Switch does not respond

[ThomasFTL]

I have the current Silvercrest switches in use.
https://www.lidl.de/p/silvercrest-funksteckdosen-set-mit-fernbedienung-5-3-teilig/p100366993
(indoor version)
An HS 2300-P is installed in the remote control. The circuit board was produced in January 2019.

The remote control is recognised with protocol 2, a decimal and a binary value (32-bit) and with a pulse frequency of approx. 700. This value fluctuates between 698 and 703.
The RAW values fluctuate with each transmission.
If the same button on the remote control is pressed repeatedly, 2 different values are output alternately. If you only press On and Off alternately, only the first value is sent.

If I send the binary value with this data, the switch does not react.
The transmitter is a DigiSpark with 16.5MHz (standard) and a simple transmitter with spiral antenna.
To detect a pulse frequency of approx. 700 on the receiver, I have to set the value in the transmitter setup to 670.
The same decimal and binary values are displayed as on the remote control. Only the RAW blocks differ greatly from those of the remote control.

Thanks for help

Thomas
