Heatpump controller
-
you could try to get a basic device like a relay or a thermometer and explore.
then, once you get through the steps, and you know what it takes to put it together, you will have an easier time of it.
catch your first bass before you go marlin fishing kind-of-thing.

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 commandsI revert with some kind off code later this weekend
All input and help is highly appreciated

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:1Have 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!!

How can i see which node id the sensor gets? -
@Fredrik-Carlsson said:
I am not sure which node id the controller gets
Which controller? Do you mean the node?
@Damme might be able to help with the MQTT stuff.
You should see a "starting" message. If not there might be a code problem.
loop() should at least contain gw.process() to pick up incoming messages.
-
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/ -
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 thatThanks for all the help, as I said I have almost no programming nor Arduino knowledge since before. Just starting out.

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) { heatpumpIR[0]->send(irSender, POWER_OFF, MODE_HEAT, FAN_AUTO, 22, VDIR_AUTO, HDIR_AUTO); delay(500); Serial.println("Setting mode to "); Serial.println(incomingHeatingStatus); } else if (incomingHeatingStatus == 1) { heatpumpIR[0]->send(irSender, POWER_ON, MODE_HEAT, FAN_AUTO, 21, VDIR_AUTO, HDIR_AUTO); delay(500); Serial.println("Setting mode to "); Serial.println(incomingHeatingStatus); } else if (incomingHeatingStatus == 2) { heatpumpIR[0]->send(irSender, POWER_ON, MODE_HEAT, FAN_AUTO, 22, VDIR_AUTO, HDIR_AUTO); delay(500); Serial.println("Setting mode to "); Serial.println(incomingHeatingStatus); } else if (incomingHeatingStatus == 3) { heatpumpIR[0]->send(irSender, POWER_ON, MODE_HEAT, FAN_AUTO, 23, VDIR_AUTO, HDIR_AUTO); delay(500); Serial.println("Setting mode to "); Serial.println(incomingHeatingStatus); } else if (incomingHeatingStatus == 4) { heatpumpIR[0]->send(irSender, POWER_ON, MODE_HEAT, FAN_AUTO, 24, VDIR_AUTO, HDIR_AUTO); delay(500); Serial.println("Setting mode to "); Serial.println(incomingHeatingStatus); } else if (incomingHeatingStatus == 5) { heatpumpIR[0]->send(irSender, POWER_ON, MODE_HEAT, FAN_AUTO, 25, VDIR_AUTO, HDIR_AUTO); delay(500); Serial.println("Setting mode to "); Serial.println(incomingHeatingStatus); } else if (incomingHeatingStatus == 6) { heatpumpIR[0]->send(irSender, POWER_ON, MODE_HEAT, FAN_AUTO, 22, VDIR_UP, HDIR_AUTO); delay(500); Serial.println("Setting mode to "); Serial.println(incomingHeatingStatus); } else if (incomingHeatingStatus == 7) { heatpumpIR[0]->send(irSender, POWER_ON, MODE_HEAT, FAN_1, 22, VDIR_UP, HDIR_AUTO); delay(500); Serial.println("Setting mode to "); Serial.println(incomingHeatingStatus); } else if (incomingHeatingStatus == 8) { heatpumpIR[0]->send(irSender, POWER_ON, MODE_HEAT, FAN_3, 22, VDIR_UP, HDIR_AUTO); delay(500); Serial.println("Setting mode to "); Serial.println(incomingHeatingStatus); } else if (incomingHeatingStatus == 9) { heatpumpIR[0]->send(irSender, POWER_ON, MODE_HEAT, FAN_4, 22, VDIR_UP, HDIR_AUTO); delay(500); Serial.println("Setting mode to "); Serial.println(incomingHeatingStatus); } else if (incomingHeatingStatus == 10) { heatpumpIR[0]->send(irSender, POWER_ON, MODE_COOL, FAN_AUTO, 18, VDIR_UP, HDIR_AUTO); delay(500); Serial.println("Setting mode to "); Serial.println(incomingHeatingStatus); } else if (incomingHeatingStatus == 11) { heatpumpIR[0]->send(irSender, POWER_ON, MODE_COOL, FAN_AUTO, 20, VDIR_UP, HDIR_AUTO); delay(500); Serial.println("Setting mode to "); Serial.println(incomingHeatingStatus); } else if (incomingHeatingStatus == 12) { heatpumpIR[0]->send(irSender, POWER_ON, MODE_COOL, FAN_AUTO, 22, VDIR_UP, HDIR_AUTO); delay(500); Serial.println("Setting mode to "); Serial.println(incomingHeatingStatus); } } }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?

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

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?

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.
-
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...
