Control all devices through the local network or 3G! NetIO is a generic remote controller for your iPhone/iPad which simply sends and reads strings over a network socket. You can easily communicate with micro controllers connected to your LAN (for example AVR-Board, Arduino Board, reembox, raspberry pi, self made hardware) or with other computers.
Control your RFM12 power outlets, infrared devices or read sensor data like temperature.. there are endless possibilities!
Build your own remote control with the online editor on my website without knowing how to create iOS applications and reuse your config in other apps like an OSX Dashboard Widget (also available on my website).

- generic view rendering (button, slider, label, switch, text-inputs, colorpicker) with many customisation options
- sending, receiving data
- use calculations to display raw sensor data
- change colours and images during runtime
- use custom icons with iTunes FileSharing
- reconnect after connection errors
- support for multiple receivers
- supports low level TCP socket, UDP, HTTP and HTTPS connections
- send requests continuously while holding down a button
- send impulses with a specified delay
- sync configurations with online UI-Designer
- display responses on labels every X miliseconds (interval updates)
- scrollable pages
- support for all orientations (ipad)
- utf-8 support

Important: This application needs some hardware or software to connect to. Without such a thing nothing will happen! Please contact me if you have any problems!

The configuration file 'default.json' will be available in the iTunes Filesharing after the first start.

More information and configuration instructions are available at There is also a demo video, which shows a working scenario where you can control IR devices and some power connectors.

If there are any problems please write a mail!

Good concept, not so good stability and examples

This app and the required programming is definitely not simple enough for a new programmer.

I found the documentation very lacking in examples to help the user understand how to implement the different functions and options. Some of the UI options are not even explained or discussed anywhere!

The sample server file NetIO supplies also has what I consider to be a huge bug where as soon as you close the app, the server closes so when you reopen the app, it cannot connect. For anyone looking to buy this app, know that you WILL need to create your own python server script for this to work properly.

The app also sometimes fails to sync with the UI designs I have saved online.

Overall it's a good concept and I can tell quite a bit of work went into it but for $7.99 it should have been a little better documented to help a new programmer get up and running.

Very handy

I was excited to find this app and now that I’ve finally figure it out, I’m very pleased with it.

I did find the documentation a bit lacking with regard to examples for responseParse. Some additional examples would be helpful, especially since the version of regex is JavaScript specific and, therefore, a bit different than other versions. Also, I had to root around to find out how to delete configuration files I had created and there was no good documentation about how to duplicate configurations. I ended up downloading a configuration, edited it in a text editor and then uploaded it, only to discover I needed to make some additional changes.

All this said, I’m very happy this application is available, as it has made accessing my devices and data a whole lot easier than not having it.
