Erratic behaviour of HC2 before crashing. Cause?

[FrancoisRB 0]

Good evening,

My Fibaro Home Center 2 keeps crashing. Tried a lot of things already, like recovery and putting back the backup. Recovery and completely reinstalling the setup (excluding and including all devices) helped for a month or two. Then coming home from a short vacation, the HC2 had crashed again.

I notices that the Aeon Multisensors kept sending updates on humidity, lux, etc all the time. So I switched those updates off, only using the breached/safe status updates. Still the HC2 kept on crashing.

Updating from 4.130 to 4.140 did not help.

Then I did another recovery and putting back the last 1.40 backup. Now I monitored the CPU activity.

Figure 1: Without any reason, the CPU starts to behave very erratic at 17:15.

Figure 2: During that time no updates are recorded on the laptop.

But somehow the HC2 survived and kept on going.

Figure 3: Another spike at 19:10

Figure 4: But the HC2 keeps performing normally

Figure 5: At 19.35, again this erratic CPU behaviour, but now the HC2 crashes while we were watching Netflix. So no activity/movement in the house.

 

Can anybody explain what is going on? What is causing these strange CPU activities?

Are these CPU activities linked to the crashing of the HC2?

And what can be done to prevent the HC from crashing over and over again?

 

I appreciate any comment.

 

Setup:

HC2

Aeon Multisensors 6 (5x, using adapters, not batteries)

Fibaro Dimmer 2 ( 4x)

Fibaro socket switch (1X)
