H&M 7000 DCC by Bluetooth

[Billc]

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 car analogy, it is like a reversing system without a camera !
You drive blind and that is what users are doing with HM7000

The vast majority of cars don't have reversing cameras - drivers look over their shoulders when going backwards rather than driving blind.

With HM7K the recommendation, which is absolutely clear in the instructions, is to use a Hornby designated PSU or an existing DCC system to supply power - all of which have the necessary protections built in. Or you could ignore the advice and take your chances. It's the user's decision and their responsibility should a non-recommended PSU be used and result in damage.

Hornby should be applauded for developing a system that has the potential to take DCC to a new and affordable level, not endlessly criticised.
