Re: H&M 7000 DCC by Bluetooth

They could have built in a bluetooth feedback circuit into the PSU and made a complete system. At £60 that would not have been beyond reasonable to expect. This is ill thought out on all aspects of system safety and functionality. A current measuring facility would meet both requirements. In your ca...

Re: H&M 7000 DCC by Bluetooth

Hornby just proved my point, with that message in red.
Also, why should users be tied to Hornby PSUs at £60 each ?
More concerning is, users will have no idea of current load on any layout - just a poorly designed concept !

I do look forward to seeing the App when it appears !

Re: H&M 7000 DCC by Bluetooth

Please, before giving comments like 'cods-wallop' have the kindness to understand my point. An over the air system can control an external device against short or overload. I know because I made one that does ! It is a case of the BT device sending back messages to the App i.e load current When a se...

Re: H&M 7000 DCC by Bluetooth

Most DCC Controllers have (or should have) fast detection of short circuit to protect layout and locos. This system does not. To rely on the PSU is not sufficient. There is no 'Load sense' either i.e. means of monitoring current which is definitely required (or at least an advantage) in running a la...

Re: H&M 7000 DCC by Bluetooth

What is the short circuit or overload controls on this system ? Does it measure load current with feedback to the App to allow control over the number of locos running on a layout ?

Have Hornby developed a load sense module ?
