Susan: Do you have a Davis system? The reason I ask is that, from my reading of the comments over the last few years, this 'argument' between the RPi starting up and the weather station hardware may be limited to the Davis systems with their logging interface. Would you be willing to share your coding/scripts/etc with the rest of us? Although I have added an RTC and a UPS, I wish that my system was robust enough to reliably deal with power interruptions without these additions. (The RTC and UPS cost more than the RPi!)
