Domoticz

On my Domoticz v3.5877 system I have several FIBARO System FGK101 sensors. One of them quit working on the 26st of December, so Domoticz thinks. I did an exclude and later include of the FGK101 sensor, the device appears in the list. Also, the blue LED is flashing when I insert the battery in the device.

What is NOT working -and I hope anyone can help me- is: when I normally make or brake the contact, the LED flashes and the device signals to Domoticz. None of those two things happen with this device. I used the device with another magnet, no luck.

So the strange is: the battery must be OK, because including and excluding the device work! Only the main functions of the device (making and braking) don't work! Like in this picture, the LED works (blue). In my case, nothing happens when I make or brake the contact.

Ps. I already did a reset with the procedure described at http://manuals.fibaro.com/door-window-sensor/ .

I also have issues with my Fibaro FKG101 door sensor. Running Domoticz v3.5877.

I have 3 of them and they used to work for some months. Then all of a sudden one of the sensors didn't work anymore. Did remove and add the battery again and that solved it.
But since this week all 3 devices don't work anymore. Battery's are still good, so that's not causing it.

I also reset one of the sensors, excluded and included it again. Domoticz finds the sensor, but is not responding anymore when I open or close it.
The blue led on the sensor is flashing, so that really strange.
I have updated the firmware version of my Aeotec Z-Stick S2 to the latest version 3.08. But that doesn't solve it either.

I also did a zwave heal (using a PHP script of Egregius), but that doesn't help as well.

I will try the following steps:
1) Put the logging on to see if anything usefull is logged.
2) Try to upgrade to the latest Domoticz version (I run Domoticz on an Esxi server, so can make snaphot and revert to that easily).

But if anyone has some ideas on how to fix this, that would be great.

Edit: Log is not showing anything usefull.
But this is really strange:
* Device has status closed in Domoticz
* When I remove the magnet, the status stays closed.
* But when I triple click the sensor for a couple of times, the correct status gets updated in Domoticz (in this case open).
* But after that the sensor is still not working in normal use...

Edit 2: Did an upgrade to Domoticz v3.6745 and after excluding and including the door sensors are working again.

Long story short: I RMA'd the broken device and got a new one.
