## What is VBusTouch free?

VBusTouch is a software especially designed for the Apple iPhone and iPod touch. It displays both live data and progression charts of the solar system at any place in the world, provided that the system is run by a RESOL controller equipped with a VBus® interface and a 
datalogger connected to the Internet via LAN. 

If the iPhone or the iPod touch are in portrait orientation, a hydraulic scheme and live data of the system are displayed. As soon as the device is turned into landscape orientation, the integrated accelerometer switches to the display of a progression chart.

## Key features

- Live data display
- Progression charts

### 4/5 — Great DL2 monitor

*2012-04-27*

App works great in F and lets me know exactly what my solar system is up to from anywhere.  Daily graph is interesting, wish it showed more days.

### 1/5 — Solar User

*2011-10-25*

This app stinks. The iPad version works better but isn't great either. I wish these guys would do a better job with this.  Another problem not already mentioned is you can't view temps in F... Only C, now matter how you set the conversion button in the config screen.  All around a poor effort.  Come on Guys.

### 2/5 — Needs work

*2011-06-11*

The idea is good. It is buggy (can't edit, can't cancel (which means remove/reinstall)) In other words it is good as any other Resol product. These guys just want to claim a feature set. 

Actually delivering the features is too much of a bother.

### 3/5 — Very useful but....

*2011-05-13, version 1.1*

This is brilliant but only 3 stars as I have East / West panels and don't seem to be able to get that format to work on the app! Please Resol can we have an update with more features and more flexible graphing eg more days etc.

### 1/5 — Even Caleffi can't figure it out.

*2011-05-11*

I have spent to much time with no result. It is way to hard with no technical support. One other system that I know about does work but only in their Wi Fi area.

### 5/5 — IPhone VBUS

*2009-12-03, version 0*

Excelent feature. Good for sales reps.

### 4/5 — Neat engineering app

*2009-11-09*

Awesome remote monitoring and data acquisition app. First of it's kind..
