does not go 7

I wanted a lamp with the HE842 Wall Switch (who has already noticed as another reviewer a button is) switch for the lamp I provided the Mini-built-in switch HE875. It was not hinzukriegen that both talk to each other, while I have kept strictly to the instructions (connectors properly connected learning mode in HE875 activated etc.). I have been doing even the HE842 held right next to the HE875 (spark gap no 20 cm), there was no metal shield between the button cell in the HE842 is loaded. Nix.

Here is the general description for the Home Easy system, we say, suboptimal. From her I rhyme together to me that this combination should work. But certainly is not. Maybe missing any component (remote control)? Anyway, I've had enough of the scrap. Actually, a star is too much for it.

Addendum:
I absolutely recommend some extra money for the Inter Techno system lie. The combination of mounting radio switch CMR-1000 and YWT-8500 Radio wall transmitter worked immediately, also the range is also quite remarkable. However, the radio wall transmitter also has a much more powerful battery than just a button cell
