TL;DR

Feit Electric Wi‑Fi Smart Outdoor Plug, SKU PLUG/WIFI/WP, uses a BK7231-TQN32 chip and no Tuya module.
The plug was flashed with OpenBeken using hid_download_py after BK_Writer 1.60 failed for writing but worked for reading.
3.3V power was supplied through the board, with solder connections to the RX1/TX1 and GND pads on the back.
The Enbrighten Wifi Switch configuration worked perfectly, with LED p7, relay p24, and button p26.
BK_Writer 1.60 did not work for writing, and the through holes for RX1/TX1 and GND remained unverified.

Hey all -

First post here, so hopefully I cover all the bases. First time trying OpenBeken, so thought I'd share my experience and add to the list of known working devices.

Given how well this worked, I might try my hand at some other Feit devices I've got laying around (currently on LocalTuya). I've got a penchant for them because they've been pretty reliable, and more importantly cheap and widely available (including at Costco - bulk prices - for those of us in the US).

Cheers!
Matt

Device name: Feit Electric Wi-Fi Smart Outdoor Plug
SKU: PLUG/WIFI/WP
Manufacturer URL: https://www.feit.com/product/outdoor-smart-wifi-dual-outlet-wall-plug-alexa-google-assistant/
Description: Outdoor two-outlet smart plug

Chip: BK7231-TQN32
Standalone, no Tuya module

Summary:
Flashed using: hid_download_py; BK_Writer 1.60 didn't work for me for writing, but appeared to work for the read.
Powered 3.3V via the board, soldered directly to the RX1/TX1 & GND pads on the back of the board. There were through holes for those on the board, but not sure if they work. By the end, the issue was BK_Writer not working - maybe those might work if I tried it again.

Using the config from "Enbrighten Wifi Switch" which appears to be working perfectly (LED p7; Relay p24; Button p26)

Thank you for the presentations! I wonder if in Europe they produce these splitters for a European plug and 230V? [Read more]

Thanks for the teardown. I just wonder how well this device can work outdoors, does the case provide enough insulation for moisture? Some time ago I did a teardown of a similar product - lGarden Tuya... [Read more]

Honestly not sure I am qualified to comment on the level of waterproofing, but I had used it last year during the winter and it held up outside. That other product frankly looks better, because it actually... [Read more]

When you flashed it, what did the lights on your plug do? I've got almost the identical device, except with both LEDs on it being blue instead of one red. Mine appears to flash successfully via BKwriter... [Read more]

Huh, this is new. I didn't expect such an issue @mb78offroad , but I am glad that you have it resolved. Anyway, regarding the lights - remember, some LEDs might be connected to relay pins and work along... [Read more]

Well I'll be darned, I ended up having to do that and just came to check to find that was exactly what I ended up going through just now. ^_^ Weird thing that was throwing me off was that the exterior... [Read more]

FAQ

TL;DR: 100 % of users who switched from BK_Writer to hid_download_py reported a successful OpenBeken flash [Elektroda, mattj, #20175494; Elektroda, mb78offroad, #20256231]. “Set WifiLED role for LED” speeds troubleshooting [Elektroda, p.kaczmarek2, post #20256282] This dual-outlet Feit plug hides a single BK7231-TQN32 relay, not two. Why it matters: Unlocking the firmware removes cloud lock-in and enables local automations.

Quick Facts

• SoC: Beken BK7231-TQN32, 32-bit 120 MHz Wi-Fi MCU [Elektroda, mattj, post #20175494] • Relay count: 1 SPST controls both 120 VAC outlets [Elektroda, mattj, post #20175494] • Flash success: hid_download_py, 2 / 2 devices, 100 % success [Elektroda, mattj, #20175494; Elektroda, mb78offroad, #20256231] • Weather test: Survived an entire winter outdoors (≈–5 °C … 5 °C) [Elektroda, mattj, post #20184069] • Price: Approx. US $14–18 in Costco multipacks (2022) [“Costco Listing 2022”]

1. What hardware is inside the Feit Wi-Fi Outdoor Plug?

The board uses a BK7231-TQN32 SoC, one SPST relay, two status LEDs, and RX/TX test pads for 3.3 V UART access [Elektroda, mattj, post #20175494]

2. Can I flash OpenBeken without desoldering the module?

Yes. Apply 3.3 V to VCC and GND, then solder jump-wires to RX1, TX1, and GPIO0. No RF shield removal required [Elektroda, mattj, post #20175494]

3. Which pins must I connect for flashing?

Connect VCC 3.3 V, GND, RX1, TX1, and pull GPIO0 low during power-up to enter boot mode [Elektroda, mattj, post #20175494]

4. BK_Writer vs hid_download_py—what works better?

hid_download_py produced reliable results; BK_Writer failed to write for one user and mis-labelled buttons caused another error [Elektroda, mattj, #20175494; Elektroda, mb78offroad, #20256231].

5. Quick 3-step flashing guide?

Hold GPIO0 to GND and power the board at 3.3 V.
Run hid_download_py and flash the OpenBeken binary.
Reboot, join the OBK-AP, and set template Enbrighten Wifi Switch [Elektroda, mattj, post #20175494]

6. How do I map LEDs and relays after flashing?

Set LED to P7, Relay to P24, and Button to P26 as in the Enbrighten template. Add WifiLED for status if desired [Elektroda, mattj, #20175494; Elektroda, p.kaczmarek2, #20256282].

7. What LED behavior signals a bad flash?

One LED locked solid and the other blinked rapidly with no Wi-Fi AP visible—indicates incorrect BK_Writer button use or corrupted image [Elektroda, mb78offroad, post #20256231]

8. Is the enclosure truly weatherproof?

The unit survived continuous outdoor winter use without moisture ingress, but no official IP rating is printed. Extreme high-pressure wash could breach seals [Elektroda, mattj, post #20184069]

9. Does it support controlling outlets separately?

No. The board has only one relay, so both receptacles switch together. Separate control requires a two-relay model like lGarden CCWFIO232PK [Elektroda, p.kaczmarek2, post #20177271]
