I was looking through my timeline and I have noticed that every day, I have had an automatic test signal received message at 9:37pm. Except for yesterday. Yesterday I had no messages about automatic test signals at all. What does this mean? Does it mean that my base wasn't sent a test signal, or does it mean that one was sent and that my base didn't receive it? I see no errors and the only message I see for yesterday was when I disarmed my alarm when I got up.
Thanks
