Fibaro Smoke Sensor 3.3 - false alarms


remcoploeg

Question

Hi,

 

In the middle of the night suddenly my Fibaro smokesensor v3.3 gave a firealarm (I see  also that the smoke alarm is breached in the HC2 for that sensor). So I went upstairs, but there was no smoke (also no smoke in the history of the sensor in the HC2). I removed the battery to sleep again. I have two questions:

 

- Why did the smoke alarm went off? There was no history of smoke in the sensor in HC2 (the graph was like the whole day). Any idea how I can troubleshoot this?

- Why did the other smoke sensor (gladly for now) didn't went off? 

 

This is the first time it happend and I have 12 Fibaro smoke sensors.... BTW I don't get any notification of a firealarm in the HC2 itself (glady I had a own virtual device) of other mobile devices from the standard interface of the HC2

 

thanks in advance,

Is there any update from Fibaro? I am considering buying some of the smoke sensors, but there are so many negative reviews on Amazon that I am hesitant to go the Fibaro route. TIA.

Fibaro devices are almost good but I can not recommend the smoke sensor in any way. Keep away unless they bring a new improved version of it.

    Off course no update. I am going for the NEST devices now (yes no integration with Fibaro), so if you want to buy 12 smokesensors please sent me a message, I am happy to sell

    I would not even think about selling my 13 ones as I would have a guilty conscience as I know they do not work. They will go to trash.

    If you sell them one by one, then it´s not too bad. 2 false alarm a year is O.K. in a small house. But with 17 sensors it´s not fun.

    Waiting for Fibaro to get some help. I would like to get a debug FW to test.

    was thinking about the graph from the sensor inside. In HC you get an % value that shows the actual dust value.

    I checked this with a friend and we can see 2% to 4% on different times/days. He also had false alarms, but this value was never high.

    So i thougt of getting this value for different controllers, as i assume the sensor is sending this value. But where and when????

    @Fibaro support please answer.

     

    Hi Forum, hi Fibaro Team,

     

    is there any help available, how can I get the data? HC is showing this "actual dust value" so the sensor is sending the data. How to

    get this value to check this?

    Any idea?

    Thanks

    Hi,

    I have 10 Fibaro smoke sensors (002) connected to my HC2 and during the first and a half years had false alarms on six of them. The four that I sent for repair were repeatedly generating false alarms, but did not produce the symptoms any longer after I got them back.  

    I have not configured any associations or scenes. 

    Would like to share two main observations:

    • Alarm going off without smoke, the history shows zero smoke density 0.0. Today this happened a few minutes after replacing the battery.
      The only way to stop the alarm when that happens is taking out the battery. After re-inserting of the battery, the fire status of the module in the HC2 dashboard only disappeared after soft reconfiguration. (Logically, the module will never send a status change after false alarm as the smoke level is already zero).
       
    • I noticed with several smoke detectors that the push-button does not always work as specified. I was several times not able to go through the menu to initiate the range test. The LED went dark right after releasing the button, sometimes the first color change was briefly visible before the LED got dark. At first I thought that flexing of the case would prevent the button from being released properly or that the particular device had a flawed switch, but the audible click indicates otherwise. Today, when it happened again, I took out the battery and re-inserted it after a few seconds. After that, walking the menue by means of the push-button worked flawlessly. This should exclude a mechanical problem. To me, it looks as if the internal software was not started up properly, or maybe the memory was not cleared as it should. If this could lead to false alarms over time? Interestingly, when I replaced the battery today and left the device in such state, I almost immediately got a false alarm (see above). It would be interesting if anybody has made a similar observation, maybe without paying too much attention to it (as I did before).

    BTW: the batteries last for little less than 1.5 years in my installation, leaving reporting intervals at their default setting.

    Hi Team, hi Forum, someone has an idea?

    Hi Forum,

     

    just an update even it´s not positive in regards to Fibaro. I exchanged 5 of the Fibaros with another vendor and had no false alarm any more.

    So, don´t use the Fibaros Smoke Sensors FGSD-002 if they are not in a living room enviroment.

    Also no reaction from the team to my question before, seems these are critical informations from their system.

    But luckily we have some other choices in Z-Wave market.

    CU

    Think I will be getting rid of mine. They look great but too many false alarms and the wife has had enough. What brand did you go with?

    Hi, I bought D-Link, they look the same like the Devolo. Unfortunatly they are stupid and just for Smoke, but I´m fine with this function  ;-)

    I assume there are some more clones of this type, found Philio or Zipato. It´s all the same.

    Hi there,

    I have systematically returned the smoke detector with false alarms but they repeatedly had false alarms again.
    I have posted several info in the Fibaro bug tracker. But it seems that Fibaro is not considering its customers and even does not answer to the posts.

    As I want a reliable solution, I decided to move to another type of smoke alarms which can be connected via radio but also wired.

    Finally this solution has a receiver with a dry contact output allowing to catch the status from the Fibaro HC2 via any type of input device.

    I tested 2 pieces they work very well.

    Manufacturer is Feller from Switzerland (Schneider Electric Group). Batteries are guaranteed 10 years. Compliant to almost all regulations.

    I've ended up with a Nest Protect. We only need one, but ideally should have 2. For now I have one Nest Protect and taken away the Fibaro alarms. Shameful response from Fibaro really. Not seen any negative reviews of the Nest Protect v2 and I trust it much more. 

     

    Now wondering, as I'm 100% Apple user, if I can ditch the Fibaro stuff completely and replace it with other Homekit devices like the HUE motion sensor etc and just sell it all. Only thing stopping me is I have the hall lights on a dimmer which brightens on motion and I can't seemingly get that from a homekit device (been hopeful for years there would be a physical HUE switch/dimmer)

  • I am also moving to Nest, have two for one year now and never had a false alarm. Bye bye fibaro smoke sensors...

    As Fibaro is not handling the case seriously, as they keep on to not doing any proactive proposals to solve the issue.

    I will return today all my smoke detection sensors and of course loose the money invested.

    This device is definitively not reliable and therefore not safe.

    I have finally chosen the both brands, Feller and Hager.

    They are radio connected and two models are existing.

    One for standard areas and one for areas with humidity or dust, the latter detects smoke but also heat.

    I enter the signal to my domestic system via an EcoDevice dry contact input, and all works well.

    We do not have anymore overnight false alarms.

    Fibaro smoke detector subject closed for me!

    Hi, I'm new member and I need smoke sensor for my home. Did you consider at the moment that I need to buy another smoke sensor than Fibaro ?

    Hi all,

    Same problem here. I bought 3 sensors in august 2017. Since a few months I got random false alarms. The seller said I had to remove them from the HC, clean, reset, and reconnect them. Quite strange if you ask me, I never had to clean my old DIY-store sensors..

    hi guys,

    I own 3 fibaro smoke sensors. I have them installed since aprox 3 month.

    All are working without false alarms so far.

     

    I included them in secure mode. How did you guys include them? Secure or unsecure?

     

    I was also concerned buying them as I read the topics here.

    I need temperature and smoke detection, and so far I'm happy with it.

     

    As some report the problems started only after 1,5 years, I'm still hoping they keep working.
