The browser orders owhttpd to do exactly that. What you see isn't one conversion but a series of conversions of which some failed because of a Power-On-Reset during conversion (that's the 85°C reading) and some failed not.
Check your cabling. Also check if powering the chip helps. Kind regards Jan _______________________________________________ Owfs-developers mailing list Owfs-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/owfs-developers
