Could this be loosely read as, 'speak of the devil and he will appear'?

I don't think so. It means something like 'Come in, there are gods here too'.

Agree with jno....these words were attributed by Aristotle to Heraclitus who called them out to passers-by as he was seated in a smoky bakers's cottage. " Enter, for here too are gods" - meaning the gods are everywhere even in lowly places.
