Bests & Worsts Reviews from Amazon

I've powered up this switch and messed with it enough using a temporary hookup to an AC outlet- the UI and capability for the price are great. Home Assistant integration in a switch like this for the price seemed too good to be true. Because it was. I go to remove my old switch from the gang box, and begin to evaluate how I want to mount it in the box, etc, and then realize something that utterly confounded me. These folks actually designed all this for an affordable price, and clearly never even bothered to check if it *even fits in a standard electrical gang box*. That's right, you read that correctly. These fools are selling a product that DOESN'T FIT IN THE FOOTPRINT OF THE SWITCH ITS MEANT TO REPLACE. Frankly, if I was Sonoff I would be ashamed for such an absurd oversight. In a single-gang electrical box it overflows on either side horizontally. In a double-gang it fits (on the horizontal plane); the caveat here is that you aren't going to be using a second switch due to the same horizontal overflow. It literally takes up an entire 2-gang box because these numpties didn't spend the time to bother to get the right dimensions for a country-wide electrical standard in size. This includes both portrait and landscape orientations also- doesn't fit either way. What an absolute joke. I've read elsewhere that some folks had slightly more luck using PVC gang boxes rather than the metal ones present in my home. Metal gang boxes are generally ubiquitous in construction older than a decade or two, which is a vast majority of houses in the US. As far as I know, many are still built with metal boxes, which compounds this even further. I can only assume any success may be due the PVC being more flexible and bowing out in the horizontal wall for the switch to fit- potentially cracking the PVC box in the process and presumably violating electrical code. Regardless, I have exactly no interest in tearing open my wall to replace the entire box with a PVC one for the sake of this questionable switch; read on to find out why the "questionable" moniker fits here. Questionable refers to the part where- despite any assertions otherwise (the numbers vary depending on where you look online)- this switch is equipped with *only* 2 amp relays. Frankly, this seems like a fire hazard waiting to happen to me. In a standard 15/20 amp circuit, everything is rated for 15/20 amps. That should be common sense. Every other switch I have in my home- be it a "dumb" switch, a Z-Wave switch, or otherwise, is rated at the default 15A or higher. The fact that Sonoff is content to bury the rating of these relays- which are a fraction of what they should be rated for- in the specs and act as though its safe is appalling. If someone who didn't know better wired this as a "quick upgrade" (assuming they can fit it in the wall) into a circuit that may have fans, halogen bulbs / drop-lights, hell, even a switch-controlled outlet with something like a window AC plugged into it- think any wall plug device with a motor like a vacuum- then they would potentially be putting their home at risk for fire or similar electrical issue. There's just no excuse. Honestly, I'm scratching my head as to how this got any legal certification in the first place. I bought this because the price was great, it fit my need, and overall seemed like a pretty good product. After dealing with what I've outlined above and the *OBVIOUS* corners that were cut (at least with the US version), I have to say I'm disgusted. There was clearly a great idea at the core of this device- the ESP3X heart running it and the okay-ish Nextion screen for user UI all in a small package- but its clear Sonoff woefully missed the mark on this to the (potentially fatal) detriment of their customers. I want to like it and have it work so badly, but after this nonsense I'm more inclined to stick a Raspberry Pi in the wall and mount a screen in front of it. Probably an actual cheaper solution- certainly a safer one too.
