Hallo,
sorry i never posted anything on GitHub but I have a question and can't find a solution at this time. I'm a noob and like to control my Garage Door with Siri and Homebridge. My Garage Door needs a pulse to open/close.
I bought the "1 Channel Inching/Self-lockIing Mode WiFi Wireless Switch 5V/12V" from itead.cc and like to use it with the Sonoff-Tasmota Firmware to connect via plugin to Homebridge.

Pictures of the Relay:
img_6187
img_6186

Is it possible to flash the Sonoff-Tasmota Firmware to this relay?
Where do i have to connect my USB adapter or can i just use the build in USB Port?
Where are the RX, TX, GIO Ports on this Relay?

I hope anybody can help me and sorry for my bad english.
Thanks!

You can use Tasmota.
Connect the FTDI to the 4 pin cconector near the relay
One of 2 black buttons must be GPIO0

Hi, my board does not have connected RX and TX to the chip, so I must used wires with needles and connect directly to the chip. TX and RX is 2nd and 3rd from to left corner. And be aware about changed 3,3 and gnd pin!!!!! First connect 3,3 and gnd and check without button presing if led go on. Fter that start with pressed button. Then press second button, to have both leds light on. Then you can flas with needles, I had so 70 trys, because my hand shaked a lot ;) P.S. I used autoclick with 20s delay to upload firmware ;)

@tomasroud you say it is possible to flash my relay? Does everything work the way it should or does complications occur?
Is the assignment at the top of the image or do I have to connect 3v3, RX, TX, GND in one of the three red rectangles? If yes, you can tell me which I must use and wich buttons when I must press. Many Thanks!

Eat the elephant by pieces. First locate 3,3 + GND.
It should be GND and 3v3 as in your picture.
Try to connect if LED light up.
Got it? Next step.
Start flash mode ... must both of two LEDs light up.
Next step.
Locate TX + RX.
Try RX and TX on your picture .... try swap TX + RX.
Still not working.
Try on rectangle nr 1 second and third from bottom.
And again try to swap second and third as TX + RX.
Tell how successfull you are. And be aware about switch 3,3 and GND. If you connect bad gnd to 3,3 and connect TX or RX, you just demage your USB programmer. As I twice :(

Press one button nr. 1 or 2, try it and then connect to usb. If lights only 1 led, press next button till both of leds light.

Tell me, how it works.

P.S. When you connect 3,3 and GND, it will be too at bottom two pins on block nr. 3

I use the same arrangement as at the beginning. In the beginning lights still lit. For some reason now lights nothing more when I connect via USB. I do not think this is broken. Can be connected where else GND RX TX and 3v3?

With the normal build in USB of the Sonoff it works perfectly. So the Board is not broken

3,3 and GND are bottom 2 pins in block nr. 3, try it there, if the board will live. Try with ohmmetter that these pins are same as 3,3V and GND.

USB adapter can be broken on TX or RX, on 3,3 and GND probably not. So it must be OK.
If you connect GND and 3,3 is voltage on block 3, bottom 2 pins?

The board lives, that is cool, so, you should connect your USB adaptor to USB in pc in same time as btn. is pressed. Then both LEDs will light ... not flash, light still. OK? P.S. That error means TX or RX is not connected or board is not in fllashing mode (2 LEDs light still)

You must flash with VCC and GND from USB in PINS only. I see you have connected main voltage, it is not possible to flash the device like that. Unplug micro USB voltage, connect voltage in pins and tell me, if you can set up both these pictures too.

Got it finally working!!!
I used Arduino IDE with ESP8285 and Flash Size : 1M (512k SPIFFS) and the latest Sonoff Firmware.
I connect VCC and GND to the pins shown above in the Photo and connect TX and RX (yellow and white cable) to the Pins shown in this picture
31437695-70e1f8be-ae86-11e7-94f3-d6b4c711a761
Hold the jumper cable to this pins without soldering it should work. Try swap TX and RX if its not working. After flashing you have to connect the USB to get into webinterface
For Mac check FTDI Drivers: esp8266/Arduino#3711

This Module is "hard" to flash.

1. Set Up Arduino IDE: https://github.com/arendst/Sonoff-Tasmota/wiki/Arduino-IDE

2. Connect the Jumper Cables to this Sonoff:
   ![1 channel](https://user-images.githubusercontent.com/30130742/35114678-d5cfd596-fc85-11e7-843f-998b104571be.png)

3. Get into flashing Mode: Connect 3.3V while pressing both buttons and than press the bottom one like in this video: https://www.youtube.com/watch?v=E0WBoFCcnYY

4. Upload Tasmota Firmware with PulseTime enabled

You can just hold the jumper cables at the chip pins seen in this video: https://www.youtube.com/watch?v=vzoM4op60jo

Hello
I ordered a similar WiFi module on Aliexpress.

My one has an RF module, besides it seems very similar to Sonoff RF. Of course, it has ewelink software. I would like to reprogram it on tasmote, but I do not know how to enter it in flashing mode. Maybe someone was already trying to flash it? Will you help me?

You are right. I switched mode with second button. Then it works like switch (switching between ON and OFF manually) but when i changed pulsetime, now it is ON only for adjusted time. Great.

Last question i hope:

Is it possible to set power on state to OFF always? I see that with every restart it turns ON for short time (less than 1sec) before it toggles to OFF. You know, i dont want to have the garage door opened after every restart :)

Have same problem. After soft-restart in webui, relay switch 1-0.
After hard-restart (via power on\off) - no problems, relay stay off

hello, please can anyone help me, I have tried every possible combination of wires and button holds as I power on, I am using ESP easy, lol. The Sonoff device is a 1 channel inching type, the serial device is a DSD tech FT232 TTL. I have looked for pin outs for the serial device and can not find, I have tried with the jumper on the RTS and CTS pins and without. I have tried 5v and 3.3V jumpers, I do not think I fried anything yet but the serial board did get a bit hot at first. Everything still seems to light up and at least is not completely dead yet, not even sure which button to hold down so I have tried both seperately. Please see the picture showing 2 boards, I get flash failed every time, so it at least attempts to connect. Orange and yellow are TX and RX, Red is +, brown is ground.

was your USB programmer obviously dead? Just wondering if I messed mine up, it is still seen by Windows, powers up, shows a TX light, but is not flashing the Sonoff inching device.

I wanted to reopen this (it can be immediately reclosed) JUST because I know of no other place to post this valuable information, and in my pursuit of the information I found no other place online where it is properly discussed!!

Here is how to flash your PSF-B01.
NO HARDWARE MODIFICATIONS ARE NECESSARY.
(Note I have the AC/DC 7-32V module and I will be using it as a thermostat override to power on my HVAC fan using Tasmota/HA. This process should work fine for the other version of this module too.)

Use this pinout;

Use this flash boot method (press both buttons while powering it. Both LEDs need to come on.

You can flash Tasmota now.

Once booted, set it to module "1 channel (12)" in the included module list (no external template is needed).

VERY IMPORTANT
SetOption13 1

This will disable the "triple press" functionality that usually reboots ESP8266 into SmartConfig Mode.

After that, you can select via the hardware button if you want inching or locking latch, and you are good to go!

I hope this message saves someone A LOT of time. I took me quite a while to figure out why the module was going haywire.

To teach a man to fish ...
here's what you do. Look up the labeling on the ESP chip (or any of the others), and see their pinout. That's how you can follow where power is coming in

To fish for a man......(happy to save you the time)
LD01-- that is your 3.3 volt regulator. to be absolutely certain I would want to know the labeling on that device so you can verify the pinout, but I am 90% certain that the large metal contact (near label C17) is going to be your 3.3v output(along with one of the three legs, probably the middle one from my experience with thse regulators). So grab your multimeter, stick the black lead onto the casing of that USB connector (we can assume that iwll be ground across the board), Plug a USB cable in, and probe both that big contact and the little one in the middle of the three. If you get 3.3v , follow that to a convenient place to solder or just connect to the small tab temporarily(what i'd do).

Ground is even easier to find--- it will also be one of the three LD01 legs. From the photo I'd bet its the closest to the bottom.. .and connecting to the ground plane. You can use your meter to find 3.3v between your now-known 3.3v pin on that device and one of the other two small legs. You can just connect the ground right onto that chip too (with your 3.3v FTDI. If you are using a 5 volt you'll want to connect the 5v to U4 instead). Highly recommend you verify your measurements match the pinout datasheet, just to double check yourself.

Hope this helps!!

You may already know, but you also need to get the ESP chip into boot mode, which may require grounding of some of the GPIOs. Try it by just using the GPIO0 button held during boot, first. If that doesnt work you may wnat to look up the pinout of the particual ESP you have on there and see what it needs. I have seen ones that ned more than GPIO0 ... like 15(?) also grounded at boot. It also depends what is wired to it on the board itself (I had to cut a trace and then repair it later to get it to flash).

You shouldnt have much trouble finding this info out there in the web! Let us know if yo uneed more assist

95FB4194-0069-45DE-A919-7D1B6DB05445

Ok then that may be ground (and I stand corrected!!). Or maybe the USB outer casing isnt actually board-wide ground.

Next, measure between two of the three smaller pins... all three combinations one at a time
(make sure you are in DC volts mode and not OHMs.. and DONT short any pins accidentally!)

Do you measure any voltage there? You sohuld see 5v and 3.3v there. You really have to, or maybe your meter is broken or not set correctly (or else the board wouldn't power up at all ---- as both the ESP8285 and the LED you see there are powered with 3.3v that must originate from that regulator chip--- whether you power the board with USB or with an outside voltage source, it still comes from there.)

If still having an issue, use another multimeter. And can you make out the labeling on that regulator? If it is AMS1117 its the same chip I use for all my custom made ESP projects..... (and the same one I've seen on sonoffs). Its pinout is always this (bottom right). INPUT will be 5v in this case, OUTPUT is 3.3v

I confirm! It's an AMS 1117. The GND is pin number 3 of my photo.
3--->1 =5v
3--->2=3.3v
3--->A=0
3--->B=3.3v
3--->C=0
3--->D=0
3--->E=3.3v
A--->1=5v
A--->2=3.3v
Can I therefore say that A is the GND and B is 3.3v?

@ryaske ryaske commented Nov 15, 2019

Well, 1= 5v, 2= 3.3v and 3= ground. This matches the pinout I posted above (but you are using numbers in reverse, nbd).

With that said, I would be cautious about assuming anything about ABCDE. Not sure you are certain that one of those is not just "pulled high" by the ESP chip, or if it is actually tied to pin 2. Same for the 0v readings, is it connected to GPIO and just pulled low at the time you're measuring, or actually tied to ground? Cant be sure of that from what you tested so far

What you would do to verify that is either--- break out a bagnifying glass and very carefully follow the traces from the pin #2. Does it go to A B C D or E?

Yoiu could also flip your multimeter into continuity mode (it either makes a beep or reads 0ohms when both probes are touched together), make sure your board is unpowered, and probe pin 2. Do you get zero ohms to any of the letter pads? If so, and you can see a trace that goes direct between the two-- only then would I say you are good to use the letter pads. Otherwise, just tack a wire onto pin 2 for your 3.3v+ and pin 3 for your ground. Those we are certain about already!

Though, A def seems like a ground pad. The square pad itself tells us that too.

C--->3 =Beep (1 and 2 No)
D--->3=Beep (1 and 2 No)
E--->2 =Beep (1 No)

Where you ever able to get this board in flash mode? I for the life of me can't get it to boot in flash mode.

I have tried the button hold down method, and when that didn't work I assumed they aren't connected to GIO0, so I tried grounding what I believe to be the GIO0 pin on the esp itself

Indeed, I received the same new version of this Sonoff and was able to flash it with Tasmota, after powering it on while pressing on both buttons. Below the connections:

Last question i hope:
Is it possible to set power on state to OFF always? I see that with every restart it turns ON for short time (less than 1sec) before it toggles to OFF. You know, i dont want to have the garage door opened after every restart :)

Have same problem. After soft-restart in webui, relay switch 1-0.
After hard-restart (via power on\off) - no problems, relay stay off
Absolutely the same behavior. Any workaround?
