Sensor Update Fails with IndexError

[ABeard89]

I set up my feeding times using Home Assistant Automations because I need finer control over the feeding times than the PetSafe app lets me (it only lets me set feeding times on 15-minute increments (XX:00, XX:15, XX:30, and XX:45)).

Because I am using Automations for meal times, I don't have any meal times set up in the PetSafe app. The Integration seems to make the assumption that at least one meal time will be configured, which is flooding my log file with IndexError messages.
