Nice Also see they have a nice way of installing a fuse inside the device ;) |
|
Pls give it a try and let me know if the power monitoring works as expected. |

Hi,
xnrg_01_hlw8012.ino changed to |
|
Thx. Just fixed. |
|
thanks, works great now. |
|
@Clooney82 Awesome - if you have time please add some wiki information for this device so that other users can also use it easily. Thanks! |
|
@Clooney82, did you find a non-destructive way to open them up? |
|
Has anyone worked on the SP23 version? |
|

@Clooney82 Hi, EDIT: and some more questions arose...: |
|
So I just connected 3.3V, GND, RX & TX to my USB2TTL adapter... RX to TX and TX to RX... Is it possible to verify that the serial connection is successful? |
|
Ok I made some progress... So far... going into flash mode again... going into flash mode again... going into flash mode again... Then I disconnected power and reconnected power but nothing |
|
Well I guess I have to compile a customized binary instead of using the pre-compiled ones? |
|
Sorry for polluting this thread. I made more progress. I made changes as @Clooney82 described in his first post in the file Sonoff_template.h, Then I added my AP details in my_user_config.h, compiled and erased and flashed and then the device was reachable in my LAN. I will now reassemble the plug and see if everything else works. |
|
The plug works now on AC, I can switch it. But how can I show power consumption? There is no such option in the web interface... |
|
Problem solved: #4204 |
|
Is there any chance to flash it "over the air"? with plenty force and hot air, I got it open (quite ugly...) |
|
I now added an external power supply (old PCs psu 3.3V) but still get exactly the same problem. When I change RX/TX I just get a timeout, so it should be correct. Any Idea? Edit: |
|
@matthewjporter |
@ocl80 Thanks for the update, Will give it a bash How did you get it open, Hot air gun and sharp edge tool i guess, did it destroy the case? Does it still do the power monitoring? Cheers |
|
@matthewjporter I don't have a hot air gun so just a sharp edge tool in my case. I might have been lucky, but with a bit of patience it opened nicely and you wouldn't know now it is back together.

Hi All Just to update on the "dismantling" of the Teckin SP23. I have taken some pics as I go as it may help so here they are: This is the Unit I have and is currently on Amazon and at £10 each is not bad for a power monitoring plug https://www.amazon.co.uk/TECKIN-Monitoring-Function-Anywhere-Required/dp/B07D7BH6N8/ref=sr_1_1?ie=UTF8&qid=1541589149&sr=8-1&keywords=teckin
This is what I used to get into it (Heat gun helped as it is glued together on the edges) Only slight damage to the edging but heat gun will fix when closing up This is what I found on the inside. This seems to be a new design! I noticed that it is not using the TYWE2S chip, but is still esp8266 based After de-soldering the Live & Neutral the board came right off Next steps are a work in progress:
Hope this helps right now for anyone else looking at updating these units |

Hi there, I also bought a 4 pack of SP23's from Amazon, and was annoyed to find that they were sealed shut. I didn't do as good a job as you did about opening them, but in case you haven't got the pinouts yet, I've worked these out and have flashed mine with the standard SHP2 binary of Espurna which works nicely for me. The pinouts are as follows: Cheers Andy |

Hi, just tried to flash my 2 Slitinto Model NX-SP202 (Dual Outlet) using tuya-convert. So far managed to flash one of the two with Tasmota image shipped with tuya-convert. Now my 2 questions:
Your help is really appreciated and I want to thank everyone who can point me to the right direction or even give me the final solution. |
|
Hi,
First, are you using the stop flash and then start flash script for the second and further units? This worked for me.
Second, as of version 6.4.1.17, Tasmota includes a “template” facility that does what you need - you can define your module pin by pin. See https://github.com/arendst/Sonoff-Tasmota/wiki/Templates
Perhaps you could wait for the next release or build it yourself?

Hi,
just tried to flash my 2 Slitinto Model NX-SP202 (Dual Outlet) using tuya-convert.
Used VM-Ware image of Kali Linux 2019.1
Installed requirements using ./install_prereq-sh and installed missing npm using apt-get install npm
So far managed to flash one of the two with Tasmota image shipped with tuya-convert.
Now my 2 questions:
really don't know why the second does not want to get flashed. Tried the fast and slow blinking mode and restarted the start_flash.sh several times and waited quite long... nothing happens. The log files are fine and also observed the 4 different SCREEN sessions. My android connects well to the access point but this is the only reaction in the 4 SCREEN sessions.
Is there a possibility to find out why my second Slitinto does not connect?
Should I see the section "sending packets and waiting 60 seconds" every 60 seconds again? I see it only once...
What Tasmota configuration does you use for Slitinto Dual Outlets?
I selected "Generic (18)" as Module Type and found out that
Button1 is on GPIO0
Button2 is on GPIO16
Relay1 is on GPIO15
Relay2 is on GPIO14
But then I don't see metering information.
Do I need to flash a different Tasmota Version or is there a better "base module" to configure Slitinto devices?
In Tasmota WIKI "Templates" I saw example for Blitzwolf with GPIO5 selected as "BL0937", but in Generic Module I cannot select such a function.
What is the trick to get Slitinto fully working with 2xButtons,2xLEDs,2xRelays and Metering Sensors?
Your help is really appreciated and I want to thank everyone who can point me to the right direction or even give me the final solution.

Hi, thank you very much for your quick answer. Will have a closer look at the template facility. Found the wiki article with the example of Blitzwolf and just wanted to select the mentioned entries in the web config... Any further ideas to find out why my second item denies to get in contact with tuya-convert? |
|
To make the flash happen, the plug needs to be in the mode where the led blinks rapidly.
To get into this mode, the button needs to be held for a few seconds.
You may have been lucky that the first plug you tried was in that mode when first powered on - one of my six plugs was like this.
Also, remember to follow the instructions precisely and follow the sequence that is specified by the script - the start_flash, connect a Wi-Fi device to the temporary AP, then power on the plug. Hold the button if needed to get the led to blink rapidly. The initial flash should complete within a few sips of your cup of tea / coffee. You can then load the firmware you need. Beware - the most recent firmware is bigger than 512k so you need the initial flash to be smaller than that!

Yes, I use stop_flash between the trials. Also rebooted the machine several times in between to be sure that all is fine again.

Will try to find out if my knowledge is enough to create my own template and upload a custom made image... at least for the first of my modules.
Any further ideas to find out why my second item denies to get in contact with tuya-convert?
Do I have to take care about a special timing when starting tuya-convert or should it be sufficient to simply start tuya-convert, plug in the device and start blinking and just wait some minutes?
Can I see somewhere whether tuya-convert resends connection packages every 60 seconds or not?

f**k, got contact by a trick but network connection had an issue and now the device blinks slowly without any other reaction. Button press does not seem to have an effect. Long press does not work anymore. Trick was (and I'm convinced that this could help other people in getting in contact to the device):
Any ideas how to reactivate the device? |
|
just few more infos:
after got contact via the app trick I executed "curl http://10.42.42.42" and "curl http://10.42.42.42/flash3" |
|
Yes, the slow flash from Tasmota firmware means that it needs to be configured.
Glad you got things sorted.

Did the same with the other plug if I remember well

made my day!!! thought it was bricked but it's waiting for me to type in WIFI credentials by opening an Access Point... (and I already began to search my rubber hammer :) ) |
|
For my Teckin SP22 the configuration Blitzwolf SHP2 is not working at all 👎 If there wouldn`t be a much to high Voltage of 280 V (230V should be fine) How can you manually adjust it? |
A little bit of hardware or an unpatched Plug is helpful. |
|
I managed to open my first Teckin SP22 and the inside is fully similar to the photos in the first post of this thread. I now have a very noobish question; can I simply solder the wires to the main board or do I have to desolder the tywe2s first? |
|
Looking at write-ups for flashing (regardless of firmware), it looks like you can flash "in place" without removing the module. Search |
You can flash in place using any of the available methods based around the Sonoff Tasmota stuff above. |
|
Tuya-Convert - depending on the "newness" of your device. Newer devices are coming with patched Tuya firmware which disables the Tuya-Convert OTA flashing option. |
How can I find out which firmware version is installed without using the Chinese software? |
|
It's a Catch22. To see what Tuya version is on the device you have to connect to their app. However, if you connect to their app, it will upgrade to the latest Tuya firmware without asking... thus no longer able to use Tuya-Convert. The best way to know if Tuya-Convert works is to try it on your device right out of the box. If it displays nothing bu a never ending string of periods Mike |

Well, there's recent activity as of late last night that there may be some progress on Tuya-Convert which can circumvent the patched Tuya firmware. Some work left to do to update documentation and installation procedures. That should be ready soon. Having said that, there are also some users reporting that some newer versions of the Teckin SP22 are coming with a WR2 WiFi module which is based on an RTL8710BN chip (i.e., NOT ESP82xx)! The Teckin SP22 also comes branded as BlitzWolf BW-SHP2 and HomeCube SP1. Finally, for any ESP82xx based device, once it is in programming mode, the firmware that is on-board can be downloaded (i.e., backed up). Mike |
|
@meingraham any hint on where I can find that new version? The tuya-convert GitHub does not indicate anything on this... |
|
I would think that there should be something ready by the beginning of the week. I did see that the current process took more that one attempt to finally complete successfully and that so far light bulbs are still not being flashed. This sounds reminiscent of the original work. It took a bit of refinement. This will probably take a bit of time to "smooth out". |
|
That looks promising. I will prepare the hardware during weekend that I can try soon after release. I have to find out if they have the wrong Wifi module so I can send them back in case. |
|
For those of you looking to flash teckin SP22, here's what I did to get mine working with OTA convert 2!
Follow the instructions in the vid...
Then I proceeded to flash using the curl commands... |
|
there's a working fork for all your sp22 ;-) https://github.com/ct-Open-Source/tuya-convert/issues/273 |
Today I was able to flash all my 4 Teckin SP22 bought 2 Weeks ago from Amazon.de Cheers, |
|
Tuya convert also works with Slitinto SP202, even with new firmware. |
yes, i successfully opened it without destroying, just left some minor marks. I used a flat screw driver and some opening picks. |
|
If I may suggest something; opening the SP22 is very easy if you use a rubber hammer. Simply hit (not too hard, but harder than you think) the glued rim from the side. After a few blows you will see both parts separating. It leaves no marks whatsoever. |
|
that really works, just did it 😃 |
and others
Hello together,
just bought a 4pack of Teckin SP22 because, I knew they were identical to Blitzwolf SHP2 / Gosund SP1.
I´ll got them yesterday an recognized that there is a new Version of them out now.
Layout of new HW:
TYWE2S:
Details:
Good new is, that i managed to get them to work.
For flashing I used this page: https://github.com/arendst/Sonoff-Tasmota/wiki/CE-Smart-Home---LA-WF3-Wifi-Plug-(TYWE2S)
For basic feature I used a generic board in configuration
GPIO1 Button 1
GPIO3 Led2i
GPIO13 Led1i
GPIO14 Relay1
after this was working I tried to figure out power measuring feature.
In sonoff_template.h I added a new entrie of for the Teckin based on the Blitzwolf setup.
After a few tried I got a working one.
Only Voltage was not shown correctly, so I calibrated it via console an VoltageSet
Hope this one will get official support.
BR, Jochen
