I will try tomorrow to do it without any voltage regulators together with a sensebender micro. I have the bigger pir sensor though, but I dont think its much difference on thoose. We will see.

@m26872 Hello, have you not used any voltage regultator for the pir sensor? You just give it direct connection to the batterypack?

Hello
It would be nice to make it run on batteries, maybe with 10 seconds sleep, and then wake up only to check with gateway if there is a new command and then sleep again.

I am building a pir sensor now based on 3*aa batteris running on 4,5 volt.I will ust use an LE33 step down directly after the battery pack to provide power to both sensebender+radio+pir. Dont know if that is the optimal way to do it but it should work

@ToniA
Hey, thanks for all the work you have put down. I have had some other projects going the last year so have not really put down more time on this.

How is it working with the sensebender? Are you using it on batteries?
Any ide about battery usage?

Wonderful!
Maybe I will try this design then. But I dont need them so small so will probably use the bigger PIR sensor in mine.
I will revert when I'm done

Hello
I am busy building an burglar alarm for my home.
Because of this its important its a wireless system (to not go down during electrical failure in the house).

I wonder is there any stable good PIR sensor that works with battery?
I have sourced the forum but not really found anything. I have a couple of Sensebender micro boads lying around that I would prefer to use for this.

Its off course also important that there is no false triggers, because then it would be a very unreliable system.

@AWI

Yes i am. but there is mistake in the picture the R3 is connected between Pin 3 and VCC, not ground (pull up resistor).

Then that leaves me hanging a bit because that is way more than I will be comfortable with in terms off battery changes.
Any suggestion what to do?

Hello again.
I just got some new 470k resistors today so i changed out the 10k/4,7k resistors on the battery circuit to 1mohm/470k
The current draw is now 0,63mA when sleeping and 17,6mA when sending.
Especially the sleeping current seem very high. Any ideas to why?

hmm think i solved the problem. I tried with an arduino uno instead and now the sketch works fine. Very strange

Hello
I have installed a 3 phase meter for my waterheater.
It is on 3 kw and is also equipped with a ledpulse.
I have made a sensor and flashed it with the standard sketch. I have only changed the pulse/whr to 800 as that is what my meter says.

But I get this very strange watt values. I get in the serial log printed watt: around 42000
the meter says 2994 +- which is also correct because its a 3000 w heater.
I did a manual test and clocked 20 pulses looking at the meter and divided by 20.

then i got 1,465 ms which calculates to around 3090 watt so the optical out on the sensor is working good. I have also tried putting a 10k resistor between ground and D3 pin without success.

The arduino is a arduino nano clone bought on ebay. I have also tried with another one but with same problem (arduino nano clone also). Could it be that the timing is corrupt on theese clones? Or do you have any other suggestions?

Yes I tried now again an now it works. Maybe something temporary with Dropbox yesterday

@tekka Hey, it seems like the downloadlink is broken. Can you check?

@AWI Hello, yes I was aware of that. So it could be possible that configuration no 2 is working, just that it is not possible to measure. .. I will try when I come home. And yes the led is detached. I will also change resistors for the measurement circuit. Just need to order some 470k resistors

Aha, that could probably be the cause then
I have now tried with the following 2 scenarios:
Using internal pullup, then i get the current draw 2,85 mA in sleep, which is quite high?

I tried to deactivate the internal pullup and used a 1Mohm resistor as external pullup instead but then the sketch doesnt even start.
As referenced to this thread: http://forum.mysensors.org/topic/1287/door-window-sensor-consuming-more-power-when-closed/3

**Or is the cause the fact that I am using 10k/4,7k resistors for battery measurment instead of 1m/470K ? **

So this one is working

And this one is not working

Hello
A somewhat stupid question
I have a arduino 3,3 volt without step up or anything. Driven by 2 1,5V batteries.
All positive lines (DHT22 +battery + battery measuring circuit) is connected on Vin pin and all ground cables on ground pin. So fairly simple circuit. Isnt it just to put in the multimeter somewhere in the circuit? Then i read around 4-5mA but the arduino restarts all the time, dont really know why?

How to correctly read current on an arduino circuit?

@funky81
Hello. I have had a hard time testing this. Is the future for the pulsesensor implemented in 0.8.17 official plugin?

If not, how get the latest commit in to pimatic? Have tried to git clone the plugin and then npm install inside the folder, but then none of the sensors shows up in pimatic (the plugin is not active)

With official 0.8.17 the arduino sketch just come in to an endless loop where it wants the latest pulsecount = no answer from pimatic

Hello
haven't had the opportunity to test yet.
will try to find time tomorrow

Yes saw it on github, very interesting. Will try as soon as I am home again

@Dheeraj I wait patiently then
Yes the more im digging in to pimatic the more i like it and feel that it fits my needs perfectly

Good morning @Dheeraj
Do you have any example for how you are configuring it? I have made a node with the "original" sketch and configured it with sensor array [0,1,2] in pimatic. I see the device, with parameters w/kw/kWh but no info comes in. Are you using a custom sketch then or how is your setup working?
I think one of the nicest things about pimatic is the graphing functionality. I want to log and and check how the heating is distributed throughout my house and at which consumption depending on heatpump / woodstove settings

Hello @Dheeraj
Any info about how to setup a pulsecount sensor?

@Mike-Cayouette thanks, I will try that tomorrow!

@vikasjee I am still working on my own system. Started to learn MongoDb and AngularJS so i am building my own frontend based on node-red as backend.

There is another guy at the node-red maillist that has made a simple "mobile-app" based on node-red with a pure javascript/jquery setup. Check it out here: https://github.com/industrialinternet/Node-red-flows-mobile-web-app

Well.,
I have tried now for one hour to reproduce the problem without success. I have now a laptop running where the gateway is but have to take this down soon. I will try again another time

Yes it's the mqtt gateway. I will try tonight with a to take a debug log. I just have to find a long enough ethernet cable

Hello
I have experienced with both Node-RED and OpenHAB that when i restart this controllers the gateway stalls and i must manually reset it.
It is not every time it happens though.
I have tried to search the forum without success. Has anyone else experienced this?

@mbj said:

V_VAR2

Nice trick!
I did that also and now everything seems to work!

I am currently working with node-RED.
Here a simple setup storing the pulsecount in a global variable (but is off course reset after reboot of the node-RED so store this in a database of choice)

Hello
First I tried to use the sketch from MySensors, but it was a little bit to advanced for what i needed and also it didnt work to good with mqtt gateway (requested for variable 1 and got no answer).

Anyhow I tried to make this more simple version which only sends current consumption (have not started on kwh yet, first want to get this working).

I try this scetch and it boot up, but then it completly stalls after sending first kwh message. I get 1 V_WATT message, but nothing in the serial monitor.
Any ideas?? I am very uncertain about the variable declarations, maybe I have done something strange there?

    #include <SPI.h>
    #include <MySensor.h>  
    
    #define CHILD_ID 1              // Id of the sensor child
    
    MySensor gw;
    
    long pulseCount = 0;   //Number of pulses, used to measure energy.
    unsigned long pulseTime,lastTime; //Used to measure power.
    unsigned long watt, elapsedkWh; //power and energy
    int ppwh = 1; //1000 pulses/kwh = 1 pulse per wh //Number of pulses per wh - found or set on the meter.
    
    MyMessage wattMsg(CHILD_ID,V_WATT);
    MyMessage kwhMsg(CHILD_ID,V_KWH);
    
    void setup()
    {
    
      gw.begin();
      Serial.begin(115200);
      
      // Send the sketch version information to the gateway and Controller
      gw.sendSketchInfo("Energy Meter", "1.0");
    
      // Register this device as power sensor
      gw.present(CHILD_ID, S_POWER);
    
    // KWH interrupt attached to IRQ 1  = pin3
      attachInterrupt(1, onPulse, RISING);
    }
    
    
    void loop()     
    { 
    }
      
    void onPulse()
    {
    
    //used to measure time between pulses.
      lastTime = pulseTime;
      pulseTime = micros();
    
    //pulseCounter
      pulseCount++;
    
    //Calculate power
      watt = (3600000000.0 / (pulseTime - lastTime))/ppwh;
      
      //Find kwh elapsed
      elapsedkWh = (1.0*pulseCount/(ppwh*1000)); //multiply by 1000 to pulses per wh to kwh convert wh to kwh
    
    //Print the values.
      Serial.print(watt);
      Serial.print(" ");
      Serial.println(elapsedkWh);
      
     //Send mqtt message 
      gw.send(wattMsg.set(watt));
      //gw.send(kwhMsg.set(elapsedkWh));
    }

ok so here is a example.
please note, i am not a programmer so the code might not be the slickest, but it does its job.
What this on is doing is basically emulating 3 mqtt inputs, whit options to see 2 different temperatures.
Send it over via websocket and also use a http request node to serve a webpage straight from nodered, styled and everything, but without use for a server. Pretty nifty
So now i must just create 3 temperature sensors and add them instead of the input nodes.

Some pictures:
Node-RED:

And the webpage generated at localhost:1880/temp:

Here is the code for the nodes:

Hello
I have been tinkering a little with this and it does actually work.
The only thing is that you must point the topic of the mqtt node directly to a child. Its not possible to just subscribe to topics higher in the hierarchy.

For example in MyMQTT app on Android i can just subscribe to topic MyMQTT and then i get messages from all nodes connected to the Gateway. This is not possible with the mqtt node in NodeRED. You must specifically point it.
below is and example of an mqtt node outputting to a debug node. My Gateway is at 192.168.1.201.

[{"id":"d0ff7866.2f0088","type":"mqtt-broker","broker":"192.168.1.201","port":"1883","clientid":"MQTT"},{"id":"14e0544d.eb1fac","type":"debug","name":"","active":true,"console":"false","complete":"false","x":304,"y":827,"z":"cda8f31c.32571","wires":[]},{"id":"8792e08c.786d2","type":"mqtt in","name":"Temperatur","topic":"MyMQTT/21/1/V_TEMP","broker":"d0ff7866.2f0088","x":67.5,"y":791,"z":"cda8f31c.32571","wires":[["14e0544d.eb1fac"]]}]

I am working on some code to push temperatures as an object trough a websocket for live viewing on a simple webpage.
It maybe sounds advanced, but it is actually very easy. In my opinion Node-RED is just as powerfull as OpenHAB and not particulary more advanced either. Will post a full working example when i have everything ready.

Hello
nice that you cna use it for something
Sorry, I have no idea regarding Daikin, but if you build sometihng to record the codes with maybe you can figure it out and just add that to the library somehow?

Anyway, i have thought more about this and i do actually want to be able to make it a little smarter than the code above.
It would be nice if its possible to send a whole string direct from the controller. ie "send(irSender, POWER_ON, MODE_HEAT, FAN_AUTO, 21, VDIR_AUTO, HDIR_AUTO)" Then I can on the controller side make all the logic and that way have complete control of how the heatpump behaves.

I have tried to search a little, but can not find any concrete answer. How big is the maximum size of the payload you can send with this library?

Well, after a few restarts of both the node, the gateway and openhab it suddenly works.

well, i have run into some problems. It doesnt have anything to do with the sketch though. Its either OpenHab or the gateway that is causing headache.

First of all, I have changed the code into this:

            // Example sketch showing how to control ir Heatpumps
            // An IR LED must be connected to Arduino PWM pin 3.

            #include <PanasonicHeatpumpIR.h>
            #include <MySensor.h>
            #include <SPI.h>
            
            
            
            #define CHILD_1  1  // childId
            
            IRSender irSender(3); // pin where ir diode is sitting
            
            MySensor gw;
            MyMessage msg(CHILD_1, V_VAR1);
            
            HeatpumpIR *heatpumpIR[] = {new PanasonicJKEHeatpumpIR(), NULL};
              // will take away everything except PanasonicJKE when everything ready to reduce sketch size
            
            void setup()  
            {  
            
              gw.begin(incomingMessage); // Start listening
            
              // Send the sketch version information to the gateway and Controller
              gw.sendSketchInfo("IR Sensor", "1.0");
            
              // Register a sensors to gw. Use binary light for test purposes.
              gw.present(CHILD_1, S_HEATER);

With the Android app MyMQTT I have tried the different modes and all works, Currently the scetch has been up running a couple of days without problems.

The problem is when i try to do this from OpenHAB.
First of all, the Mqtt binding IS working, at least with inbound messages because I have also a couple of temperature sensors and that works fine. But when i try with the following setup the command line of openhab shows: "Heatpump received command ON", but nothing is happening with the arduino. Very strange. Any ideas?

Openhab Item:

       Switch Heatpump (varmesystem,All)      {mqtt=">[mysensor:MyMQTT/20/1/V_HEATER:command:ON:1],>      [mysensor:MyMQTT/20/1/V_HEATER:command:OFF:0]"}

OpenHAB Sitemap:

     Switch item=Heatpump label="Värmepump"

Any ideas what is going wrong?

TOUCHDOWN!
Here is working code. Whit this i can with mymqtt android app publish topic MyMQTT/20/1/V_LIGHT with message "1" for heatpump on (with 24 degrees etc etc) and "0" for heatpump off. I have tried it with my Panasonic heatpump and it works.
I also added a little serial string in order to find out node Id (mine was 20 then)

Next step is to increase the different modes.
I was thinking from beginning of only having 5 different "hardcoded" modes that would actually be more then enough for my use, but it would be really nice to send over variables some how instead so you have complete control of the heatpump from OpenHAB (temp, heatingmode etc). I am just not sure about how long messages you can send with the nrf protocol. Must dig into that

Thanks for all the help, as I said I have almost no programming nor Arduino knowledge since before. Just starting out.

Haha yes i have forgotten gw process in the loop. that is corrected now.
Yes i want to know which mqtt address the node has (for example i have 2 temperatures nodes with id MyMQTT/20/ and MyMQTT/21/

@Fredrik-Carlsson no ideas?
How can i see which node id the sensor gets?

Hello
I have made the following code (actually not, made i have combined the heatpump example sketch and the ir mysensor sketch to make a controller that can turn ON/OFF the heatpump. But... It doesnt work. I am not sure which node id the controller gets **(how to check that??) **

How is the MQTT message structured?
I have tried to send the following with an android app (who is connected to the gateway off course)
Topic: MyMQTT/22/1/V_LIGHT
Message:1

Have also tried node id 23-28 without result.

I have a couple of temperature nodes working with MQTT and Openhab so the "system" is working for sure.
But its easier to just find a published message. Harder to publish i maybe??
Any ideas/suggestions?

One thing I have noticed is that I dont get the "Starting" message in the serial monitor.
Is maybe something happening which stalls the code before that?

All help I can get is highly appreciated!!
ps, the code inside the do loops is already tested and confirmed working in a simpler sketch without mysensors library.

              // Example sketch showing how to control ir devices

Hello
You are of course right
I have successfully made a couple of temperature sensors and more or less also got a humid understanding about how the code works.
What I hesitate about now is how to go further.
I think the easiest is to evaluate the incoming message in a switch statement from where I send 5 different commands

I revert with some kind off code later this weekend

All input and help is highly appreciated

Hello

First of all, I know very little about programming and Arduino but I am trying to learn.

I just dont get the whole picture about how to use this library in the right way for this project.

I want a microcontroller for controlling my heatpump via OpenHAB. I have sucessfully tried this library with the simple example provided in the library and it works https://github.com/ToniA/arduino-heatpumpir

What I want to do is to make a sketch that is based on a arduino + the nrf24 and the mysensors library.
If you look in the sample sketch for the heatpump library https://github.com/ToniA/arduino-heatpumpir/blob/master/examples/simple/simple.ino it should be quite simple to adapt this.

I dont have the need to send variables over the nrf24 i can hardcode maybe 4-5 different states the heatpump library sends and then just control them with different values (ie value 1 = heatpumpIR[i]->send(irSender, POWER_ON, MODE_HEAT, FAN_2, 24, VDIR_UP, HDIR_AUTO);, value 2 is maybe power off or something

Does anyone have a clue about how to customize this to a mysensor?
Which sensot item etc should i use?

Any help and input in this matter will be higly appreciated
