Blitzwolf BW-SHP6

#1 Post by Wiki » 23 Jan 2019, 18:36

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 :(

Best Regards,
Robert

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.

ESP Easy Webdumper [easy screendumping of your units]
ESP Easy Netscan [find units]

Sponsor ESP Easy, we need you :idea: :idea: :idea:

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 :D

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 :)

@Wiki

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.

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
