There’s currently a promotion on Amazon for a pack of four ESP8266 smart plugs that are ETL and FCC certified, and sold for $13.49, or around $3.5 per socket.
In order to apply for the discount, you’ll need to the Amazon product page, tick on “Save an extra 20% when you apply this coupon.”, and enter the coupon code “ABVYP87G“.
Once this is all done the price will be $13.49 shipped within the US. The plug works in the 100-240V range, but when shipping outside of the US, you’ll need to pay extra for shipping and provisions for customs duties.
Gosund WP3 key features:
- 2.4 GHz WIFI connectivity
- Rated Voltage: 100 – 240V
- Rated Current: 10A Max
- AC Frequency: 50/60Hz
- Max power: 1100W
- Operating Temperature – -10 ~ 60°C
If you have no interested in running proprietary software, you’ll be happy to know Gosund WP3 smart plugs are compatible with Tasmota open-source firmware. There are instructions to open the plug and flash the firmware…
but if you don’t feel comfortable open the device and soldering a few wires, Gisund WP3/WP5 smart plug should work with tuya-convert to let you upgrade the firmware without even opening the device. [Update: Sorry, this won’t work at this time, since the firmware has been updated to close the loophole. See comments]
