Looks like we have a competitor of iRidium mobile software for iPhone/iPad/iPod Touch. TPControl also allows to use Apple devices as full-featured touchscreen control panel for AMX home automation systems. It supports TP4 file natively and offers all functions of original control panel via WiFi or 3G connection. Additionally TPControl is authorized product partner of AMX.
I didn’t find the price of the TPControl software because as I understand it’s available via dealers only. The demo version of the software can be downloaded from AppStore and server part – from the producer site.
The server part is a disadvantage of TPControl comparing it with iRidium mobile. Because iRidium doesn’t need anything on the server side. Moreover, iRidium can be adjusted to use it with other IP-based home automation and entertainment systems.
