I am new to the forum and am hoping someone can help me with next steps. I deployed my SkyWeather about 2 weeks ago after a (really) slow build. Everything was going well and the unit passed all the tests. About 4 days ago after a really intense rain, the unit stopped working. At first I believed it was the reboot/clean-up job running so I logged into the device to reboot it. When it rebooted and I went to start the program I receive the following:

Based on my reading in this forum prior to posting I believe that my PiWeather card is bad, but how exactly can I confirm this (in my mind I imagine the fault could also lie with the Pi2Grover card)?
Below are the results of the first 2 tests in the guide which are both seeming to error:

I am pretty crushed that this wonderful project is now reduced to lights and am hoping someone can either spot the error or advise me what I can do to resolve this.

Oh my. I **think** that something has gotten wet inside. Did you look inside the box?
Run the tests again and post the results. Unplug the AM2315 and see if that makes any difference.

There were a couple of small water marks on the pi2grover, I cleaned these with an iso qtip.
When you say remove AM2315 I took that to mean I should unplug from both pi2grover as well as grover 6 port hub (so they system has no path to this sensor).
Below are the results of my re-test:

Based on my results above I believe it is the Pi2Grover board that failed, is there any other way to confirm this? Specifically can I confirm that it was just the pi2grover board and not also the PiWeather?
Thanks,
Dan

Hmm. yes unplug the AM2315 from the I2C bus and retest. That can take the Mux down if it fails in the right way.
It is unlikely that the Pi2Grover has failed. It's really a simple board.
I think the PiWeather board has died. Having the mux out causes a lot of false negatives in the tests.

To update this case I purchased a new pi2grover and piweather card. I will replace these one at a time and revert.

Dan,
Please let us know what you found out.
