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.

Weather Station Going Dark For a Few Days

I'm going to take my weather station offline for a few days for much needed repairs and improvements. My humidity sensor has been flaky for the last several weeks, and my attempts to fix it have been unsuccessful. So I'm going to take the whole thing down, and replace all of the RJ-11 and RJ-45 connectors, rearrange the wiring layout, and clean and oil the wind sensors. I'll probably bring the sensors back online one at a time, as I dial in each one before adding the next.
