What? Yes, a WebServer!
There are some use cases where you simply do not want to run another device just to serve a few resources by http.
The app runs a WebServer locally on Homey. This WebServer is not reachable from Internet.
You can use it to host basically any resource you need in reach on your local network. Like a sound file used by another app. Or even a web page.
To get started, go into the app settings and start the integrated ftp server. Whilst the ftp server is running you can manage the content of your Homey WebServer with basically any ftp client.
This app provides a WebTrigger flowcard for LAN integrations. See the app's forum page for details.
Now you can not just host your own web panels and resources on Homey itself but also trigger flows by sending a HTTP GET request to the WebServer.
Warning and Disclaimer
Whilst you could basically make the Homey hosted WebServer public on the internet using port forwarding, I highly recommend not to do that. The app is not meant to serve tons of requests from random people.
Also, I am not responsible for the content you are hosting with it, nor for any possible harm one could do to your Homey by abusing it.
