The OurWeather system has been installed and works fine for a while. The firmware seems to be the most recent (checked via OurWeatherAdmin). The system reports to Weather Underground.
After a while, some of the numbers stop making sense. Dates, temperatures and humidity are wrong. Power cycling fixes the problem for and indeterminate amount of time. Here are some examples:
The time has been reported as "85/165/2009 37:165:"
The Outdoor Humidity as "NaN %"
The Indoor Temperature as "-231.16F"
The Barometric Pressure as "40.29 in"
Suspecting the temperature/humidity sensor, I purchased and installed a new one, with similar results.

Holy cow!
Does the clock ever come back?
I would guess on of the I2C devices is starting to fail. Try unplugging the clock first. That's what I would suspect first. I've seen a couple of those fail.
Report back and let us know what is going on.

When I remove the clock, the time comes up wrong as above. I've just done that, and will monitor whether any of the other data get's corrupted with the clock gone.
In the past, the correct time consistently returns (without other intervention) when power-cycling the hardware.

I'm thinking that it is the clock screwing around with the I2C. Best guess.

BTW, when corruption occurs does the white light on the WeatherPlus board stay on all the time?

A few hours later and the system is reporting an indoor temperature of -231.16 F, and outdoor Humidity of NaN%. The time is still unusual (as expected since there is no clock in the system. And the barometric pressure is 40.29 in.

In response to an earlier query, the white light on the board flashes intermittently about once a second with a burst of flashes about every 10 seconds.

Put the clock back in and remove the AM2315. Go through each I2C device and see which one is hosing the bus.
Because the white light doesn't freeze, I'm thinking that the WeatherPlus board is OK and it is one of the other devices.
Sorry for the hassle, but this is the way we can get to an answer quickly, I think.

In the testing I've been doing, it is looking like both temp/humidity sensors have a problems. Remember, I had a problem with the original temp/humidity sensor that came in the kit, so I bought another from SwitchDoc. The second one is the one I used for the outside.
With the clock in place, but no display and no temperature/humidity sensor, no problem was observed in over 12 hours.
Adding the original sensor inside the house, but with no display, the system time remains good, other system readings are fine, but the "Outdoor Humidity" goes to "NaN" after a few hours. This test has been running for over 12 hours.
It would be strange if both temperature/humidity sensors were broken.

Yes, we are talking about AM2315 Temp/Humidity sensor.
I have not extended the cable any. To do this, I have the weather board set up high on the wall inside, near the hole that goes up to the outside instruments. The OLED display does still work, but I have detached it since I can not see it.
I resist the solution that continuously power cycles the AM2315. I assume that most sensors work properly with the need to power cycle.
How do I get replacements for the broken sensors?

Last post should say "I assume that most sensors work properly WITHOUT the need to power cycle."

I think it is very unlikely that both AM2315's are bad. I'll issue an RMA for it, but we will test them and see if they are good, and if so, we will send those back. If they are bad, we will replace them.
There is probably something else going on here.
Before you send them back, make sure you are running the latest version of OurWeather V031. There were fixes for the AM2315 drivers in some of the newer versions.

I agree that it seems unlikely that both AM2315's are bad, but I've tried everything else you've suggested. Note that one of the sensors is worse than the other. One of the two only ends up with missing data for the humidity. The other one also corrupts the clock and other data in the system.
There is nothing I was supposed to do regarding I2c pull-up resistors, was there? I didn't see anything about that in the instructions.
I checked the software version just now and it is 031.
Absent any other epiphany, I'll send the sensors back tomorrow.

Sensors have arrived at SwitchDoc, according to tracking. Let me know what you find,
