Then I agree ;)
The DS2483 has much more possibilities like the DS2480/2490 which arent
used in owfs right now like timing on speed, slewrate etc; I'll ge mine
ready next week and then be with you

This means, that 1-wire bus is powered by 3.3V, which can slow down
communication on long lines.

Hi,
This is using the 3v3 from the RPi, I've not got the required parts to do level
conversion but I have a level convertor on order.
Here's the uncached reading again

Hi Stuart,
Do you power DS2482-100 by 3.3V or 5V?
Also it is better to determinate what bus you are reading e.g.
/uncached/bus.0/28.52DE9900/temperature
