Heatpump controller

Fredrik Carlsson

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 <Arduino.h>
            #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);
              
              Serial.begin(9600); 
              delay(500);
            
              Serial.println(F("Starting"));
              Serial.print("Node Id is set to: ");
              Serial.println(gw.getNodeId());
            }
            
            
            void loop() 
            {
            
              gw.process();
             
            }
            
            
            
            void incomingMessage(const MyMessage &message) {
              // We only expect one type of message from controller. But we better check anyway.
              if (message.type==V_HEATER) {
                 int incomingHeatingStatus = message.getInt();
                 if (incomingHeatingStatus == 0) {

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?

Fredrik Carlsson

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

Hi,

Thank you for the inspiration. I skuld like to use this to control my Daikin heatpump in my cabin. Unfortunatley I am not able to travel there for I while to access the remote. I think I need it to analyze the signal since Daikin is not supported by the library you used.

I am thinking just two buttons (on 22 degrees/ on 10 degrees)

Did you stumble over any Daikin codes while working on this project?

Maybe it is possible to use the code these guys decoded http://www.hifi-remote.com/forums/viewtopic.php?t=11769

Fredrik Carlsson

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?

hek

Answer in big blue box here:
http://www.mysensors.org/build/serial_api

25 bytes.

@johnr

I'm taking my first steps with IR sender/receiver because I'm also looking for controlling my DAIKIN heatpump.
I assembled IR receiver, IR sender and nano and loaded From the examples IR Sender/Receiver sketch.
It works with the remote of my Samsung TV, which it recognises as NEC.
Daikin is not recognized.
My Panasonic TV remote is not recognized.
My Telenet Set-Top box remote is not recognized.
I guess there is a IRlib for Panasonic, right ?

Thx, guys !

Nice to see that my little HeatpumpIR library made it all the way here :)

I'm also quite new to MySensors, I actually just started today, I've had all the necessary hardware on my table for some weeks now... My goal is to power a (physically) small MySensors device directly from the Panasonic heatpump, and hide everything within the indoor unit's covers, and have it fully controlled by Domoticz. There's quite a bit of work to do, as for example Domoticz does not have a suitable devuce type yet.

And how about MySensors, I'm still quite a newbie on the messaging schema... Is there a schema which could be used to communicate all of these within the same message:

ON/OFF information (0 or 1)
Temperature information (integer from 8 to 30)
Fan speed information (integer from 0 to 5)
Mode information (COOL, HEAT etc. i.e. integer from 0 to 6)

What comes to Daikin, it would probably be quite easy to add it into the HeatpumpIR code, provided that I could borrow the remote controller for a while. Or, if somebody else could decode the protocol.

johnr

ToniA,

Where are you based? I maybe can send you my remote, if I am sure to get it back ;)
I think it will be a challenge to send all the information with only 25 bytes.

ToniA

In live in Finland...

I now have the HeatpumpIR working together with Domoticz, so that I can also define which commands to send from Domoticz. And yes, 24 bits is plenty enough :)

https://github.com/ToniA/arduino-heatpumpir/tree/master/examples/MySensorsNode

@johnr, do you happen to have an infrared receiver module? If you do, I could assist you in decoding the protocol. This is how I for example got the Mitsubishi protocol decoded, I've never had a Mitsubishi remote controller myself...

hek

Wow, great job @ToniA

Would you consider creating a pull request with the example and HeatpumpIR library when you feel finished?

ToniA

@hek, I created pull request #211. I think it's good enough, the challenges are really on the Domoticz side.

hek

Thanks, I'll take a look!

ToniA

I finally managed to get rid of all compiler warnings :) I must say I like your CI build system, I'm also running Jenkins at work, actually running the build system on Jenkins is my primary job at the moment...

So the heatpump IR sender node is now one of the examples on the MySensors 'development' branch.

hek

Thanks for the work you've put into the HeatpumpIR library,

All creds go to @Anticimex who did the setup of the headless Arduino IDE builder in Jenkins. Messy business to get it right ;)

But it is really nice to get intant compiler feedback on changes and pull requests for different platforms and boards.

johnr

ToniA, I can collect the Daikin remote from my cabin during next week. I have the following IR-reciever, is it enough to decode it per your instructions?

http://www.ebay.com/itm/380746925201?rmvSB=true

ToniA

Yes, I think it would work. I have used this piece of software to decode the bits from the remote.

If you have any heatpump/AC remotes at hand, you could try it out already now. It should also work with TV remotes etc. The only thing is that you might need to adjust the limits it's using to tell the one's and zero's apart.

johnr

Hi Toni,

inally I was able to fetch the Dakikin remote from my cabin. What type of software did you say you use to decode the remote?

ToniA

Quite a co-incidence, I just finished decoding the Sharp/IVT infrared protocol, and pushed my decoder changes into Github:

https://github.com/ToniA/Raw-IR-decoder-for-Arduino

This is the hardware you'd need, just about any Arduino would do, I'm using both Duemilanove and Mega: https://github.com/ToniA/Raw-IR-decoder-for-Arduino/blob/master/arduino_irreceiver.png

If you get the hex sequences and timings out, I can assist with the rest. We can discuss the detail over email (take a look at my Github profile...).

fets

@johnr did you see that : instructables article and associated github

ToniA

Interesting... I took a look at mharizanov's work, and I think I might have a decoder for the protocol here: https://github.com/ToniA/Raw-IR-decoder-for-Arduino

Would you try if this correctly decodes the protocol? I would also appreciate some full outputs of successful decode, together with the explanation of the state the remote control shows after the button press.

If the decoder is correct, creating a Daikin module for the HeatpumpIR library will be a piece of cake :)
