Anyway, I thought to myself that it was easy. However, I have only made the mistake, the cost of scrap Home Easy (psc = 1 and PSC = 1) to buy. Did not go, I really (swapped battery etc.) tried everything, and I'm not completely stupid (physicist).
Then I bought ado this radio wall transmitter as switch + radio installation switch CMR-1000 for the lamp. Mounted, code both devices set to the same, went. Ten minutes later it was done. Super!
