I have low voltage wire under my deck. I would like to drill a small hole (1/4 in or less) and feed the cable through the deck ledger board and the house's rim joist so that I can keep the transformer inside (the basement which is unfinished). I would then fill the hole with silicon to keep water and bugs out.

Is this an absurd idea? Is there a better way to do it?

I'd seal around the cable with duct seal, instead of silicone.

Duct Seal

It stays pliable, and will not interact with the cable jacket.
