Support of Sonoff Dual R2 variant #1249
Comments

since you have found what's connected to what, you should be able to use the
wemos module type and define the various GPIOs
|
|
As far as I see no it will not work 100%. Because the Button1 and the case switch are connected to the GPIO9 and 10, but in the "WeMos D1 mini" the GPIO 6 - 11 are not defined as GPIO_USER. And otherwise in my opinion if this is an official Sonoff device then is should be supported by default. |
|
The R2 will be included in Tasmota as a seperate device. For now I use your findings regardiog GPIO and add it to the next (pre)release. Edit: The GPIO connections are based on the 4CH where button 3 is the one on the casing. I guess I configure button 1 and 2 as switch 1 and 2 and button 3 (GPIO10) as button 1. Let's see if that's useful... Edit2: Like this: |

* Add read
temperature retry counter (#1215)
* Fix lost sensors by performing
sensor probe at restart only thereby removing dynamic sensor probe

The best thing I can see in this new version is that they have finally stopped using the fuse clips that were quite incapable of handling 16A. Have a look here for tales of woe when trying to use the fused Sonoffs with high currents: http://support.iteadstudio.com/support/discussions/topics/11000012976?page=1 |

@arendst still no documentation. Way to go 💯 |
Add support for Sonoff Dual R2 version All possible inputs are defined as USER configurable. Case button multipress support for 2nd relay. Web configuration "BUTTON1" label fix.

For documentation I've annotated previous ESP8285 picture with pinout issued from the Espressif datasheet. I was looking for available GPIO pins. It appears that GPIO 2, 4, 6, 7, 8, 11, 14 & 16 are free but only available on the ESP8285 chip, which requires some squills to solder. Instead of ADC (pin6) it seems that it's GPIO15 that is used to monitor the power supply. [Edith] In the meantime, I just managed to connect a DS18B20 on GPIO1 (TX).

@vanyid I have the same board, How do you flash tasmota firmware? I have the arduino uno, it is the same process as esp8266 but instead of select 8266 generic board I need to select generic esp8285 module?... It is compatible for add external switches? |

Has anyone managed to get an AM2301 to work on the Dual R2. I have tried Button 0, Button 1 ,Tx and Rx and just get NaN as a response.(v6.2.1). Have tried other versions back as far as 5.12 and the sensor doesn't appear in the UI after configuration. |
|
Of course it works. |
|
Hi. I've a new Version with Layer date from 2019-09-04
|
|
Yes I got 4 of them too and they behave the same as v1.0 |
|
Is it possible to use a bme280 over sda and scl? When I look at pcb 1.4 pin 14 is in use |
|
Yes, no problem to use the header on the top of board to connect a BME280 but you'll have to disable SerialLog (it's maybe automatic in Tasmota code).
|

@pmknowles That's a great summary. You should add it to https://tasmota.github.io/docs/Peripherals/#usable-pins |
|
The same exists for ESP32. Perhaps this would be great to add it, too. https://randomnerdtutorials.com/esp32-pinout-reference-gpios/ |
Hello Tasmona community,
I have purchased 3 x Sonoff Dual modules. But those are different from any other mentioned module. (or just I not found anything on the web, maybe my fault) Does anyone have the same board?
The label on the board: Sonoff Dual R2. Ver 1.0 , 2017-7-20 (maybe the manufacturing date)
Inside the case there is only one chip a ESP8285.
The relays and the LEDs are directly connected to the ESP.
I will open a pull request according to the new module as soon as I am able to check in the necessary modifications to my fork repo.
Here is the pinning of the ESP:
This variant is more simpler then the previous one. (and perhaps cheaper for iTead)
Some pictures about the board:
