STAY AWAY from Gosund plugs

[samip5]

I got confirmation from their support that most of their plugs are already upgraded versions and cannot be downgraded.

For reference:

Hi Skyler,
Thank you for your email.
Most of our plugs are already upgraded and they no longer support flashing to Tasmota.
We are sorry to inform you that upon checking, your smart plug is an upgraded version. Therefore, the firmware cannot be updated to v1.0.8.
We are hoping for your understanding.

Which Version of Tasmota do you have?

Main Module lists version as v1.1.15 and Other type: v1.0.7 so expect every single one of these to be non-downgradeable if you're currently thinking about them.

I've just flashed Gosund EP2 smart plugs with the firmware version: 1.0.8 4 with Tuya converter installed on Raspberry Pi4 - i had no Issues with flashing.

That version is exactly the ONLY ONE which works, but most ones you can buy anymore are running newer than that, and thus will not work.

you should still be able to open them up and flash them

Doesn't matter, as I'm not going to open it.

if you get some old models from the store then you may have 1.0.4 firmware.(Probably tuya forced them to stop flashing EP2 to customers plugs) But there is also EP2 with a beken chip. (EP2 RTL as gosund support says)
gosund ran out of esp chips??

[TrustedFloppa]

so sad they are patched, i didn't get to flash tasmota on mine :(

Thanks for the heads up. I have a few old gosuns kicking around which work and too many Sonoffs. Out of interest, does anyone recommend a nice quality smart plug for the UK with tuya-convert compatibility still?

Well, to my surprise and great delight, I have just managed to flash two Gosund UP111 plugs that I bought from Amazon last week (July 2024). So do not give up all hope!

Notes from my experiences:

• I spent a long time trying but completely failed when using a Pi Zero W. It seldom managed to generate the vtrust-flash SSID at all, and when it did, I couldn't connect to it. I then switched to a Pi 4. (Temporarily re-purposing my Octoprint Pi is so easy when I just have to switch SD cards :-) )
• I was using the standard Raspberry Pi OS Lite, which is based on Debian Bookworm and installs Python 3.11. When you try to run install_prereq.sh, it may refuse, saying that it's an externally-managed installation... (They try to encourage you do do everything in virtualenvs or containers or whatever.) If, however, you just want to go ahead and install the python dependencies alongside the system site packages in the traditional way, run sudo rm /usr/lib/python3.11/EXTERNALLY-MANAGED before starting.

Then I basically just followed the instructions, noting that, as ever, it's very important to make sure you successfully connect a phone or something else to the vtrust-flash network before trying the flash procedure, and that, if at first you don't succeed and need to retry, you may very well need to do this again.

Anyway, your mileage may vary, but I'm a happy bunny - and thanks for all those behind this very useful project!

Well, that may be old manufacturing date like before updated firmware, so in this case you were mostly lucky lol
