**PLEASE READ!** Once you have configured the Wi-Fi settings and your Tasmota device connects to your Wi-Fi network, go to the web UI of the device. Click Console and type "Reset 5" (without quotes).  This will wipe flash memory of any Tuya firmware remnants to help prevent future corruption during Tasmota upgrades.

Steps for SSH/Putty Terminal (Copy and Paste)
sudo raspi-config
sudo apt update
sudo apt install git
git clone https://github.com/ct-Open-Source/tuya-convert
cd tuya-convert

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 the header is still there!  Remove the three screws and flash away with no worries of ever bricking the device since you can always recover it.  We aren't so lucky with many other plugs on the market that have to destroyed and/or cut up to get to the RX/TX pads. 

I'm not going to go into the deep rabbit hole debate of ETL, UL listings, CE, etc, but if you require your smart plugs to be UL Listed then these are definitely the way to go!

And of course we soldered RX/TX leads to them and flashed it with Tasmota.  The GPIO pinout is the same and the Sonoff S31 Module option in Tasmota worked great.

The Sonoff S31 Lite is the same PCB but without the power monitoring chip.

And as always, both plugs fit with a small air gap in between when you plug them into the same socket.

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.

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 apply heat to the pad and pre-tinned wire and it pulls right together.  The dupont wire flexes easily as well to prevent the pad from being ripped off the bulb.  Take your time and do not use to much heat!  I've attached some pictures for reference of where the memory pin is to provide power.
