Sonoff S31 - UL Listed - What's different?

I recently picked up the Sonoff S31 and Sonoff S31 Lite smart plugs that are UL Listed.   They new S31's bear the UL listed logo on the box and the back of the unit itself.  Let's crack them open and see what makes them tick.

The Lite version is the same plug except it does not bring any power monitoring capabilities to the table.  With all new hardware revisions of various products I was worried that my favorite smart plug was going to go the way of the Sonoff Mini and not have any easy access headers for flashing the open source firmware of your choice.  The Sonoff S31 line of plugs easily fit two plugs on the same wall socket with ease, utilizes screws in case you want to open the device, and has easy to solder RX/TX pin headers; which is why the S31 is still my favorite smart plug!

Of course I took the device apart and compared it to the previous non-UL S31 model (pics below).  I was excited to see they kept the same PCB that handles the ESP8266 side of things which meant…

We spent quite a bit of time setting up 15+ bulbs, photographing, videoing them and testing out each channel with LUX sensors.  All the data and video has been compiled for you to make your own decisions, although I do tell you which bulb is my favorite based on various factors/features.

Lohas RGBW Bulb Recovery via Serial USB

First you may ask why do we need this if we can currently do these with Tuya Convert?  Pay attention to that word "currently".  You can never beat the tried and true method of connecting up those RX/TX lines via serial to flash your ESP82xx devices.  99.9% of the time it just works!  If you have any issues or firmware corruption it is stupid simple to just recover your device. 

Luckily the quite awesome performance to cost ratio bulbs that Lohas provides they also have the RX/TX pins exposed for us right on top under the diffuser.  That's quite rare in a bulb, especially in one of my favorite bulbs!  The only issue I've found is the 3v3 pin does not work!  But no fear!  It is easy to solder to the 3v3 pin on the flash memory chip. 

First apply a bit of flux to each pad you will be soldering to then apply a small bulb of solder to the pads. 

Next take a dupont jumper wire and cut off the ends.  Apply a small amount of flux and then tin them with solder. 

Then simply …
