For those who would like to use this with the tuya convert; I get the strong impression that these will not work with tuya-convert. The original plug tries downloading a firmware using a non-secure connection. These plugs try to use https, and that fails with tuya convert. I’ll try to see if I can use stunnel to get them to download a firmware, but If they do proper certificate checking, that won’t work. I’ll post my results here later.
A random certificate with a valid certificate from a private root will not work.
Off course the plug does not have an RTC, so cert based authentication will be a challenge. Therefore they seemed to have chosen to use pre shared key authentication.
The SHP6 tries to connect to a3.tuyaeu.com and sugests 2 cipher suites:
TLS_PSK_WITH_AES128_CBC_SHA256 (0x00ae)
TLS_EMPTY_RENEGOTIATION_INFO_SCSV (0x00ff)
So if they use a PSK it’s probably in the original firmware somewhere.
Nevermind, someone has already figured this out and the newest version of tuya-convert supports the new devices perfectly.

Only just received two SHP7, the double version of this. Won’t have time to poke the serial and stuff for a while, but uploaded some pictures if anyone wanna have a look under the hood before ordering these.

Hope to get it flashed soon:) Flashed, need to get buttons and power meter chip working.
Button shows up in log once, but doesn’t do anything besides show up in log.

works like a charm, thank you.
how can i tune this values?
plug_name: blitzwolf_shp6_04
Higher value gives lower watt readout
current_res: ‘0.00290’
Lower value gives lower voltage readout
voltage_div: ‘760’
I just received a SHP-7 and a SHP-9 (and some more SHP-6’S) I can’t wait to get the ‘7’ flashed, I have to open the ‘9’ to see if it’s also esp based, I really hope so 
Just try it. If it is not esp based, then it would anyway not accept the flash
It worked, it’s tasmotized now, so tomorrow I’m going to see if I can figure out the pins for it. It’s rather nice, 3 plugs, and two usb ports, and as I read it, they should be individually controllable.
Is there an ‘easy’ path for figuring out the pins?
I’ve made a very rudimentary template for shp9 now, and it’s uploaded to the repository.
It only handles the switches, LED and button, and I still have yet to figure out how to get powermonitoring active on this.
HI,
I have a BW-SHP6 15A. I flashed it first with Tasmota. The reading where ok. But I prefer ESPHome. So I used one of the configs here:

Unfortunately, the Voltage and Amperage stay 0?? The wattage is correct. Anyone an idea? Or is the latest SHP6 using a different chip? (BL0937 and is not supported?)
I have had the same problem, the problem is wrong configuration.
i used this https://community.home-assistant.io/t/esphome-blitzwolf-bw-shp6-configuration/113938/12
Thanks, but unfortunately this won’t work either? Could it be that they changed the hardware?
Can you double check this line under the sensor section.
cf1_pin: GPIO04
It has to be 04 and not 14
Aha, That’s the failure! Overlooked! Thanks it is working now ! 
I like the idea of using the red led to show if there is power consumption above a certain threshold!
But does anyone know how to make a binary sensor out of that? Something that would have the value True if power => 10 W for instance, and False if < 10W.
Oh wait I can just comment out internal: true from the declaration of the LED_Red
Hi all.I am a beginner and i have 5-6 BW-SHP6 .i running HA on PI 3 .did a solution for upgrade ower the air software to works wit home assistant ?? that is for me now the only option.
or any link for buying 3d printed flash tool
Thanks
