First Impressions: The S40 arrived looking sleek and sassy, like a miniature tuxedo for your outlet. Setup was easier than deciphering Ross's love life – just download the app, follow the instructions that even Chandler could understand, and boom, you're controlling things from your phone like a digital puppet master.
My "Genius" Hacks: Now, I'm not exactly Tony Stark in the brains department, but the S40 unleashed a tidal wave of "brilliant" (cough, cough) ideas. Like, imagine this: setting a schedule so your coffee maker starts brewing before your alarm, ensuring you stumble out of bed to the glorious aroma of caffeine, not the existential dread of another Monday. Genius, right? Except I forgot to fill the water tank, resulting in a volcanic eruption of burnt beans spewing across the kitchen.
Pet Shenanigans: My mischievous mutt, Winston, also discovered the joys of the S40. Turns out, paws make excellent conductors for the touch-sensitive buttons. Cue the symphony of lights! My living room became a disco ball for one (fur coat optional), and for a brief, hilarious moment, I thought I'd stumbled into a dog rave.
Actual Useful Features: Okay, enough silliness. The S40 actually has some genuinely awesome features. The energy monitoring is like a financial therapist for your appliances, revealing which ones are secretly guzzling electricity like thirsty hippos at a water buffet. I even used it to schedule my lamp to turn on at sunset, creating a mini-sunset in my apartment while I sipped margaritas and pretended I was on a beach (bonus points for using the S40 to control the margarita machine - don't judge).
The Verdict: Overall, the SONOFF S40 is a hilarious and surprisingly helpful addition to my life. It's like having a mischievous tech gremlin living in your outlet, but one that actually makes your life easier (and slightly more ridiculous). So, if you're looking to add a touch of laughter and automation to your home, the S40 is definitely worth a plug. Just remember, keep your furry friends away from the buttons, and maybe invest in a fire extinguisher for your coffee maker.
Rating: 5 out of 5 stars (with one bonus star for Winston's disco dance party)
P.S. Don't ask about the time I tried to control my air conditioner with the S40 and ended up turning my apartment into a wind tunnel. Let's just say, cats hate flying.
note: this only works on 2.4ghz wifi, NOT 5ghz. Make sure your network has a different sid for the 2.4 vs the 5ghz network and this device will work fine. ewelink software was intuitive and easy to set up on android device. Also works well with google home.

Top reviews from other countries
So far so good. One thing I didnt like is that it tends to fall of the wall depending on the weight of the plug head. My Car charger god a pretty large and quite heavy head and it comes out and I had to add extra support to hold it in place.
Now that they're flashed, I run a custom template to report the current and wattage to Home assistant. The build quality is solid and they have so far responded really well.
This is really the best of both world, a great product flashed with a custom firmware I have 100% control over.
