I purchased these TanTan Smart electrical outlets with the hopes of finding an esp8285 or esp8266 within them. When I opened one up I was greeted by something different, and am trying to determine what it is before exploring further.

The model numbers and QR code on the chip have turned up no results: enter image description here enter image description here

Exploring the rest of the smart socket I'm presuming the chip is a combined Wifi + Microcontroller + ROM, as the rest of the product appears to be simple components--a relay to switch the power, a switch and LED for user input/output, and a handful of capacitors, resistors, a thermistor, etc--no other ICs or chips.

The keywords I've tried are things like:
Model: WP3-B
2.4ghz WiFi WP3-B T201-V1.0

None have provided any relevant results. So, I'm hoping to get an identification, or at least a strong lead. What chip is this?

PS: Here's a peek at the rest of the product

    \$\begingroup\$ It's probable that the module is not listed in the internet (not so rare with large manufacturers). That said: can you decode the QR Code? And also can you remove the sticker and make a photo of what's under it? \$\endgroup\$ – Jan Dorniak Nov 3 '18 at 19:17
  • \$\begingroup\$ Also can you trace the other end of those RX/TX wires? It should have another IC, possibly an MCU. \$\endgroup\$ – Jan Dorniak Nov 3 '18 at 19:18

    \$\begingroup\$ what is the MAC address? \$\endgroup\$ – Jasen Nov 3 '18 at 19:20

    \$\begingroup\$ The QR code is the serial number \$\endgroup\$ – Passerby Nov 3 '18 at 20:36

Trick question... it turns out it is indeed an esp8285. I carefully removed the heatshield and found the MCU clearly labeled:

  • \$\begingroup\$ it is an ESP-01M \$\endgroup\$ – Juraj Nov 3 '18 at 22:05
