No flashing means it's awaiting a firmware upload. Flashing means it's waiting to be paired, meaning that the firmware is running on the ESP. An indication that you have grounded to pin is when the onboard led DOES NOT flash continuously. Grounding the IO0 point when powering up the circuit board also takes some practice.

It did take a bit of trial and error to adjust the bent Dupot beardboard leads so that they are connected to the Tx and Rx solder points of the ESP carrier circuit board. Everything worked, great!īUT, no one wants to unsolder a circuit board of a Smart Plug every time they want to replace its stock firmware with Tasmota! That leads us to the next question.

GOSUND SMART PLUG HOW TO

There are lots of websites and YouTube videos that show you how to do downloading Tasmota onto these types of circuit boards.Īfter downloading Tasmota the board was powered up and tested. I won’t publish the details of programming the ESP. Grounding the IO0 pin is necessary when connecting power so the board enters programming mode. In then soldered wires to the Tx, Rx, 3.3V and Gnd terminals of the ESP carrier board and downloaded Tasmota onto the ESP with FlashESP8266.exe. The Tx and Rx connections are on the back of the ESP carrier board and on the bottom of the smart plug circuit board.įor the first plug I removed the board by desoldering the Line, Neutral and Ground terminals. These have an ESP8266 or one of its relatives as the processors. Question 2: How do we reprogram this smart plug with Tasmota? Sometimes it took a few hits but eventually the back cover separated from the housing and the plug came apart.Īs you can see there is no any visible damage on the smart plug outer housing. Since the back cover fits inside the reducer and wasn’t supported it could be driven out of the Smart Plug housing. To ensure that all three (3) pins were pushed on simultaneously a piece of steel was balanced on top of them and struck with a hammer. A 2” to 1-1/2”PVC reducer fit those requirements. Something that would support the outer housing, but not the back cover of the Smart Plug. I then needed a round hollow shape whose inner diameter was the same size as the rim on the Smart Plug outer housing. Flat pieces instead of nails may work better, but I didn’t have any in my inventory. It took a screw and a couple of nails that were cut to size so that all three (3) stuck out the same amount from the front of the plug. What if we could push from the inside on the back cover? Could that push the rear cover out of the plug without damaging the housing? It turns out that it is possible. Question 1: Is there a way to disassemble the plug without damaging its housing? I have seen a number of videos how these plugs are disassembled and in each one the method damages the plug housing.
