This is old thread, but in case anyone searches…
A lot of the later Tuya devices will have patched firmware and tuya-cloudcutter will not be able to exploit OTA now.
I bought a 2-pack of those WiFi Remote Control smart outlets that are branded as “Prime” but look same as the Feit ones. Was $11.99 CAD on sale. They are firmware 1.1.15 which is not exploitable.
I think tuya-cloudcutter is good for old/existing devices that one may happen to have around and want to exploit, but I would not recommend buying any Tuya device just to re-flash with ESPHome or Tasmotoa etc. - there are better options. The hardware is also junk… .when I took one apart to examine the chip, the hot wire fell off and I had to resolder… wires not even tinned, looks like was welded onto the AC receptacle. Being an outdoor plug that could get banged around, this wire could have broke off and caused hazard. Returning to Costco.
