SONOFF IP66 Waterproof Case

Had a leaky pipe right above my outdoor outlet, so I was nervous about water getting in — this case sealed everything up tight even during a full spray test. The IP66 rating actually means business, and the dust-proofing is a nice bonus since my shed gets pretty grimy.

Took this out to the garden after a heavy rain and the inside stayed bone dry, the IP66 seal really does its job against splashes. The dust-proofing is a nice bonus too, keeps the connection ports clean when I’m working in the shed.

The latch seals tight enough that I stopped worrying about my outdoor timer after the sprinklers hit it directly. No moisture sneaked past the gasket even with the hose pointed at it for a solid minute. Fits my existing setup without any fiddling.
