Tasmota on HiHome WPP-16S1 smart plug

Tags: #<Tag:0x00007f77fa773728>

I have the HiHome WPP-16S1 smart plug. link

I am trying to flash tasmota firmware onto it and i’m trying to find the correct pads to connect my flasher to.
There are no obvious pads to solder TX/RX to and the plug is very difficult to open completely.

Here is a picture of the board.

I’we been unable to remove the PCB yet. I think i need to de-solder a few things before i can do that.

This is the chip on the board, the ESP8266EX
https://github.com/arendst/Tasmota/wiki/GPIO-Locations
UART0 is on pin 24 and 25, upper leftmost pins and UART1 is on pin 14 and 23
I’m unsure if i should use UART 0 or 1 for flashing, i have tried probing for the pins on the front side of the PCB but they seem to go to a via and maybe end up on the bottom of the PCB which i have no access to yet.
Any help would be appreciated

Hey, i just got one of these yesterday, and flashed it OTA with Tuya-Convert.

I used the template for the HiHome WPP-16S, and the only issue I’m seeing is my voltage being recorded incorrectly (~275V on a 230V power grid).

Remember to add the model type template:

Hi,
I flashed a couple of these plugs with Tuya-Convert, but unfortunately bricked one when I was updating the firmware. Took it out of the socket too early :frowning:
Do you maybe know a way to unbrick it, by using the soldering method and how this can be done? Any help is appreciated!
