p.kaczmarek2 2829 0

TL;DR

  • Flashes a LSPA9 smart socket that uses an unusual TYWE2S module pinout, installing Tasmota on the device.
  • Uses a soldering guide and esptool.py to program the ESP8266, with an alternate TYWE2S pinout that exposes GPIO0.
  • Flags that this TYWE2S layout does not match Tuya documentation and corrects a video typo that once named TYWE3S.
  • Points to related guides for CB2S, WB2S, and LN882 LSPA9 versions, plus Tasmota Device Groups compatibility with OBK sockets.

  • The image depicts a flashing guide for the LSPA9 socket with the TYWE2S module.
    This is a short programming guide for a LSPA9 socket that is using a strange TYWE2S version with non-stand pinout that does not match Tuya documentation. Video includes soldering guide and flashing method for ESP8266 with esptool.py. We'll flash Tasmota to this socket.



    ERRATA: On the video, TYWE3S name is once used. It should be TYWE2S, obviously.

FAQ

TL;DR: This FAQ is for LSPA9 owners with the new TYWE2S layout. In 1 video, the guide shows soldering and says "We'll flash Tasmota" using esptool.py on an ESP8266-based plug. It solves the common problem where the TYWE2S pinout does not match Tuya documentation. [#20993773]

Why it matters: A wrong module ID or wrong pinout sends you to the wrong flashing method and can stop the LSPA9 from entering programming mode.

Module in LSPA9 Platform noted in thread Correct guide path
TYWE2S with alternate pinout ESP8266 This video guide plus the alternate-pinout article
CB2S / WB2S Different hardware branch Use the other flashing guides linked in the post
LN882 version Different hardware branch Use the separate LN882 thread linked in the post

Key insight: The critical takeaway is not the plug name but the exact module inside it. On this LSPA9 revision, the TYWE2S uses an alternate pinout, so you must follow the TYWE2S-specific GPIO0 method rather than standard Tuya pin maps.

Quick Facts

  • The post was published on 2024-03-07 and presents a short LSPA9 programming guide for a TYWE2S module with a non-standard pinout. [#20993773]
  • The guide targets ESP8266 flashing with esptool.py and the intended firmware is Tasmota. [#20993773]
  • The author adds an erratum: TYWE3S is mentioned once in the video, but the correct module name is TYWE2S. [#20993773]
  • The thread links 3 alternative paths beyond the main video: one for the alternate TYWE2S pinout, one for CB2S/WB2S, and one for LN882 hardware. [#20993773]

How do I flash Tasmota onto an LSPA9 smart socket that uses the new TYWE2S with the alternate pinout?

Use the TYWE2S-specific video and the linked alternate-pinout article, not the standard Tuya TYWE2S map. The post states this LSPA9 revision uses a strange TYWE2S version and flashes Tasmota with esptool.py on ESP8266. 1. Open the LSPA9 and confirm it has TYWE2S. 2. Follow the soldering guide in the video. 3. Use the GPIO0 method from the alternate-pinout guide and flash with esptool.py. [#20993773]

What is the alternate TYWE2S pinout, and how is it different from the standard Tuya TYWE2S documentation?

It is a TYWE2S pin arrangement on this LSPA9 that does not match Tuya’s standard TYWE2S documentation. The post explicitly says the module uses a strange TYWE2S version with a non-standard pinout and links a separate article for the alternate mapping. That means you should rely on the linked alternate-pinout resource for this hardware revision, not the usual Tuya reference. [#20993773]

Which GPIO0 connection is needed to put the non-standard TYWE2S module into flashing mode on the LSPA9 socket?

The required GPIO0 connection is the one shown in the TYWE2S alternate-pinout guide linked from the post. The thread does not restate the exact pad map in text, but it makes clear that the standard Tuya TYWE2S documentation is wrong for this LSPA9 revision. Use the video and the linked alternate-pinout article together when entering flashing mode. [#20993773]

What tools and soldering steps are required to program an ESP8266-based LSPA9 socket with esptool.py?

You need the video’s soldering setup and esptool.py for the firmware write. The post says the guide includes both a soldering guide and a flashing method for ESP8266 with esptool.py, aimed at putting Tasmota on the socket. Follow the TYWE2S-specific wiring shown there, because this LSPA9 uses an alternate pinout. [#20993773]

Why does some LSPA9 hardware use a TYWE2S pinout that does not match the official Tuya pinout?

The thread shows that at least one LSPA9 revision ships with a TYWE2S variant whose pinout differs from Tuya’s published layout. It does not explain the manufacturer’s reason, but it clearly identifies the result: standard TYWE2S documentation does not match this board. For this hardware, the practical fix is to use the linked alternate-pinout guide instead of the official Tuya map. [#20993773]

What is esptool.py, and how is it used to flash firmware onto ESP8266 devices like the TYWE2S?

"esptool.py" is a flashing utility that programs ESP8266 devices, writing firmware onto the chip through a wired connection. In this post, it is the named method for flashing an ESP8266-based LSPA9 socket with Tasmota. The workflow is simple: solder the required wires, put the TYWE2S into flashing mode with the correct GPIO0 method, and use esptool.py to upload the firmware. [#20993773]

How can I identify whether my LSPA9 socket has a TYWE2S, CB2S, WB2S, or LN882 module before choosing a flashing guide?

Identify the module first, then choose the guide that matches that exact label. The post separates the methods into four hardware paths: TYWE2S, CB2S, WB2S, and LN882. If your plug has TYWE2S, use the ESP8266 esptool.py guide; if it has CB2S or WB2S, use the other flashing guides; if it has LN882, use the dedicated LN882 thread. [#20993773]

TYWE2S vs CB2S vs WB2S vs LN882 in LSPA9 sockets — what are the main differences for firmware flashing and custom firmware support?

The key difference is that they need different flashing guides. The post ties TYWE2S to an ESP8266 workflow using esptool.py and Tasmota, while CB2S, WB2S, and LN882 are sent to separate resources. So the main decision point is the installed module, not the LSPA9 shell. Choosing the wrong guide risks using the wrong pinout and wrong procedure. [#20993773]

What should I do if I accidentally follow a TYWE3S guide when my LSPA9 socket actually has a TYWE2S module?

Stop and switch to the TYWE2S guide immediately. The post includes an erratum stating that TYWE3S is mentioned once in the video, but the correct module name is TYWE2S. That correction matters because this LSPA9 also uses an alternate TYWE2S pinout, so the safe path is the TYWE2S-specific video plus the linked alternate-pinout article. [#20993773]

How can I troubleshoot flashing problems when esptool.py does not detect the TYWE2S in an LSPA9 socket?

First verify that you actually have TYWE2S and that you used the alternate-pinout GPIO0 method, not the standard Tuya map. The thread’s main failure case is hardware mismatch: this LSPA9 revision uses a non-standard TYWE2S layout, while CB2S, WB2S, and LN882 require different guides. If detection fails, recheck the module type, soldering points, and the linked alternate-pinout instructions before trying again. [#20993773]

What is Tasmota, and why do people flash it onto Tuya-based sockets like the LSPA9?

"Tasmota" is custom firmware that runs on supported smart devices, replacing vendor software to give local control and broader integration options. The post says the goal is to flash Tasmota onto the LSPA9 and adds that Tasmota sockets can integrate with OBK sockets through Tasmota Device Groups. It also frames the project as a way to run IoT devices in a private, cloud-free way. [#20993773]

How do Tasmota Device Groups work when integrating Tasmota sockets with OpenBeken or OBK sockets?

They let Tasmota sockets integrate seamlessly with OBK sockets. The post says this directly and links a separate video about Tasmota Device Groups for that setup. It does not describe the protocol details in text, but the practical takeaway is clear: flashing Tasmota on one LSPA9 does not isolate it from an OpenBeken-based environment. [#20993773]

What safety precautions should I follow when soldering wires and flashing firmware on a mains-powered LSPA9 smart plug?

The thread does not provide a dedicated safety checklist. It only says the video includes a soldering guide and a flashing method for the LSPA9 socket. For this FAQ, the reliable thread-based advice is to follow that guide exactly and avoid mixing it with unrelated TYWE2S, CB2S, WB2S, or LN882 procedures. [#20993773]

Where can I find the correct flashing method if my LSPA9 socket uses a CB2S or WB2S instead of an ESP8266-based TYWE2S?

Use the separate CB2S/WB2S flashing guides linked in the post. The TYWE2S video is only for the ESP8266-based socket variant with the alternate TYWE2S pinout. If your module is CB2S or WB2S, the post explicitly sends you to another guide list, and if it is LN882, to a different thread. [#20993773]

What are the signs that the TYWE2S flash process completed successfully and the LSPA9 socket booted into Tasmota correctly?

The thread defines success as an LSPA9 socket flashed with Tasmota by the video’s ESP8266 esptool.py method. It does not list boot messages, LED patterns, or timing values in text. If you need confirmation criteria, the post points you back to the video workflow and to the Tasmota integration path mentioned for Device Groups. [#20993773]
