I have 2 Pixies and both are on smart schedule. However, one has been acting up and showing a yellow triangle without any explanation for every other run.

Example:

Pixie 1 - Nov 24 - Good run

Pixie 2 - Nov 24 - Good run

Pixie 1 - Nov 26 - BAD run - yellow triangle

Pixie 2 - Nov 26 - Good run

Pixie 1 - Nov 28 - Good run

Pixie 2 - Nov 28 - Good run

Pixie 1 - Nov 30 - BAD run - yellow triangle

Pixie 2 - Nov 30 - Good run

Why would this happen????  I have cameras and PIXIE 1 DID NOT RUN on 26th and 28th.

Thanks.
