[Owfs-developers] Temperature-Sensors show mixed power states

Hello to all owfs-developers, First of all I am very pleased with the all the work you must have put in, to bring owfs to such a mature development state. I am using owfs, 1-wire, mblogic and self-written software for the heating system of my house. There is a wood-burning oven, that heats water,

Hello Paul, is there a way I can test the "Skip ROM" option you mention? I found this in the DS18B20 Datasheet on page 5: In some situations the bus master may not know whether the DS18B20s on the bus are parasite powered or powered by external supplies. The master

Re: [Owfs-developers] Temperature-Sensors show mixed power states

Thanks Bill, yes, I knew about the power supply, but it was unclear to me how to determine the overall power-consumption of all the slaves on the bus. I found the maximum current for a DS18B20 being active is 1.5mA - with 15 (at the moment) this would be 22.5mA. So far so good. But for the DS2
