SmartPlug with POW

Smart Plugs from Amazon with same internal parts: - AISIRER - AVATAR


  • solid design with 16A Relays
  • 8 MB memory chip
  • 2 LEDs
  • POW function (unfortunately did not test yet, need help)
  • very small size, easy to disassemble
  • no need to disassemble PCBs
  • test mode works with 5 or 3.3 V (relays also works)

Disassemble * take off the lead with 2 screws * put small cross screwdriver inside 220V plug connector, there are 2 screws * free the antenna from plastic (no need to disconnect) * pull of PCB from the case

Important build flags. * in Platformio for Tasmota flag change from 1MB to 8MB is needed, otherwise flash fails. build_flags = ${esp82xx_defaults.build_flags} -Wl,-Teagle.flash.8m.ld
* in Arduino IDE: board selected - "Node MCU 1.0", standard

Found how some of PINS are linked to main PCB and are easy to connect for flashing



I've decided to use 5V - there is a painted pad on the PCB, clean it and attach 5V (see image) * Connect GPIO0 to GND * Connect RX, TX * Connect 5V and GND * Connect USB to PC, start flashing

Tasmota WEB config (Generic) * GPIO0 - Led1i * GPIO2 - Led2i * GPIO5 - HLW8012 CF * GPIO12 - HLWBLSELi * GPIO13 - Button1 * GPIO14 - HLWBL CF1 * GPIO15- Relais1


IMPORTANT: in order to have an accurate measurement of Voltage/Current/Power, you have to calibrate the internal meter with a well know load (like lamp or hair dryer) using this detailed procedure.

Update from my side~

I managed to flash two Aisirer plugs using pre-compiled tasmota.binaries, since my plugs had only 1M flash. I used 3.3V connected directly to the ESP board. I had some trouble with WLAN connectivity which caused the relays to pulse, so I switched to 2.3.0 core, which seems default again since a few releases. This runs quite well. Configure as BlitzWolf SHP(45) Module and also the power measurement is working.

Update from nos86~

I have updated the guide in order to interface Tasmota with the power meter inside smart plug (tested only on AISIRER) and added the link for the power monitoring calibration
