I’ve got a problem with my Z-Wave smoke detectors. I’ve started with the Fibaro smoke detector 2 and equipped almost every room with this sensor. Unfortunately, there are false alarms every now and then. It happens in different rooms and the sensors are from different batches (2015, 2016, 2018, 2019). Sometimes the controller is sending notifications about that event and sometimes there are no notifications. Old/new batteries make no difference. The hub doesn’t seem to have any influence on this either (false alerts with Vera and Ezlo).
I tried another brand of Z-Wave smoke detector: Heiman HS3SA-Z. But I’ve als got a false alert with this detector. I wonder if that’s a problem with all Z-Wave smoke detectors or if there is a brand that is more reliable. Is it the small size to blame? Why do 5€ smoke detector from the hardware store don’t generate false alerts (I’ve never had one in many years at least) while 50€ Z-Wave smoke detectors do that more often?
What should I do? Replace all expensive Z-Wave smoke detectors with cheap ones? Or some kind of WLAN smoke detectors that can be intrgrated to the hub?
