Hi This is in accordance with owfs man pages: An owfs write 1 in the PIO will closed the internal switch: that means connected PIO pin to ground= 0V The owfs 2408 man page about the sensed propertie says: Logic level at the PIO pin. 0 = ground. 1 = high (~2.4V - 5V ).
But the owfs 2408 man page about the sensed propertie also says: Really makes sense only if the PIO state is set to zero (off), else will read zero. I'm not sure to really understand this statement. I think it's when you use the PIO as an input. Can anybody clarify? By the way your hobby board 8 Channel I/O board has relays with normally open and normally closed contacts so you can reverse again according to your needs. -- Guy Marc MERLIN a écrit : > I'd like to add some info about the moisture sensor > and the hobby board 8 Channel I/O (8 Relay Version) (8CIO8-R1-A or > 8CIO4-R1-A). > Can someone give me access to the pages? > > > By the way, the 8 channel I/O from hobby boards works fine with owfs > from the intial testing I did. > http://www.hobby-boards.com/catalog/product_info.php?cPath=24&products_id=1554 > > The only weird thing on the I/O board is that I get: > gargamel:/etc/owfs/bus3/aux/29.E73E06000000# cat sensed.ALL > 1,1,1,1,1,1,1,1 > when the input and relay is 0 > > gargamel:/etc/owfs/bus3/aux/29.E73E06000000# echo 1 > PIO.3 > gargamel:/etc/owfs/bus3/aux/29.E73E06000000# cat sensed.ALL > 1,1,1,0,1,1,1,1 > > Any idea why owfs shows the opposite value? > > Marc ------------------------------------------------------------------------------ _______________________________________________ Owfs-developers mailing list Owfs-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/owfs-developers
