openmqttgateway's Issues

Add the possibility to filter unknown protocols for IR

Add to your code if you like

I have added a DHT11 sensor and ldr sensor to you code and it is working well. Add if you like.

The DHT.h library needs to be version 0.1.13. Doesnt compile right with latest

LDR is wired to A0 with a voltage divider....I used a variable resistor to tweak and did most of my testing on an uno to get max voltage below 1v. This Works very well surprisingly very sensitive. In a dark room i get 0 and the glow from laptop screen is picked up.

DHT11 is going to D6 GPIO12

//Extra Sensors Setup
//Light Reading**********************************************
unsigned long previousLightMillis = 0;
const int lightInterval = 120000;
//Temp Sensor************************************************
#include <dht.h>
dht DHT;
#define DHT11_PIN 12
int inPin = 12;

//Start Extra Sensors in main loop
extraSensor();

//More Sensors

void extraSensor() {

if (millis() - previousLightMillis >= lightInterval) {

//Read Analog Light Sensor
int sensorValue = analogRead(A0);
Serial.println(sensorValue);
previousLightMillis = millis();
String lighttopic = "home/Light";
sendMQTT(lighttopic,String(sensorValue));
//Read DHT Sensor
int chk = DHT.read11(DHT11_PIN);
float temp = DHT.temperature;
Serial.print("Temperature = ");
Serial.println(1.8temp+32);
Serial.print("Humidity = ");
Serial.println(DHT.humidity);
String temptopic = "home/DHT/temp";
sendMQTT(temptopic,String(1.8temp+32));
String humiditytopic = "home/DHT/humidity";
sendMQTT(humiditytopic,String(DHT.humidity));
}

}

json payload

instead of passing parameters into the MQTT subject use json

Problems with Sony IR

I had to change the following code in "ZGatewayIR.ino" from
if (strstr(topicOri, "IR_Sony") != NULL){ irsend.sendSony(data, 12); signalSent = true;

to

if (strstr(topicOri, "IR_Sony") != NULL){ irsend.sendSony(data, 15, 3); signalSent = true;

Because my Sony AVR relies on having IR signals repeated 3 times (this is the last parameter...) and uses 15bit signals...

Maybe you could generalize the function a bit more, or is there a way to tell how many repetitions and which bit-length to use via MQTT?

other ethernet module/library support

Wiki says

W5100 shield (tested) or other ethernet module

I have enc28j60 ethernet module and trying to adapt the sketch to use UIPEthernet library. Hope I'm doing things right...
So, I'm only getting the following:

client mqtt not connected, trying to connect
Attempting MQTT connection...

Will it be possible to provide the sketch for such hardware, even untested? I will be more than happy to test and share results. Thanks!

DHT Enable

Hi,

i have tried to Compile with the option use of DHT but i run in some problems...

first Missing the DHT.h so i installed the "DHT_sensor_libray" from Adafruit
then there was missing the Adafruit_Sensor.h so i installed "Adafruit_Unified_Sensor"

But now i am Ending in:

ZsensorDHT:38: error: redefinition of 'long unsigned int time1'
unsigned long time1 = 0;
^
ZgatewayBT:36: error: 'long unsigned int time1' previously defined here
unsigned long time1 = 0;
^
exit status 1
redefinition of 'long unsigned int time1'

Probally using the Adafruit Libs is wrong and i must Install other ones ?

Sorry i have started a short time ago with all the Arduino things...
And dont have such a good knowlegde in debugging scripts

At all i think it would be a good Idea to Expand the instructions for Adding the DHT libs like it was described for the iremote and pubsubclient ;-)

Hannes

Standing Fan IR Code drives me Crazy

First of all, thank you for doing this great project.

I am new with all this stuff and started with Arduino 2 Weeks ago... let a led blinking and thinked.. ok that was easy so look for some cool stuff and here we go....

I think i made all as you have described including "#define MQTT_MAX_PACKET_SIZE 256"
all codes working fine expect the RAW Code....

I cannot find a Global Caché Code for my Fan
so i have started make my own small code for detecting and sending the codes and endet up with this...

but nothing happens...

looks like there is something wrong... the LED on the NodeMCU is not flashing when send this..
instead when i use:

mosquitto_pub -t home/commands/IR_NEC -m 551494365
for my LG TV, the Led is flashing at send

hope anybody can help me what i doing wrong...

memory fault

I think in function callback: shouldn't it be
byte* p = (byte*)malloc(length+1);
because later you do
p[length] = '\0';

Turn on and off RF trasmitter

Hi,
Is the 433MHZ Tx always transmitting carrier signal even if i'm not trasmitting data?
Is it better to connect TX VCC to a GPIO and turn it on/off?
ESP8266 GPIOs carry 12mA, that should be ok for powering the TX unit.

Add the ability to handle RF codes up to 32bits

Light Sensor Addon is finished

i hope all of you understand my bad english ;-)

sorry for the chaos and unstructured work but this is the first contribution
for a project in my life... i started 3 month ago with the arduino stuff
and have no clue i have understand the git system correct how to merge code..

So here we go....

https://github.com/HannesDi/OpenMQTTGateway/tree/addon-lightsensor

I have opened the Door on OpenMQTTGateway for "i2c Bus Modules/Sensors"
but this has required to complete restructure the Pin Connections
on the NodeMCU

Why?
2 Reasons

First:
As most of us know and and 1technophile has allready written
we run out of usable pins for different boards.
So i have made some research and found out that many pins
could switched its function...
like d0 - gpio16 and d5 - gpio14
d0 could not be used for receive because it has no interrupt as i have understand
so why not use it for Sending IR ? ;-)
the d5 is free and usable for other stuff.

Second:
To Use I2C there a 2 possible ways...

1. complete re-invent the i2c software for the Board
2. use the Wire.h that exists and work great...
   But Wire.h has a small problem.. it explicit wants D1 and D2 on the ESP8266
   and so i have freeded and switched the other pins..

Ended up in this:

D0 - GPIO16 # as Send Pin for IR (because IR need no interrupt)
D1 - GPIO5 # as SCL (I2C Bus) for BH1750 Light Sensor
D2 - GPIO4 # as SDA (I2C Bus) for BH1750 Light Sensor
D3 - GPIO00 # as Receive Pin for 433mhz
D5 - GPIO14 # as Receive Pin for DHT22
D8 - GPIO15 # as Send Pin for 433mhz

And all is Working ;-)

There is a another benefit for using this...
I await the next 2 Days a another i2c bus module the "BME280" a "I2C or SPI Temperature, Humidity and Pressure Sensor"

for all they dont know what this means...
the I2C bus can handle up to 8 modules on 2 wires in parallel (no more worries about free pins)
and... for thoose they have allready a DHT11 or DHT22 you can unplug it then and
we have again pin D5 free for other things ;-)

i hope you an first of all 1technophile like my work

Best Regards Synologix / HannesDi

Add the possibility to pass raw data to and from mqtt from and to IR

so as to extend the range of compatible devices

esp8266 open wifi network

The esp8266 is visible as an open wifi network with a SSID like ESP_12345. It is possible to connect to it and get an ip-number.

To avoid this, you can set the esp8266 in station mode:
In OpenMQTTTGateway.ino add, after line 146 delay(10) :

WiFi.mode(WIFI_STA);

Arduino Duemilanove woes

I've been attempting to use the gateway with an Arduino Duemilanove using a 433mhz RF transmitter/receiver, yet have been having quite a fair amount of difficulty in getting it to work. It seems that whenever I send an RF command, my RF transmitter will only send gibberish to the receiver. This transmitter/receiver pair has been working fine with my Raspberry Pi, so the transmitters do indeed work. The transmitter is connected to pin D4.

The console debug log: https://gist.github.com/IronWolfMC/c0afb79a549ab70cf66458b97755f1ae

RF Receiver output log (the code I sent was 5330227, instead the receiver is getting a single random digit): https://gist.github.com/IronWolfMC/271948abb980b2efcd95b47f6ce2437f

The Arduino is also receiving 'phantom IR transmissions' based on the console log, of which I cannot figure out what is going on. I do not have a receiver connected.

Thank you for any help.

OpenMQTTGateway.ini - user defined parameters not working

User defined parameters get trounced by the following two lines of code in OpenMQTTGateway.ino:

if (valuePLSL != 0) valuePRT = 1;
if (valuePRT != 0) valuePLSL = 350;

Everything works as expected if these two lines are removed and recompiled.

e.g. send MQTT command with RF Pulse Length: 180 and RF Protocol number: 1
mosquitto_pub -d -u user -P password -t home/commands/MQTTto433/PLSL_180/433_1 -m 5321996

Port fan example as an addon instead of a complete separate program

Openhab users warning

It took me three weeks to find the solution why the IR send function did not work in my Openhab2 configuration. The space character between "{mqtt=">[broker:" and "home/commands/IR_......" is essential.
No space char = not working...

Change the acknowledgment to be Home assistant compatible

see:
https://community.home-assistant.io/t/433mhz-infrared-ir-to-and-from-mqtt-on-esp8266/6779/141?u=1technophile

Limitation of sending IR value > 2147483647

When sending value > 2147483647 the data sent by IR is limited to 2147483647

Avoid duplicate of RF signals for multiple gateway installations

Goal is to removes duplicate signal received when several gateway are used, for instance if one sensor emit and the code is listened by two gateway they will previously send two code by MQTT. With this modification it should not be the case anymore.
The first gateway that listened the code send the code to the other gateways by MQTT, these gateways store the code into their ReceivedSignal array to check against this array when the code is received by RF.

Add RFM69 gateway

Hi, your work is AWSOME! But did you consider adding other RF transmitters?
Like for example nRF905 transceiver?
I could not find anything about connecting it to a Esp8266, but maybe you know more about this

Homie convention

Hi, first of all let me congratulate for such good project. I love it and I'm investing quite time on testing what you explain, so thanks a lot.

I just want to ask if you considered on following the [Homie convention](https://github.com/marvinroger/homie) on top of the MQTT layer? I used to use OpenHAB and now I'm migrating to Home Assistant and in all devices that I integrate using MQTT I follow that convention, I think it's very useful.

Regards and thanks your opinion about it.

Duplicate

Hey fantastic job on this but I was wondering if you could implement a simple change to remove duplicates. My sensors send duplicate codes to ensure that it is received. Can you implement duplicate removal code? I have changed the code to basically do this but only checks the last code that was sent. This fails if one of the codes sent is not read properly or if 2 sensors fire at the same time. I am using a toggle feature in home assistant so makes it difficult and i will sometimes get 2 toggles.

I used the time feature now() and imported.

Add OTA option for remote updating

It would be a nice option to add an OTA update option so that new updates can be sent via WiFi

Could you add support for AC's maybe, like Mitsubishi

geoisis:
Awesome project !!!
Although i can't get 433ghz receiver to snif anything, IR works fine.

thank you for work, keep it up :D !

Add RF and IR repeater function

The goal is when a signal is received tfrom RF or IR to repeat it with the emitter, taking into account loop issues (if multiple gateway don't loop the signal)

Change to GPL V3 license

As I have to use part of examples that are GPL V3 licensed I need to change the license. Moreover some libraries licensed GPL and not LGPL could be studied for integration like rfm69 from lowpowerlab

Adding DHT sensor

I have enabled the sensor in the User_config.h "#define ZsensorDHT" but I cannot see where the pins are enabled for the dht11 to be picked up from?

Add the ability to pass the RF protocol with the gateway

Merge arduino and esp8266 code

Docu: Needed/recommended Features of NodeMCU Firmware

As new nodemcu firmwares are only available via custom firmware builder (https://nodemcu-build.com/) it would be helpful to have a list of modules, which are needed in order to run this project (min requirements/recommended modules)

Add bluetooth sensor for presence detection

Add a publication of advanced receiption data to a topic

So as to analyse the rf signals it could be interesting to retrieve by mqtt the protocol type, the pulselength and other advanced parameters

Add static IP adress for esp8266

Cannot compile with error "avr/interrupt.h: No such file or directory"

Dear all,

I'm very new to this arduino environment and this is actually my first project to explore my smart home study. I have installed the Platformio software, imported the "OpenMQTTGateway" project folder and compiled the code. i quickly realised that i am also required to get all the related libraries and put into the lib folder to make use of the additional libraries.

i have got myselfe IRremote, IRremoteESP8266, pubsubclient, and rcswitch from the internet and put into the lib folder. my compiling process went further until i met the following situation which i cant proceed anymore:

`Compiling .pioenvs\nodemcuv2\lib\Ethernet\utility\w5100.o
Compiling .pioenvs\nodemcuv2\lib\rc-switch-master\RCSwitch.o
Compiling .pioenvs\nodemcuv2\lib\Arduino-IRremote-master\IRremote.o
lib\Arduino-IRremote-master\IRremote.cpp:21:27: fatal error: avr/interrupt.h: No such file or directory
#include <avr/interrupt.h>
^
compilation terminated.

*** [.pioenvs\nodemcuv2\lib\Arduino-IRremote-master\IRremote.o] Error 1
[ERROR] Took 17.75 seconds`

i realised this is a standard lib from the arduino suite and i went to install the arduino software, copied all the lib and put into Platformio global lib but i still cant get past this error.

Can anybody please help to enlighten me on this? thank you very much in advance.

Regards,
Kenny

esp8266 enable sendPanasonic and sendRCMM

You might want to include IR support for IR_PANASONIC and IR_RCMM. I managed both with a little update of your code.
Inside user_config.h after line 127 add

  #define IR_PANASONIC
  #define IR_RCMM

Inside ZgatewayIR.ino after line 240 add:

  #ifdef IR_PANASONIC
  if (strstr(topicOri, "IR_PANASONIC") != NULL){
    irsend.sendPanasonic(0x4004, data);
    signalSent = true;
  }
  #endif
  #ifdef IR_RCMM
  if (strstr(topicOri, "IR_RCMM") != NULL){
    if (valueBITS == 0) valueBITS = 32;
    irsend.sendRCMM(data, valueBITS);
    signalSent = true;
  }
  #endif

I also managed a "long power on" press for the Panasonic, however that needs some additional changes in IRremoteESP8266.h and IRremoteESP8266.cpp

Byron

Hi

I'm very new to this having been using the RFLink433 unit - someone pointed out this code - so - I put together an ESP8266 and the RF receiver... I am looking at the serial signal and with a little handset I have - the unit is picking it up no problem (other than reboots sometimes when setting up).

However it is totally ignoring my Byron SX35 doorbell pushes - should it know about these?

mqtt LWT Online / Offline fix

The announcement should be retained.
client.publish(will_Topic,Gateway_AnnouncementMsg,will_Retain);

This will fix online/offline weirdness to will Topic.

Integration of 315 Mhz RF

It would be nice to integrate RF-Receiver and RF-Tranmitter for 315 Mhz.
Using Modules für 315 Mhz with the actual settings for 433 Mhz does not work.
