Re: plastic box vs. metal box (electrical)
No, the plastic boxes don't have a fire rating, they are however fire resistant in most cases. That means that they will not free burn when the source of ignition is taken away.
However I really wouldn't worry about automation switches bursting into flames. If anything they are probably safer than conventional switches. Anyway if the switch starts burning the box is the least of your problems.
