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!

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.

Powerful App for an Arduino

If you own an Arduino that has an ethernet connection than this is a must have app!! Completely customizable, from buttons to backgrounds. This app flawlessly transfers data from iphone to arduino and back. I have used to read and set a temperature from my iphone and remotely turn pins on and off. There is a little bit of a learning curve when getting started, but if you have any knowledge of programming than you will have no problem.
