Fibaro switches and sensors - do they work fine in generator power





I have bought HC3 and different switches and sensor modules recently. My automation engineer says that it is not advisable to install these if the house has the backup generator power as some switch modules may not work properly in the generator power. I have invested considerable money for the automation, this is a bit surprise to know this at this stage.  Can anyone pls throw more light here? 


Thanks in advance.

Grid power is generally very stable in terms of frequency and voltage. Backup generators not necessarily so - they can produce higher harmonic distortions, voltage spikes etc.  It's not just Fibaro devices at risk, any electronics can be sensitive to generator power. I'd get some advice from an engineer about how to lower your risk....filters, UPS etc may be an option. It's going to cost you more of course.
