  • Nice size and form factor - can be used as Sonoff Basic R2
  • There seems to be no unique name for the device in the market. The one I ordered for testing Tasmota was packaged by brand / model Canwing CW-001. Let’s use this naming for all similar devices.
  • Operating the device under the original firmware by use of eWeLink-App shows “Coolkit 0185” as brand / model supported by ESP8285.

Features of original device / firmware:

  • Remote control domestic appliances - a phone with 2.4G WiFi can remote control all domestic appliances through phone app.
  • 1000W large power - adopting a 1000 W power to make operation powerful.
  • Suitable for higher than Android 4.0.
  • Flame retardant ABS shell ensures the safety.
  • PCB equipped with serial standard interface (4 pins RX, TX, GND, Vcc / 3.3 V) and button / momentary switch dedicated to GPIO0.
