I'm getting following error while compiling, any solution?

@FotoFieber I followed the sketch that you provided in your link above called "MQTT Client Gateway". however, while compiling that sketch I'm getting following error?
Any solution or suggestion for that?

@FotoFieber I'm using THIS MQTT Gateway. Is there a better MQTT gateway solution available? Sorry i'm new to all this.

@gadu How did you implement V_Var1 ? and assign it to child ID 1 ?

Like this? if so, what did you use for gw.present(CHILD_ID, S_XXX) ?

#define CHILD_ID 1
myMessage msg(CHILD_ID, V_VAR1);

Thanks alot @gadu . I will give this a try and get back to you!

@gadu Can you post your working battery level send sketch for openhab? I would really appreciate it. I'm facing the same issue. Thanks!

Hello

I'm trying to receive battery percentage over MQTT on openHab. So far i'm dont have any luck. I'm confused, because there is no such V_Battery or something like that.

I would really appreciate any help as i'm trying to finish my project before my final exam starts.

Here is my serial output. I was testing the battery sketch on Nano powerd via USB 5.0v. I know i'm getting incorrect reading, but thats okay for now, I just need to receive battery percentage via MQTT first.

@andriej you can toggle internal led on pin 13

@Striffster I surly will.

@hek Thats right, I only get one way communication. Domoticz doesn't send cmd via Ethernet for some reason.

@hek You mean this isn't an issue with the ethernet gateway but Domoticz itself? I will open a support ticket with domoticz. Thanks!

@Tango2 Here is a tutorial for that. Hope that helps

Do you have an air conditioning duct? What about using a temperature sensor?

I second that. I have exactly the same issue. I have to physically toggle the switch before operating it from OpenHab.

Hello,

I wanted to report my or some other members issues with Ethernet Gw and Domoticz. It seems that Ethernet gateway only works one way and not other with Domoticz.
I was able to get status updates on Domoticz via Ethernet gateway but I couldn't send any command to any nodes.
Ex. I could see all the sensor data, relay's physical button status update but I could not send a on/off command to the relay. There's just no response from Ethernet Gw if issues a command from Domoticz UI.

I tested serial gateway, it worked without any issue.

Thanks!

@mikeones I apologize to get back to you so late. You might already have figured out a way but I wanted to let you know that after many days of testing my relay actuator with OpenHab, I'm very happy to tell you that it's working flawless. No issues with the stuffing inside the gand box whatsoever. I have not seen any other option to power the arduino thru 110V - 240V. Using a cellphone charger seems to be common.

Please let me know if you have any other solution, I would certainly give it a try.

Thanks!

Edit : gang box

@andriej this is off topic but I wanted to ask you if are able to turn off/on relay actuator thru domoticz UI via Ethernet gateway?

It's not working with mine!

@Striffster Before this, I was running OpenHab via MQTT gateway. It works flawless.
I wanted to give Domoticz a try but the ethernet gateway wont work.

@blacey Are you running Serial or Ethernet gateway for Domoticz?

For my light switch i'm using the example relay actuator sketch. When I try to turn on/off light from Domoticz UI via ethernet gateway it wont work. However, it does update state On/Off light if I toggle the physical push button on the relay.
On the contrary, everything works fine on Serial gateway. I just tried it and it worked.

Any solution please? I really want to use ethernet gateway!

Thanks!

@raditv @hek I can confirm that the Light turns on/off with Serial gateway. Just tried it and it works. However it does not work with ethernet gateway sketch. Any solution to make it work with ethernet?

@hawk_2050 I had few crashing issues today when I installed from source code. It ran fine for a while, got me excited and then started crashing. So I went ahead and installed from stable binary. So far no issues except I can not turn on/off light from the UI. Not sure if its the ethernet gateway issue or domoticz'.

@raditv Yeah, let me know if you face any issues with ethernet gateway. I will give a try to serial gateway, right now!

@raditv I used the default sketch given in examples for Relay actuator on mysensors. I checked my ethernet gateways debug log, it seems that its not receiving any command from Domoticz at all.

@jeylites After success with OpenHab, I wanted to give a try to Domoticz. Lets see how it goes. I will keep you updated!

@raditv @AWI Thats what I thought about On/Off action. I'm trying to on/off mysensors relay actuator. My relay actuator has a physical button. Domoticz detects my relay actuator and also updates the state if I toggle the physical button. But it does not turn on / off the relay actuator from domoticz UI. Any idea why?

Here is my Domoticz log

@blacey Thanks!! I followed your instruction. Works great. It detected some of my sensor noted out of the box. However, I'm not sure how to send a command to Turn On/Off light? It is asking me Action ON and Action OFF like shown here:

Do i need to install Domoticz beta version to get official mysensors support? Does anyone have a tutorial to setup ethernet gateway with domoticz?

Thanks!

I have achieved it using MQTT with OpenHab. So if some one toggles the physical button on the relay switch, the soft switch on OpenHAB will toggle to match the state.

Not sure if that's what you are looking for.

This is my very first fully functional project! Yay!! Most of the credit goes to mysensors and all the amazing people here. I thank you all.
So, I wanted to control my home appliances/lights with Voice and/or OpenHab rules. I made this relay switch outlet. May not look pretty at all but it surely works with OpenHab and "Ok Google - Turn On Switch" command from my Android phone and Android watch . It also hides behinds the couch, hehe. For right now, I just turns on/off and with commands. I will be setting it up to fully automate with iftt conditions in next few days.

Note: I have used 2 relay module because thats the one I had for now. Also I'm planning to make both female power outlets to operate separately.

Project cost: $7.5 USD including Nano V3.0, Relay, NRF transmitter, power outlet socket, and casing. (Power cable, button, 5.0V charger, AutoVoice, Auto-wear and Tasker not included, I already had them.)

I searched for cheapest required item on eBay and purchased hem.

Nano V3.0 = $2.56
NRF transmitter = $0.97
Relay module (You may use 1 relay module) = $1.3
Female powerOutlet socket + blue casing + faceplate = aprx. $3 from Home Depot.
PowerCable = n/a (used old PC power supply cable.)
Button = n/a (Already had it.)
5.0V charger = n/a (Already had it, just use old phone charger)
Tasker = n/a (Already had it.)
AutoVoice = n/a (Already had it.)
AutoWear = n/a (Already had it.)

My OpenHab & Tasker

Hope you liked my project. Please feel free to comment, post any suggests, and questions.

Thanks!

@andriej I'm using OpenHab and I was wondering about domoticz. Many people seem to be using it. Have you used OpenHab? Do you like domoticz better?

@andriej This is awesome! Thank you very much. Im going to try this.

@raditv I use mbp too. I boot camped Windows 8 in it. It runs great.

You can also use Xcode as Arduino IDE.

@andriej is there any link or tutorial on this? I'm fairly new so it would really help.

If I understand right, I can connect a transistor that you mentioned to rpi gpio and reset pin on arduino to achieve a rest when gateway is frozen? I'm correct?

I use Visual Studio with Arduino IDE plug in, Visual Micro. It's pretty good. It has intellisense and code completion.

@raditv Thanks alot. I will look into it and get back with results.

I have been facing this issue for quit a while. Every time I turn power off and on my mqtt gateway, it freezes. I have to reset the arduino uno to fix it. I'm using 1.4b version, arduino uno and w5100 ethernet shield if that helps.

I will appreciate your help with this issue. It's really annoying to rest it every time I reboot the gateway.

Thanks.

@raditv can you please elaborate on using eeprom to store button value? Any example link may be? Thanks!

I have been trying to control a two relay module using MQTT and openhab. So far I was able to control them individually. I can turn on relay one or turn off relay two and so on but I want to implement a single button which would control both also, in-case I want to turn on a light/device physically. Example: 1 press will trun on relay1, second press will turn on relay2 and third press will turn all relays off. or something like this.

I'm not very good at programming and still learning. Below is my code:
Note: my relay module is weird. Its Off on 1 (the led turns Off) and ON on 0 (LED turn On).

I would really appreciate any help you can give me. Thank You

@andriej I have not encountered any issues and its working perfectly for past 2 days. Also i'm still looking into resetting Arduino via GPIO.. Please feel free to share recommends or any ideas. Meanwhile, I will be adding an external arduino reset switch on my ArduPi Gateway .

@gadu Thanks!

Have you tried it with a different radio? It is possible that this radio may have been partially damaged when you powered it with 5v?

I look forward for the result.

Finished Product !

I decided to put my RPi and MQTT gateway in one box so made this. First time doing this, so it isnt that perfect. I will soon be adding LEDs to it too.

@TimO Thanks, I will try this.

@Chaotic Thanks! I will try this and get back with result.

How can I implement MQTT for MQ-2 Gas sensor the correct way? In the mysensor sketch there is only one child ID and one V_VAR1 but 3 different outputs: LPG, CO and Smoke? I'm only receiving CO value and not all 3 in openhab.

@kolaf If you could find, that would be very helpful. Thanks!

@rvendrame That is definitely a plus point. For me the question is, if serial gateway works with RPi + OpenHab?

@kolaf Great, Thanks for the response. The serial gateway sound a good option to me. I'm using RPi2 with OpenHab. Would you happen to have any tutorial link where I can look learn the to connect serial gateway to RPi with Openhab? Do I still need MQTT with serial gateway?

PS: I'm new to all this and do not hesitate to ask questions. Hope thats okay.

Thanks

I'm using OpenHab. So not sure about Vera. But I have the same issue. After using the code you provided, The node constantly sends messages 1 (Motion) or 0 (No motion). So I conclude, as Hek mentioned, the node can not sleep because it is waiting for incoming messages, I guess.

I'm currently running OpenHab on RPi2. I was looking at some other controller option just out of curiosity. Some of them support Serial and/or Ethernet gateway.

I'm wondering for ex. I want to try out Domoticz. It supports Serial and Ethernet. So, which one should I choose? Does it matter? Serial is better choice over ethernet or vice-versa?

would be great if you can shed some light on this. Thanks!

Got it. Thank you for your response. So I simply removed the sleep function and put if - else statement to stop my Motion sensor flooding my console window.

I'm attempting to merge Relay & Motion Sensor sketches, and so far i'm partially succeeded. But..

Here is the code that works for me: Relay and Motion both work.

// This example will remember relay state even after power failure.

  // Read digital motion value
  boolean tripped = digitalRead(MOTION_PIN) == HIGH; 
        
  Serial.println(tripped);
  gw.send(msgMO.set(tripped?"1":"0"));  // Send tripped value to gw 
  
  // Sleep until interrupt comes in on motion sensor. Send update every two minute. 
 // gw.sleep(INTERRUPT,CHANGE, SLEEP_TIME);
  
  
}

void incomingMessage(const MyMessage &message) {
  // We only expect one type of message from controller. But we better check anyway.
  if (message.type==V_LIGHT) {
     // Change relay state

     Serial.print(message.sensor);
     Serial.print(", New status: ");
     Serial.println(message.getBool());
   } 
}

However, My problem is that Motion Sensor continuously sends the message and does not sleep like the following log shows: I want the motion sensor to only send message when triggered.

If I uncomment the following line in the sketch, The Motion sensor sends message only when triggered (Perfect, thats what I want) but the Relay does not operate:

gw.sleep(INTERRUPT,CHANGE, SLEEP_TIME);

I would really appreciate any help with this issue.

Thank You

How to Turn On/Off a LED light on Arduino using OpenHAB and MQTT?

I'm fairly new to this and can not seem to understand how to send a command from MQTT to Arduino and make it to Turn ON and OFF a LED.

I'm able to read sensor data on OpenHab via MQTT. Following is my .items file:

Number	Node01Temperature	"Temperature [%.1f F]"	<temperature>	(GF_Living)		{ mqtt="<[mymosquitto:home/temperature:state:default]" }

Number	Node01Humidity	"Humidity [%.1f %%]"	<bath>	(GF_Living)		{ mqtt="<[mymosquitto:home/humidity:state:default]" }

Number	Node01Light	"Light [%d %%]"	<sun>	(GF_Living)		{ mqtt="<[mymosquitto:home/light:state:default]" }

Number	Node01Motion	"Motion [MAP(motion.map):%s]"	<shield>	(GF_Living)		{ mqtt="<[mymosquitto:home/motion:state:default]" }

Number	Node01Door	"Door [MAP(door.map):%s]"	<lock>	{ mqtt="<[mymosquitto:home/door:state:default]" }

Switch	Node01LED	"LED [%s]"	<switch> (GF_Living)	{ mqtt=“>[mymosquitto:home/led:command:ON:1],>[mymosquitto:home/led:command:OFF:0”]

The problem is, I'm not able to figure out how to receive this On / Off command on an Arduino sensor node?

Here is my Arduino sensor node sketch: I'm using RF24 library from Tmrh20.

  bool d = (digitalRead(switchPin) == HIGH);
  
  // Read motion: HIGH means motion is detected
  bool m = (digitalRead(pirPin) == HIGH);

  // Only send values if any of them are different enough from the last time we sent:

This is how my Openhab looks like

Please ignore temperature reading, It should be in Celsius. I will fix it later.

I really need help to implement the OpenHab On/OFF Led switch --> to MQTT mosquito --> Arduino.

I would really appreciate your help.

Thank You.
