Tuya-convert: Teckin SP22 - nothing happens

[gmcbrien]

Nothing happens....

I connect my phone to the newly created vtrust-flash AP, I set the plug to start flashing, I press Enter.... and all I get are dots. Below arte the log files.
NOTE, all logs start with a ^C --> I am NOT touching the keyboard, so I'm not sure this is coming from.

This is a freshly installed Raspberry Pi 3B.

Anybody any ideas where I might be going wrong?

for me too, firstly thought it depends on the plug and checked another one, but same again
just dots and nothing happened

[erichegit]

same for me - blue blinking LED - after hitting "Enter" after 2-3 seconds the LED turns off followed by many dots in the console without doing anything.

[gmcbrien]

@erichegit As mentioned in another post, the LED is supposed to stop flashing after a couple of seconds - to me it seems your device is making a successful connection to the AP - so it sounds to me like you are one step ahead of me :-)

[kueblc]

@gmcbrien Try pulling the latest version, I've merged the Python based SmartConfig

@dave-castle Need more details, pull the latest version, try again, and open an issue with your logs

@erichegit Yes, @gmcbrien is correct, the LED should stop blinking when it pairs successfully. Pull, test again, and post logs

[gmcbrien]

Very good @kueblc - I pulled the latest build and it works perfectly! Many thanks! So I can confirm that the Teckin SP22 https://www.amazon.de/TECKIN-Intelligente-fernbedienbar-Stromverbrauch-funktioniert/dp/B07CDCYLQ6 can also be flashed!

[kueblc]

Very happy to hear it, thanks for the feedback! Others, please open a new issue for any other problems.

[dave-castle]

after pulling latest build it worked for me immediately. Great Job, thanks!

[kueblc]

Awesome, thanks for the feedback

[kueblc]

My bad, I forgot to update the README. I'll update this soon. Try http://10.42.42.42/flash3?url=http://10.42.42.1/files/temp_flash.bin instead.

[erichegit]

thanks - I can confirm flashing with a Raspbian Stretch image is now working :+1:
BUT - I miss a step.
Even after using your link, in my case "sonoff-basic.bin", I only get "Hello World" when going to 10.42.42.1 and nothing at 10.42.42.42.

What to do next=?
With hardware flashing I was used to provide SSID + pwd to access the device after flashing directly via webbrowser - please can you update this steps in the readme?

EDIT: maybe it helps other ones. Afterwards, you have to look via your phone for a new WLAN and then provide your SSID & pwd from your main network.

@kueblc - how can the vtrust-flash WLAN be turned off after flashing?
Restarting the Pi is one option, but I would like a command to turn off the hotspot.

[kueblc]

This is already in the README

Currently a Sonoff-Tasmota v6.5.0 basic build is already included. It will open an WiFi access point named sonoff-XXX.

That's what stop_flash.sh is for

I had the same problem: smartconfig failed, the LED kept blinking. In the end I had to use the offical Tuya android app to get the plug to connect to the vtrust-flash wifi. I was using 99a317efd72b51566ccf774efb645b843d7ed8cb.

I noticed only one difference between the packets smartconfig.py sends and the original Tuya app: The app uses EUSWIlyA7wC5iD as the token_group instead of US000000000101.

[kueblc]

The app sends a unique token and secret for each pairing attempt. It doesn't really matter what we use as we are not actually registering the device to the cloud and instead running our own fake registration server, which couldn't care less what the token, secret, and region are.

Did you connect a device to the vtrust-flash AP while running smartconfig.py?

[bseibold]

I first ran start_flash.sh and followed the instructions, but the plug did not connect. Manually calling main.py again didn't help either. Only when using the Tuya app I was able to get the plug to connect.

If required, I can provide a packet dump of what the Tuya app sends, as well as a flash dump of the original firmware.
