Final update. It seems you can change the ADC configuration (by hand, not cut and paste!) From 08 8C 08 8C 08 8C 08 8C To 00 0D 00 0D 00 0D 00 0D and it works. Sorry to inflict a learning experience on you! All the best Brian

Eric: I think I have partially solved my problem. It seems that there is some kind of initalisation sequence that onewireviewer does not do for the DS2450. Until I run simpleweather, strange voltages show. Afterwards, OWV shows the correct voltages. Bug in OWV? Thanks for reading all this...

one last thing: is there a problem with onewirelister? I have checked the voltages at the pins of the ds2450 and the multimeter shows 5v when the switches are open (as it should) but OOL displays 0, 2.5 when OOL displays 2.5 and 0.00 when OOL displays 0.03. This is weird! Brian

Correction to last: OneWireLister reports 0v when no switches are closed (should be 5v) 2.4 when a switch goes to ground and 0.03 when it goes through the resistor to ground. Thanks Brian

Hmm. That was big of them, especially since they don't seem to have squat on their web site now! Re: the epoxy blob, it looks like it is only covering jumpers anyway. see deanostoybox DOT com - weather - hardware - AAGv3compID DOT html where 'hyphen' = slash (Can't post links yet) I don't...

Thanks Eric, well, if nothing else, I'd like to know if I'm wasting my time trying to repair it, and I'd also like to know what the real schematic is. I guess the one in Tim's book is based on the AAG schematic that used to be on their website when it was useful, before it became the...

Hi, lightning killed my WS-1 and I've replaced all the visible ICs. The only schematics that I have found are either the old irrelevant V1 from "sensors" or the one in Tim's Weather Toys book. However, neither account for the big black epoxy blob on the board. Since I don't seem to be getting...
