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
Smart Plugs from 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
- 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 (relais also works)
- test mode works with 5 or 3.3 V (relays also works)

* in Platformio for tasmota flag change from 1MB to 8MB is needed, otherwise flash fails.

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)

**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). The detailed procedure can be found at https://github.com/arendst/Sonoff-Tasmota/wiki/Power-monitoring-calibration

## 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.
## 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
