I need some useful information about running a local web server in a Raspberry Pi and the best embedded system that can handle my device.

What do I mean?

Well I've created a website using django + redis + celery + postgresql

So what I want to do with this website is to Turn on/off LED lamp using a BreadBoard. This is done by celery ... actually there is a task (celery-beat-schedule) that should turn off/on some specific LED lamps.

And the django is the firmware that creates those tasks and controls my device

For example:

Imagine I have a task that represent the main job of the device (turning on/of) a I can create and run this tasks using django-celery-beat.


The main question is how can I run this in a embedded system like Raspberry Pi. Actually what are the best hardware like CPU RAM this website can run on that and does not crash?

For example, is Raspberry Pi zero w suitable for running this web server and setup? And there is no limit to the implementation?

Of course, let me say this too. I don't want to spend too much otherwise I think the Raspberry Pi 4 is the best.

Updated: Also the OS is linux (Raspbian OS) as you already know.

    You are asking for opinions which is off topic.

    How would we know that you are using Raspberry Pi OS (different from Raspian)? There are several Linux distributions that work on the pi.

    you can use an Arduino UNO for this ... any Raspberry Pi is way more powerful than UNO

    Raspbian is MEANINGLESS - it could be any of 5 families of OS spanning 10 years. Even Raspberry Pi OS is ambiguous - at last count there are 8 and there are significant differences between Buster & Bullseye.

    What are you using redis and postgres for in a "simple website for controlling a led"?

All Pi's should work for this simple set-up.

Of course, there are limits to the implementation. But for a simple set-up as yours, you are far below the limits of the humble Zero W.

  • Except for the Pico, which can probably still do it, but doesn't run Linux so you'll have a harder time.

I hosted an Nginx server on a Pi 4 with 4 Gb of memory for a personal site, it worked well for local connections. Hosting a site to control a lamp should be within the capabilities of all Pi's, although Django seems a bit overkill for this. Perhaps try Flask.
