SmartPlug with POW (AISIRER, AVATAR) - FengtianGu/Sonoff-Tasmota GitHub Wiki

I got few named Smart Plugs on Amazon with same internal parts.

AISIRER https://www.amazon.de/dp/B07DGH8Y8S

AVATAR https://www.amazon.de/dp/B07D73S72W

Device:

• solid design with 16A Relais
• 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 (relais 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

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
• GPIO13 - Button1
• GPIO15- Relais1

Update from my side

I managed to flash two Aisirer plugs using pre build sonoff 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 relais 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.
