It wasn’t effective. Water found a way in so the POE splitter shorted and died, it’s a pretty gross photo so I haven’t attached it in this post, it’s below.

I got another splitter, gently tapped at the seams with a hammer until the housing separated and then heatshrinked it just because I could.

This time the connector will be inside the box and hopefully fare better:

Fog, condensation, moisture can still get inside, a full proof solution could be a potting compound which you pour in the box and let it dry.
