Switching from Wire.h (Uno/Leonardo) to TinyWireM.h (ATTINY85 or digispark)

Thanks for the reply.

So far I am testing on a digispark-clone (URL see later) or on a "naked" ATTINY85 (flashed with an Uno).
The digispark-clone runs with 16.5MHz (default) and the ATTINY with 8MHz (thanks for this hint).

The library was loaded via Arduino-IDE:
