Darren, many thanks for your answer. We have another questions... (our English is not good, we know) 1) The Home Gate demo software is very similar to C-Touch one, is'nt it? These softwares are only for control purpose? 2) If we install a C-Touch, it will be necessary to install Hme Gate too or not? 3) We intend to replace Home Minder and program security with C-Touch or Home Gate. Is it possible to program special security functions such as entry delay time or exit delay time? We try to have only C-Bus Units and we think it si possible. 4) Our customer want to have Internet Access so we are thinking alternatives. Do you sugesst another? Do you know if someone has done anything like this?
