Just put 1 Sonoff with ESPEasy r78 on it, on a external Light, will see how many time this will stay on the same cycle.

Actualy there is my record :

This one of my first ESP8266 sp1, this module is use for Swiming pool Temp (ds18b20), and Water Pulse Counter (Itron Hall System), there is no condo

, using various power supply because there is no 230v near this place (230v ->12 4A->3.3V)

Back to this new ESP Gadget !

My first project with this, is to bring wifi to this :

Goal is :

- Drive this light via is own on/off switch
- Drive this light via Sonoff relay
- Get Switch Statut

Drive the light via Sonoff relay is ok :

Code: Select all

http://<ESP IP address>/control?cmd=GPIO,<pin>,0

http://<ESP IP address>/control?cmd=GPIO,<pin>,1

Getting switch status is ok by using serial gpio.

Now, i need to drive the physical relay by the physical switch like the sonoff module do as original (without going to my home automation and come back to the light) some thing like a rules :

If switch gpio change to 1 and gpio 12 = 0 then gpio 12 = 1
if switch gpio change to 0 and gpio 12 = 1 then gpio 12 = 0
If switch gpio change to 1 and gpio 12 = 1 then gpio 12 = 0
If switch gpio change to 0 and gpio 12 = 0 then gpio 12 = 1

Did you have any tricks please ?

I used the new R91 release with rules to control the Sonoff relay with the button and get feedback from the led:

Code: Select all

on SW_1#Switch do
  if [SW_1#Switch]=0
    gpio,12,0
    gpio,13,1
  else
    gpio,12,1
    gpio,13,0
  endif
endon

Good news for those who do not like to have 220V near the ESP .

Itead has a newer SonOff switch for low voltage. https://www.itead.cc/sonoff-sv.html. It just needs an external voltage between 5-24 volt DC.
The good news is that more GPIO pins are easy available on this board. GPIO-4, GPIO-5 and GPIO-14 are connected to headers.
As was in the 230V version the relais is at GPIO-12 and a pushbutton on GPIO-0 for easy flashing.
The flash memory is 1Mbyte so perfect for OTA.
The price is the same as the high voltage version $4.85 ex shippingcost

This is a perfect device for ESPEasy

Hi,

Sonoff together with Espeasy is a really great tool ! I bought 9 of them and installed them at home to control my heaters using the French "fil pilote" and Domoticz. I use R82 version for now, I plan on upgrading quite soon.
They work perfectly. I also installed on a few of them a ds18b20 temperature sensor. However, I haven't managed to make them work them using GPIO-1 or GPIO-3.
As a quick work around, I used GPIO 0 which already have a pull up.
To connect easily to GPIO-0, there is a quick fix using solder to expose GPIO-0 on the rf headers.
Have anyone of you managed to connect 1wire devices to GPIO1 or GPIO3 ?

Anyway, I plan on using another sonoff with espeasy to control my water heater and check my power consumption.

I install ESPEASY mini r78 on it, this provid aviability to use GPIO 0 or GPIO 2.

On R91 there is option :

Use Serial Port :

Don't test yet if this allow the same as ESPeasy mini

Edit : Just test to unmark : Enable Serial Port, It Allow aviablility to use rx and tx as "normal" GPIO

Hi,

I tried a configuration for my Sonoff using a combination of Devices, Rules (R94) and an addition to the commands for ESP-Easy to get the following features:

press switch for less than 1 second: turn relais on
press switch for about 3 seconds: turn relais off
press switch for about 7-8 seconds: start access point of esp to recover from mis-configuration

Maybe this is helpful for anybody...
Rules:

Code: Select all

on sw1#Switch=0 do
  timerSet,1,1
endon
On Rules#Timer=1 do
  if [sw1#Switch]=0
    timerSet,2,2
  else
    gpio,12,1
  endif
endon
On Rules#Timer=2 do
  if [sw1#Switch]=0
    timerSet,3,5
  else
    gpio,12,0
  endif
endon
On Rules#Timer=3 do
    wifiap
endon

addition to file command.ino
(insert somewhere after other wifi commands, eg after line 242 "WifiDisconnect"...)

Code: Select all

// --> disconnect current Wifi and restart AP mode
   if (strcasecmp_P(Command, PSTR("WifiAP")) == 0)
  {
    success = true;
    WifiDisconnect();
    WifiAPMode(true);
    //ESP.reset();
  }
 // <--

I'm wondering why you configure an output as an input? Is there a specific reason to?

You`re right. It´s completely unnecessary

Was my error to think it´s needed to use it in domoticz. It´s not...

If you need to read the relay control port level in your rules, you do.

Hi,
I got 3 sonoff with 5 pin, tried to flash one with espeasy.
Always get this error:

Hi !

I have the same problem, is it possible to flash it with a serial port RS232 ?

cherowley · #93 Post by **cherowley** » 08 Apr 2016, 10:13

5 pins?

Ooo, please take a picture

Deennoo · #94 Post by **Deennoo** » 08 Apr 2016, 10:39

Maybe like H801 module one pin have to be set on gnd before power it, to set it on "programmation mode"

i tried to change it the way that the relais status instead of the switch is read, so i could toggle always, even if the relais is switched from somewhere else

Now I have to push the button several times till it changes the state, any suggestions ?

Hi,
I managed to flash the ESPEasy_R78_1024.bin image.
But now i am not able to flash a newer version OTA.
Not even to do a config with the R78.
I can see in the log that the config is saved into the Flash, but when i reboot my sonoff, it starts again in AP mode with the initial setup.
What to do here?
Regards
Hubert

Hi guys !

Thank you for your reply !
First of all there is my photo of the sonoff with 5 pins

But secondly : I can't fly my module with ESPEasy

- I use esptool
- I want to use this firmware : ESPEasy_R78_1024.bin

I got this error :

Connecting...
Erasing flash...

A fatal error occurred: Invalid head of packet

Any idea ?
Is there a way to put the module in firmware update mode ?

Regards

morle · #103 Post by **morle** » 13 Apr 2016, 14:12

Hi,
I have done it this way. In advance i created a R99 Release file with my IDE and flashed it as described here:

I also have this 5pin sonoff device (arrived today) .
Try to flash it using the flashtool (R78) , but can't get it working.
I als changed the FTDI adapter, but

Code: Select all

trying to connect
        flush start
        setting serial port timeouts to 1 ms
        setting serial port timeouts to 1000 ms
        flush complete
        espcomm_send_command: sending command header
        espcomm_send_command: sending command payload
        read 0, requested 1
warning: espcomm_sync failed
error: espcomm_open failed
Press any key to continue . . .

Already changed the RX/TX , tried : disconnect the 3.5V and pushed the button / start the flashtool filled in com port + 1024 + 78 pressed the button and press enter / disconnect the USB press the button start the tool put in de USB again and release the button --> but nothing happens.
What did i do wrong ?

also tried this way https://www.domoticz.com/forum/viewtopi ... 670#p78420

Hi guys !

@Cosmic Gate :
- I exactly have the same problem as you with this 5 pins module,
I tried with the Windows command line tool and with Linux python too but have the same result on each OS.

@Morie :
- do you have this new 5 pins Sonoff module or 4 pins ?
- For watching the wifi network ESP0 do we need to plug the module on 220v or 5v works also ?

Regards.

Works good with a decent 3.3 volt supply on the pins (not your interface 3.3 volt)

Take care of yourself (and your interface and your computer) and NEVER work on the device with 220 volt.

I only have experience with the 4_pin sonoff, but from the documentation i cannot see any difference in the schematics of the 4_pin or 5_pin Sonoff module, (except for that one extra pin), so the procedure to flash it should be the same I think.

Disconnect power
connect your FTDI USB/Serial interface which is set to 3.3 volt.
then while the power is still disconnected push the black button on the sonoff and while keeping it pressed connect the FTDI to the USB port so the Sonoff gets powered.
This shoul force the ESP/Sonoff into flashmode.
Now you can program it with the Arduino IDE or a flash program.

edit:
advisable settings in the arduino IDE:
Board: generic ESP8266 module
Flash Mode: QIO
Flash Frequency: 40MHz
Upload using: Serial
CPU frequency: 80MHz
Flash Size: 1M (64k SPIFFS)
Reset method: ck
Upload speed: 115200

You must get some messages when flashing with the IDE. No result would mean your USB is faulty.

I ordered 2 of the new 5pin-Versions, flashed them both without any problems
I used a cheap 3.3V-Adapter, directly connected, incl. power supply
I connectected GND, RXD and TXD, then hold the button, plug 3.3V, release button

Hi,
I did the same, but after the next OTA update it makes my sonoff unusable.
It worked with R78 which i flashed with the flash tool and then with R99, but flashing R100 OTA makes it unusable.
Can't get it to work again.
My guess is because off this:

Hi everyone.

The work here is excellent and I've had a few of these devices for a while on their dedicated app. Can someone point me to the binaries of the latest 101 version so I can use the rules features. I've tried to build them myself but keep getting compile errors.

Thanks

I believe somewhere along the road of new updates the way ESPEasy writes and saves settings has changed.
The easyest way to solve this sort of problems is to erase the old settings.

1 remove power
2 connect RX with TX
3 reconnect power and wait one minute so the old settings can be erased.
4 reset or disconnect/reconnect power
5 most likely you have to connect now to the AP at 192.168.4.1 where you must choose the wifi network to connect to and fill in the password.
6 connect to the ESP now via the network to the given IP, or check your router to see what IP is given to the ESP.

There is no rule what color when flickers, depends how the manufacturer connects , if any, leds to the chip.

Usually during upload/flashing one led (often a blue one) is flickering very fast which means uploading is busy.
The Sonoff does not have a led that signals a status but the USB/Serial converter shows fast flickering for a while (20-30 seconds) when uploading takes place.
When uploading failes the same led will flicker but just for a short while (1 second or so)

finally got it working ! U used the shorting solution : http://tech.scargill.net/more-sonoff/

is there anyone who can tell the GPIO for the LED on the sonoff ? (in the 103 software you can set the GPIO for WiFi , so would be nice when the LED on the sonoff can be used for it)

Hi Cosmic Gate,

Can you explain your method for flashing your 5 pins module.

You shorten the points with a cable and took it off before flashing ?
Which version of Esptool and ESPEasy have you used ?

Regards.

There is a powersource on the board, I hope it is a decent one

After flashing remove the ftdi connection, and use the powersource on the board
The FTDI has not enough power to drive this board
But as always with 220v, If you are not sure what to do, do not work with it.
220 v can kill you

There is a powersource on the board, I hope it is a decent one

After flashing remove the ftdi connection, and use the powersource on the board
The FTDI has not enough power to drive this board
But as always with 220v, If you are not sure what to do, do not work with it.
220 v can kill you

Hello,
connected gadget to 220V, connected SI temp sensor on sda - pin 4, sdl pin5, 3v3 and gnd, and powered up. - still same problem on I2Cscann gives me errors:
Unknow error at address 0x1
Unknow error at address 0x2
Unknow error at address 0x3
.
.
.
Unknow error at address 0x7e
Unknow error at address 0x7f

strange, I disabled in advanced config in espeasy SErial port, and used PIN1 & 3 for I2c, and this is working... so there must be some problem with pins 4&5 on the board...
