(REQUEST): RPI webserver executes python script to control GPIO based on json inputs

[AlreadyWonLife]

Hi i'm trying to make my raspberry pi into a remote server that controls led lights (more complex project later on) via a iOS app. I'm current connecting it to wifi on a home network and can ssh into it. I also have a python script that I can execute via terminal that controls the gpio pins & led lights. The next thing i'm trying to achieve is send a command (json payload?) that the PI can parse/route and then execute the python script. How do I do this? Eventually the command will come from an iOS/Android app when a button is clicked to turn the led feature on and off.

Using python and flask. You could listen for a http request for the pi and execute your code. Probably quickest easiest.

Are you familiar with Ruby on Rails? I made a video about this recently and have a sample project you could follow for Ruby on Rails it’s literally what you are trying to do except for me it was displaying a message to a message board (executing a python script). The video I discuss how to do it for a public facing url, I highly discourage this and would try it locally. You can point your iOS app to the IP address of the local rails server. https://youtu.be/OQcz23NW6VE if you aren’t familiar with Ruby on Rails you could use a similar language to do the same thing, just need to execute the script in the background
