Hi,

I was thinking deeper and now it seems possible.

E.g. a TINY12 read out the SHT11 permanently and if a 1-wire reset was detected it was prepared to compare the first bit and stay in an endless loop until the low level was detected and so on for every bit.
So no time was wasted to enter the interrupt handler and to decide, what to do.

And a timer can generate a time out to return to read out the SHT11, if no bit was transferred within 10msec.

A valid serial number can be generated with a serial number chip connected to the TINY12.


Furthermore such a TINY12 can also be used as 1-wire-repeater on using longer lines.
