Can Tuyaconvert be used to ascertain if I have a ESP core?

[KDMcMullan]

Hi. Trying to use Tuyaconvert, because I've bought a device and I don't know if it's an ESP core and i don't want to crack the case. If it's not an ESP, I'll take it back to the shop for a refund.

Tuyaconvert tells me:
Your device's firmware is too new.
Tuya patched the PSK vulnerability that we use to establish a connection.

I'm hoping to ascertain how accurate this diagnosis is. If it is genuinely that the firmware is too new, I'll do a serial flash, which is my usual method.

I did consult https://github.com/ct-Open-Source/tuya-convert/wiki/Collaboration-document-for-PSK-Identity-02. I found my smarthack.psklog and it does, in fact have ID 2.

Does that mean I have the ESP? Is it possible to know?

Thanks.

Check the MAC address against an OUI database to see if the vendor is Espressif. You can find the MAC address of your device in the logs if tuya-convert made contact.

Bother. According to https://macvendors.com/, the vendor is "Tuya Smart Inc." I think this is not the answer I was hoping for.

Thanks.
