I have the code from Nathan Chantrell running on a Nano and a ATTiny84A-PU with RFM12 without problems: https://nathan.chantrell.net/tinytx-wireless-sensor/
But i'm looking for a RFM69 solution.
I found the lowpowerlab.com stuff/library put not one single example with DS18B20
and I can't figure out how to do it.
For JeeLib there is allot of examples out there but RFM69 is not really supported.
