The DS18B20 library works with mesh devices. That's what I recommend.
However, it's not 100% reliable. You'll probably have to do more retries than you would on the other devices. I think there's a timing/interrupt issue in the OneWire library that causes it to drop bits occasionally, especially with multi-drop.
The Particle OneWire library version 2.0.3 has mesh device support. Any other library that depends on that version instead of an earlier version should at least compile on the mesh devices.
