Blitzwolf BW-SHP6

[Wiki]

Today I received two of these devices: https://www.banggood.com/BlitzWolf-BW-S ... rehouse=CN

I ordered them just for curiosity. After having managed to flash them using 1M flash size ESPEasy release normal dated on 2018-12-31, I got a fan of them. They are small, able to switch 2300W, both LEDs are uncoupled from the relais, so you can use them for messaging different states, energymeter onboard. The first I have already in production - working pretty well.

The configuration I have figured out is: GPIO0 - LED red inverted. GPIO2 - LED blue inverted, GPIO13 - Switch, GPIO15 - relay

I took the same configuration and rules for relay and switch like the ones for SONOFF devices, except the GPIO ports.

The chip for energy metering should be the HJL-01 or the BL0937 as I read in the sources of tasmota. Is there any chance to include this chip in a minimal relase for being able to use OTA?

Aditional info:

I have found the pinout of the ESP used in this smart plug here: https://github.com/arendst/Sonoff-Tasmo ... template.h

Just search the file for Blitzwolf.

I am sorry, but my coding skills are not good enough to start programming by myself.

Something can move forward in this topic? Is there a chance for a dedicated ESP Easy firmware?

There is only the hard_SONOFF_POW version, but you need 4 mb of flash. BW-SHP6 has only 1 mb

We're building a portal that will be paid access only in order to get some proper income. Currently both me and TD-er is starting up our own businesses which takes some effort. Once the portal is up and running we hope to get some more traction in terms of sponsorship from the community = get 100% time to spend in ESP Easy.

So in short, that is what's needed for more attention.

Due to the fact that I am one of your patreons and that I love espeasy I can understand your answer - you have a pretty ambitious goal and my respect.

But its a pitty that one has to change to Tasmota for using these very useful devices. The BW-SHP2 e.g. is able to switch 3.6kW (!) and is therefore able to serve a dishwasher and delivers all the energy data you need for a real smart home - as well as the BW-SHP6. The only difference is, that the BW-SHP6 is only able to switch 2kW like the SONOFF S20.

Hopefully it will come. Let the guys do their thing in improving quality & structure. You can always re-flash when time comes

I changed the flash from 1MB to 4 MB (Winbond)
I used a new flash for SonOFF (ESP_Easy_mega-20190301_hard_SONOFF_POW_4M.bin)
And it works

You can use normal ESP8285 bin file.
Configuration fot Blitz is described in TAsmota wiki:

GPIO_LED2_INV, // GPIO00 Red Led (1 = On, 0 = Off) - Power status
GPIO_USER, // GPIO01 Serial RXD and Optional sensor
GPIO_LED1_INV, // GPIO02 Blue Led (1 = On, 0 = Off) - Link status
GPIO_USER, // GPIO03 Serial TXD and Optional sensor
0,
GPIO_HJL_CF, // GPIO05 BL0937 or HJL-01 CF power
// GPIO06 (SD_CLK Flash)
// GPIO07 (SD_DATA0 Flash QIO/DIO/DOUT)
// GPIO08 (SD_DATA1 Flash QIO/DIO/DOUT)
0, // GPIO09 (SD_DATA2 Flash QIO or ESP8285)
0, // GPIO10 (SD_DATA3 Flash QIO or ESP8285)
// GPIO11 (SD_CMD Flash)
GPIO_NRG_SEL_INV, // GPIO12 BL0937 or HJL-01 Sel output (0 = Voltage)
GPIO_KEY1, // GPIO13 Button
GPIO_NRG_CF1, // GPIO14 BL0937 or HJL-01 CF1 current / voltage
GPIO_REL1, // GPIO15 Relay (0 = Off, 1 = On)
0, 0


So you can without any problem switch relay and change LED status with normal ESPeasy firmware.

You can use normal ESP8285 bin file.

but in this file you do not have the HWL8012/BL0937 module

Eehm, how did you add a 4M Winbond to a 8285 which is as far as I know the chip of the Blitzwolf? Do you have something like a picture?

@kimote: thats exactly what I did before I opened the thread

Disassembly process:
https://github.com/arendst/Tasmota/wiki/BlitzWolf-SHP6

Replacing memory process:

1. Remove old memory


Old memory:


2. Mount new Winbond memory (W25Q32BVSSIG W25Q32 W25Q32B 25q32 W25Q32BVSIG 25Q32BVS)


3. Where to buy memory ?:, for example:

Cool. As I can see, there is a 8266 inside instead of the 8285 I have read about somewhere.

Thank for sharing.

Hi everyone, I would like to know if I can use them now too. I think this can be a very good investment but I'm a little afraid to invest money and obtain nothing. You know these days I'm very careful about the investment that I'm making. You know I would like to invest some more money in order to develop a business. I even started to look for some ideas and found this site themoneymix.com. There I read more about investments and how to invest correctly in order to obtain an income. Also, I found some ideas there. So what d you think does this still work?

You can use them, but they are quite hard to flash.
Also I would not use these for currents more than a few ampere.
The Sonoff POW series are maybe a bit easier to flash as the pins needed are better reachable and the POW series have larger flash memory which makes updating them a lot easier.
Same warning about max. current applies for the Sonoff units though.

I've got a question about the Blitzwolf BW-SHP6, which version of ESPEasy should I use if I want to make use of all the possibilities of this smartplug?

According to the Plugins page, the plugin for power measuring HLW8012/BL0937 should be in the 'ENERGY' builds.

[TD-er]

I think you have to check the flash size of those units first.
I don't think it will have 4M flash.
