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.
Got your own Homey Dashboard written in html and javascript? Let it be served by home itself.

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.

Getting Started

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.

Step 1 - Getting Ready for File Uploads

First thing to do after installing is provide some content to be hosted.
To get files onto the Homey we need to start the ftp server of the app. For security reasons it is not running by default.
Open the settings of the app. It should look somewhat like this:

After the ftp server is started you should see the ftp address:

Step 2 - Connect The FTP Client

Upload your files. Am using FileZilla here as it has proven to work nicely.
Open FileZilla and connect using the hostname shown after ftp:// (or your Homey’s IP) for the Host setting. The default port is 5081 and for login you need to use anonymous authentication:

And connect.

Step 3 - Upload Files and Test

After uploading the files you can address them by using the http address shown on the app’s settings page.
Let us assume you just uploaded a giggle.mp3 file. The address would be: http://homey-YourHomeyId:5080/giggle.mp3

About Directories

You can create or upload directories as well. If you open a directory url in your browser instead of pointing to a dedicated file, the app will automatically look for an index.htm or index.html file. Other default index files are currently not supported.

Available Flowcards

Triggers

A WebTrigger was received

WebTriggers are basically WebHooks which are available, by this WebServer, on your local network only.

Arguements

  • ‘Respond to Trigger Name’ defines the name of the trigger to react to.

Tokens

The WebTrigger can carry up to 5 payloads which are made available as tokens to the flow being run. Each payload as 3 representations as follows:

  • ‘Trigger Data # (as text)’
  • ‘Trigger Data # (as number)’
  • ‘Trigger Data # (as boolean)’

In addition the trigger name is available in the flow as text value:

  • ‘Trigger Name’

Usage

The WebTriggers are basic HTTP GET requests sent to the WebServer.
URL Example: http://homey-YourHomeyId:5080/webTrigger?name=MyTrigger&data1=MyTriggerData
Please note that the URL parameters are case sensitive.
The parameter ‘name’ defines the trigger name. It is the name you enter as arguement in the flowcard. The ‘data’ (data, data1, data2, data3, data4, data5) parameters are optional. The parameter ‘data’ is just an alias for ‘data1’.

Frequently Asked Questions

Q: Can it host a local copy of homeydash.com?
A:: Yes. This has been tested successfully.

Q: Which FTP client should I use?
A:: Whilst it is supposed to work with any ftp client, some seem to cause problems. It has been tested successfully with FileZilla.

Q: WinSCP does not list the files on Homey?
A:: It seems like the protocol version WinSCP uses for FTP is not supported. I do not know why, yet.

Q: The URL shown on the app settings page is not working with Chromecast?
A:: I am not sure why a Chromecast device would not resolve it. But try using your Homey’s LAN IP instead of the host name. This has proven to work as well. Like http://192.168.2.55:5080/aDirectory/giggle.mp3

Q: My mp3 file is not playing when I cast it using the cast audio url card of the chromecast app.
A: This is a known issue. I do not know why Athom’s chromecast app behaves weirdly there. But it will work if you use the cast website card instead.

Q: The FTP Server allows anonymous access, isn’t that pretty insecure?
A:: I did that for ease of use. However, the ftp server is not started automatically. Simply restart the app and no one can access it anymore.

Q: Does it support https?
A: No. This is not planned to be supported either.

Q: Can I run php scripts and things like that?
A: No. The WebServer only serves static files (HTTP GET is handled only). If you need such fancy stuff you might as well consider running a full blown WebServer on your lan instead. However, starting with v1.2.2 you can send HTTP GET requests to the WebServer to trigger flows.

Works like a charm with FileZilla. Have also tested CuteFTP but could not connect with it.
Nice job, well done!

Question:
Install app and add 100MB of files to the micro web server.
Then delete app, what happens to the uploaded files?
Will they stay on the server or will they be deleted?

The files are stored in an app context specific filestore. So I would assume that this storage is wiped when you explicitly uninstall the app. Anything else could be considered as a bug by Athom I guess :smiley:

Tried this today. Works fine on Sonos via hostname and ip address. But doesn’t work on chromecast devices (smart clock, home mini and chromecast). Tried the hostname and ip address.
Error:

Hi @PaN13k,
What did you try exactly? Can elaborate a bit more on what you are trying to do? And which card raised this error?

I tried to cast a sound url:

Oha, you are right @PaN13k.
I used it successfully with my Home Mini but my flow is now broken as well. But it seems like this is more an issue with the Chromecast app or the Chromecast firmware there. The URL works properly still. Guess I will test this myself now and annoy Athom about it.

Exactly. The URL also works here. Either via de Sonos speakers or directly via de browser. Thanks in advance.

My situation could be completely different but this is an observation from my ONVIF app. I store the last motion event image in what I believe is an app context filestore (not the standard image area). If I remove the app and then reinstall it, the last image is still there. To make sure it is cleaned up, I delete the image in the device onDeleted() event and that seems to solve my problem.
Just food for thought and I’m not saying you are wrong. A bug by Athom, really? :wink:

Thanks to @PaN13k for bringing to attention that the cast audio url of Athom’s chromecast app is not working when passing in a Homey Micro WebServer URL. I don’t know why the chromcast app started to behave wierd there recently.
Anyone having this issue should replace the cast audio url card with the cast website card, giving the very same URL to the mp3. That will do the trick.

I have a problem with my FTP connection; I can log in but do not get a directory listing and cannot upload any files. I tried several FTP programs, with the following output:

dos ftp command:

I’ve been trying to find a solution but I’m running out of ideas. I would really appreciate any suggestion that you may have.

Hi @Chris_Peters,
have you tried using FileZilla, yet?
Also, can you please submit me a diagnostics report for the app so I can check on your logfile? In your Homey app go to More -> Apps -> Micro WebServer -> Little Gear (up right on Android) -> Submit Diagnostics report. Please include your forum name in the report message for reference.

Hi,

thanks for the quick reaction.

The FilleZilla log is at the bottom of my original message.

I have submitted the diagnostics report; the code is: 0fc322a7-37c5-41f2-a7ee-69594bab919d

Hi again @Chris_Peters,
I assume the 192.168.1.100 is the system you are trying to connect from?
The good news, the ftp server part seems run properly.
The bad news part)
The server says it is getting timeout error while trying to write the result back to the client. Do you have any special desktop firewall software in place maybe which could be interferring?

I have windows firewall, so that could be a problem. I just don’t know how to fix that

@Chris_Peters hmm am also using the buildin win firewall without issues though. I will have a closer look at it after work. Let me know if you find anything in the meantime.
