Okay, so I finally caved and got this meross outdoor smart plug after seeing it everywhere. And wow - why didn't I do this sooner?!
First off, setup was stupid easy. Like 'connect-to-wifi-while-making-coffee' easy. The app is clean and doesn't make me want to throw my phone like some other smart home apps *cough*.
I'm using it for my patio string lights and OMG the convenience! Being able to turn them on from bed when I forget? Priceless. Alexa integration works perfectly - though my neighbors probably think I'm nuts talking to my lights.
The waterproofing is legit. We've had some serious rain lately and zero issues. The covers actually stay closed too, unlike some other outdoor plugs I've tried.
Only minor gripe? It's a bit bulky so heavy cords can pull it out if you're not careful. But for $35? Totally worth it for how much use I get out of it.
Pro tip: The sunrise/sunset scheduling is perfect for holiday lights - no more coming home to dark decorations!
