Gen 2 Motion Sensors Randomly Stop Working

Good to know I'm not the only one! I couldn't find any similar complaints online. The first time it happened, I think it was not long after a system update, so I thought it may have been related to the update. I don't think there was any recent updates this time. I have had a few power outages recently, so maybe that could be related. I am going to try to remember to check the motion sensors the next time the power goes out.

All three of my sensors have stopped detecting motion again this morning, but if I put the system in test mode and press the test button on each device they report in. They just don’t detect any motion. I can walk up to the sensor and cover it with my hand, no detection. 

Simplisafe support contacted me off the back of this post (which was very good customer service).  They spent half an hour checking the system over and doing some tests with me, but couldn't find the root cause.  I was able to demonstrate the problem to them, as the sensors weren't working when they called. 

They've now sent me three replacement motion sensors and will monitor the situation.

Pleased with the support given so far.

@mistersimes How did you test to know that the Gen2 motion sensor was not working at that particular time?

I always arm the alarm at night, so when I come downstairs in the morning the hallway sensor normally detects me and starts the disarm countdown.  When the sensors 'crash' it doesn't detect me, that's how I can tell there's a problem.  I usually then put the system in test mode and do a walk test and find that all the sensors have stopped detecting motion.

@mistersimes​ SimpliSafe contacted me as well. Glad to know they are working on it! I also have a glass break sensor and don't really have a way to know if it is being impacted by the same issue since I'm not going around breaking glass on a regular basis, so I went ahead and took the batteries out of that sensor and put them back in.
