Sonoff RF Bridge 433 + Digoo DG-R8H 433MHz

[AhmadK]

I have and use Sonoff RF Bridge (hardware modded with OMG Pilight), Digoo R8H, Arduino MEGA(with RFLink) and Wemos D1 mini (with OMG RF).

As far as I know, currently you can not get readings from R8H using OMG, it only works with RFLink.

So if your goal is to use R8H, then you need a board flashed with RFLink and not Sonoff RF Bridge. There are ways to connect RFLink via WiFi as pointed out earlier.

If you don’t care if it’s R8H or another sensor and all you need is temperature/humidity readings via MQTT, you might be better off building something like BRUH sensor - possibly using Wemos D1 mini and flashed with ESPHome (I believe there are plenty of options and guides around). That way you don’t need Sonoff RF bridge as your sensor will use WiFi, not RF signal to transfer data.

Another thing - don’t use Digoo R8S unless you’re going to power it from a power adaptor as it will change its ID every time you replace batteries and it sucks.

Thanks a lot Ahmad for your answer.
But I think is better if we can make work this sensor with OMG for some reasons.

To make it work via WiFi, the RFLink need to much boards for my opinion.
The Bruh sensor is great but it use WiFi power and so is not great to use it with battery
The last reason but same important is that with this sensor work on OMG
I think is good think for OMG community grow

Thanks again

So I make the hardware modification on the Sonoff RF Bridge (mine is R2 V1) :

I downloaded the OpenMQTTGateway_sources and the rfbridge-libraries
and I put all 2 in the ArduinoIde “libraries” folder
I uncoment "#define ZgatewayPilight “Pilight” and I change the pin’s in the config_RF.h
RF_RECEIVER_GPIO 4 and RF_EMITTER_GPIO 5

Now I don’t know witch board I must choose from Tools menu cause if I try to compile it give me the error:

Board generic (platform esp8266, package esp8266) is unknown
Error compiling for board Generic ESP8266 Module.

Thanks a lot for the help
Denis

[denisj]

I have solve all problems with the board under ArduinoIde
but then it give me a lot of error about “libs not found”.

So I read some docs that tell me that is better if I use Visual Studio with PlatformIO.
So I installed all, then I downloaded again the OMG version 0.9.4
then I modified the User_config.h (wifi,mqtt)
then I uncomment the record: #define ZgatewayPilight “Pilight”
then I define t 4 and 5 PIN in config_RF.h
then I click the Build icon…
It give me the error:

Someone can help me please to flash the Sonoff RF ?
Thanks in advance

Would it be possible to test the code below on an esp8266 ?

zoomx/PrologueDecoder/blob/master/PrologueDecoder.cpp

It could be a first step for the r8s integration.

@denisj

So I installed all, then I downloaded again the OMG version 0.9.4
then I modified the User_config.h (wifi,mqtt)
then I uncomment the record: #define ZgatewayPilight “Pilight”
then I define t 4 and 5 PIN in config_RF.h

With platformio you don’t need to modify user_config.h. Just uncomment the env you want to build.

[denisj]

@1technophile

With platformio you don’t need to modify user_config.h. Just uncomment the env you want to build

Sorry but is the first time that I use Platform.io
I have restart all from beginning and I only change the WiFi and MQTT
credentials and settings in the user_config.h
Then I click the build icon… now I’m here from about 20 minutes to wait that finish work.
I don’d understand what it do all this time.

So next step will be to uncomment the env in the platformio.ini file ?
Then… what I uncomment ? the “default_envs = rfbridge” or the “default_envs = esp32dev-pilight” ?
…or all two ?

Thanks a lot again
Denis

@denisj

“default_envs = rfbridge”

The rfbridge does not contain an esp32.

[denisj]

Ok… bu in this case I don’t understand how platform.io understand that I want PiLight

I program it with default_envs = rfbridge and now I can see in my MQTT broker some topics:
home/OpenMQTTGateway_SRFB/SYStoMQTT
home/OpenMQTTGateway_SRFB/LWT
home/OpenMQTTGateway_SRFB/version

But if I push some rf433 remote from my alarm there is no updates in the MQTT.
Maybe it’s work… but I don’t know ?

I think I’m missing something… cause in this blog page you tell us to uncomment the:
#define ZgatewayPilight “Pilight”
in the user_config.h file.

Can you let me know the right way please ?

Thanks a lot again
Denis

[denisj]

Nobody can help me please ?
Thanks

[1technophile]

Here is an evironment description that you should add to your .ini file:

[env:rfbridge-pilight]
platform = ${com.esp8266_platform}
board = esp8285
lib_deps =
  ${com-esp.lib_deps}
  ${libraries.esppilight}
  ${libraries.esp8266_mdns}
build_flags =
  ${com-esp.build_flags}
  '-DZgatewayPilight="Pilight"'
  '-DGateway_Name="OpenMQTTGateway_SRFB_PIL"'
board_build.flash_mode = dout

Once done you can add also the call at the begining of the ini file:
default_envs = rfbridge-pilight

@denisj

I think I’m missing something… cause in this blog page you tell us to uncomment the:
#define ZgatewayPilight “Pilight”
in the user_config.h file.

These are the instructions for Arduino IDE not for platformio.

At final, and to come back to this thread subject I don’t know yet if I’m going to add the R8H to Pilight or RCSwitch or with another way. So you may load Pilight but you would have to reload a different version later.

[denisj]

@1technophile

So you may load Pilight but you would have to reload a different version later.

This is not a problem… the first time is more difficult

Thanks a lot for the piece of source code.
I modified, build and upload the code… and everything was ok until I test it.
But I think my Sonoff RF now it’s broke.
Cause is not work anymore. Not MQTT topics, no WiFi link (cause no ping)
No WiFi manager… nothing.
I’ll need more time to test and understand what’s wrong.
And if I can’t make it work I think I’ll make a new OMG using NodeMcu (cause I have some boards at home)

In your opinion… is better SonoffRF or NodeMCU + radio please ?
And in the mean time… witch radio hardware is best quality in order to linked to the NodeMcu please ?
I’ll buy it and wait to arrive the shipping.

Thanks a lot again

If you are able to upload the ESP is still alive, did you try to erase the flash memory?

@denisj

NodeMCU are easier to upload and update but you will need a box.
RFBridge as a box but is limited by its internal decoder if you don’t modify it.

@denisj

And in the mean time… witch radio hardware is best quality in order to linked to the NodeMcu please ?

You can take the superheterodyne ones linked below (affiliated links) :

OpenMQTTGateway reference sheet compatible devices, parts, functions list, pinout

[denisj]

@1technophile

erase the flash memory

IT’S WORK !!!
…it was “pio run --target erase”

Now in my MQTT broker I receive:
{"message":{"unit":65034,"battery":1,"state":"closed"},"protocol":"iwds07","length":"","repeats":2,"status":2}
…from a remote that I have at home alarm
I receive all the dor sensor, and I received also in Node-Red node test
So it’s like it’s work

The olnly think that I don’t receive is the car gate remote… and I know it’s 433mHz
…but is not the right place here in this thread.

So now I’ll wait that R8H will arrive and I think then I will watch this thread in order
to try to make it work

Thanks a lot for all help… and the future one

Great!

It is normal, most of the time car gate use a rolling code system (at each press the code is different) to avoid hacking. It should feel you safer also

Hello guys

I have 2 Digoo DG-R8H. I can get the proper information using nexus433 on RaspberryPi…
Client mosqsub|30542-paul-Insp received PUBLISH (d0, q0, r0, m0, ‘nexus433/sensor/da01/state’, … (72 bytes))
nexus433/sensor/da01/state { “temperature”: 22.7, “humidity”: 75, “battery”: “100”, “quality”: 66 }

But as denisj, I would prefer to use Open MQTT Gateway with Sonoff RF Bridge.

So, I followed your the instructions in this tread (thanks a lot) and I got my RF Bridge working receiving door sensors but I am not getting the Digoo DG-R8H information…

Did I missed something?
1technophile asking to test code on an esp8266 (PrologueDecoder)
Is this something I should use?

Thanks!

[denisj]

Hi Paul,
1tecnophile promise me that when will find some time in order to test OMG with DG-R8H,
and develope it, he will tell us how to update the firmware of RF Bridge.

Maybe we can help him… but I’m Cobol programmer and I don’t know how to make test.

Thanks
Denis

[paul5]

Hi Denis,

I will be please to help also!
I am DBA and doing a lot of Perl programming for automation…
I am looking forward to learn Python.

The code that 1tecnophile putted for testing, where should it be putted?

[HugoGresse]

Any news? I think the R8S is already working on OMG with PiLight but the the R8H

[1technophile]

@HugoGresse

but the the R8H

On my todo for this summer
