Fibaro buttom

I’m having some problems with my Fibaro buttum. They are very unstable and do not work every time they are activated. They also have difficulty connecting to MESH. Does anyone have any experience?
… And how to perform a software update.

The button itself is perhaps the worst device Fibaro has created. Ever.
From 4 buttons I have only one left after they died one after another, first doing exactly what yours does now.

Of what? Of the button, Homey, Fibaro app?
If you refer to the button, can only be updated if including into a Fibaro controller e.g. HCL or HC2.

Thanks for your reply. Do you have any circuit breakers you would recommend?
