No I’am sorry, I havn’t made any statistic.
But the GHI Onewire Module is spimply a pullup of 4.7k on the dataline.
So if you have long wires you have more capacity then on short ones. So if you have a large network you need a strong pulldown and pullup, so that the edges can change fast.
In my setup I have 11 ds18b20 sensors, the length of the wires differ from 1 meter to 50meters.
Without the master I had problem’s, as you descriped the FindAllDevices Method doesn’t worked. Sometimes I got the wrong data, crc error and so on.
With the DS2484 ow master, it worked without any problem. Also I hadn’t to add a 100-150ohm resistance in series of each sensor.
