Weather Station Back Online

I gave the entire 1-Wire network a complete going-over. RF is a big problem around here, since there's a 50KW AM transmitter within a mile of here. The new 1-Wire adapter is optically isolated from the computer's USB circuitry, and the adapter power supply is isolated from the house wiring, so presumably, there's no RF path to ground, and thus no current can flow.

However, the system had been working reliably for several years, before it began its downward slide. Maybe a lightning strike damaged the old 1-Wire adapter. I'll do some diagnostics on it when I get a chance.
