years now.
