Erroneous Messages? (False fire alarm and keypad )

So our Simplisafe 2.0 system at our cabin did 2 odd things today.  First the smoke alarm went off.  I  checked the temperature remotely of our thermostat, and the Simplsiafe temp sensor, and both were normal.  had a neighbor drive over and check things out, all good.  So seems like a false alarm in an empty house.  First time that has happened.   Humidity is high up there but it's been higher this summer, never had a problem.

Then, a few moments ago, I  got a message that the alarm had been Armed to away mode using the keypad.  Problem is again there is no one home, and the system (correctly) shows that it was never disarmed from when I  armed it a few days ago when I  was there.  The test signals have been coming each day.   The house did lose power for an hours or so yesterday evening for about an hour, I  assume when it came back it didn't short the base station or anything (it did get a test signal since then and it's communicating).

New Firmware was downloaded last week.

any ideas?  


Thanks
