today, i boot up the same rpi3 so i can flash some more devices (same smart plugs bought at the same time but didnt flash until today) but rpi refuses to work. looks like the rpi tries to start up the AP but i dont see the " vtrust-flash" access point
command “./start_flash.sh”
error shows “screen: command not found”
i tried a different rpi3 but none worked.
On January 28th, 2019, Tuya started distributing a patch that prevented older versions of tuya-convert from completing successfully. We have since developed a work around to enable OTA flashing on some newer devices, but Tuya has since released yet another patch.
To ensure the best chance of success, do not connect your device with the official app as it may automatically update the device, preventing you from flashing with tuya-convert. It is up to the individual brands to update their firmware, so some devices may be affected sooner than others.
Unfortunately many devices have already been shipping with the new patched firmware, evident by a PSK ID beginning with 02 in smarthack-psk.log. There is no workaround at this time. Additionally, manufacturers have been silently switching from the ESP82xx based modules to other chipsets, making it impossible to install alternative ESP firmware on these devices.
it’s not the Topgreener smart plug with energy monitor. it’s something with my rpi3. the rpi3 refuses to create the vtrust-flash SSID. I did not update my rpi nor tuya convert so that’s why it is extra strange
well, today, i got much further than before! i do see vtrust-flash SSID and used a phone to connect. it didnt ask for a pw to connect to that ap, weird.
but now i am stuck at “resending smartconfig packets” as seen here
ok. happy to say i got it working now!
when i started from scratch all over again, i manually uploaded the github files into the rpi3. the clone github commands no longer work. next, running the commands wont work due to permission issues when i uploaded. so i went into FTP and manually change some py and sh files permission to 755, all executeables instead or read only. working perfect now! thanks everyone!!!
this smart plug with energy monitor was bought in March 2021. so it still had the older fw. no idea what fw it has if you buy now. i got it flashed after my rpi3 issues were fixed today. works great!
Anyone know how to fix the vtrust-flash SSID not authenticating? I’ve tried 2 different phones and one table and it just won’t let me connect to the network.
