Heatpump controller

@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/
-
It is usually printed in serial monitor at startup .
...or by calling gw.getNodeId();

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.

Nice Job!

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?
-
Answer in big blue box here:
http://www.mysensors.org/build/serial_api25 bytes.
-
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.
-
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.
-
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...
-
Wow, great job @ToniA
Would you consider creating a pull request with the example and HeatpumpIR library when you feel finished?
-
@hek, I created pull request #211. I think it's good enough, the challenges are really on the Domoticz side.
-
Thanks, I'll take a look!
-
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.
-
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.
-
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?
-
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.
-
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?
-
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...).
-
@johnr did you see that : instructables article and associated github
-
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
-
mharizanov's version of Daikin was different, the protocol now seems to have one extra frame which seems to carry the wall clock time.
The HeatpumpIR library now has the initial (untested) Daikin support.

Hello,
I'm trying to build a sensor node to control a Panasonic AirCon and I'm having trouble (using the latest MySensors and Heatpump-IR libs).
Whenever the node tries to send IR it restarts. I tried switching RF24's CE and CS pins in case the timers conflict and tried to reduce sram usage as much as I could to no avail.I'm using a nano and RF24 wireless modules. The hardware works ok with other sketches (for example a simple relay ON/OFF).
Here's the sketch:
#include <Arduino.h> #include <MySensor.h> #include <MyTransportNRF24.h> #include <SPI.h> #include <Timer.h> #include <avr/pgmspace.h> #include <PanasonicHeatpumpIR.h> #define ACW2_CHILD 2 // Id of the AC Warm 2 hours child #define ACW6_CHILD 3 // Id of the AC Warm 6 hours child MyTransportNRF24 radio(7, 8, RF24_PA_MAX); MySensor gw(radio); MyMessage acw2Msg(ACW2_CHILD, V_LIGHT); MyMessage acw6Msg(ACW6_CHILD, V_LIGHT); IRSender irsender(9); PanasonicNKEHeatpumpIR *ACIR; Timer t; boolean ac_state = false; void setup() { // Initialize library and add callback for incoming messages gw.begin(incomingMessage, AUTO, true); // Register all sensors to gw (they will be created as child devices) gw.present( ACW2_CHILD, S_LIGHT ); gw.present( ACW6_CHILD, S_LIGHT ); gw.sendSketchInfo("AC", "1"); } void loop() { // MySensors Process gw.process(); // Timer Process t.update(); } void incomingMessage(const MyMessage &message) { if (message.isAck()) { Serial.println(F("This is an ack from gateway")); } if (message.type == V_LIGHT) { boolean state = message.getBool(); if (message.sensor == ACW2_CHILD) { if(state){ Serial.println(F("--- received ACW2 - ON")); schedule_auto(6600000); //schedule_auto(6000); } else { Serial.println(F("--- received ACW2 - OFF")); ac_off(); } } if (message.sensor == ACW6_CHILD) { Serial.println(F("--- received ACW6")); if(state){ schedule_quiet(21000000); } else { ac_off(); } } } } void schedule_auto(int dur) { Serial.println(F("--- sending auto")); ACIR->send(irsender, POWER_ON, MODE_HEAT, FAN_AUTO, 26, VDIR_MIDDLE, HDIR_AUTO); t.after(dur,ac_off); ac_state = true; } void schedule_quiet(int dur) { Serial.println(F("--- sending quiet")); ACIR->send(irsender, POWER_ON, MODE_HEAT, FAN_1, 25, VDIR_MIDDLE, HDIR_AUTO); t.after(dur,ac_off); ac_state = true; } void ac_off() { Serial.println(F("--- trying off")); if (ac_state) { Serial.println(F("--- sending off")); ACIR->send(irsender, POWER_OFF, MODE_HEAT, FAN_1, 25, VDIR_MIDDLE, HDIR_AUTO); ac_state = false; gw.send(acw2Msg.set(false), true); gw.send(acw6Msg.set(false), true); } }Here's the Serial output:

Hi,
Great news !
I've tested the DaikinHeatpumpIR library and I can report that it works with my Daikin Heatpump, type RXS25G2V1B
FVXS25FV1B
the remote is ARC452A1I'm really happy that it works and would like to say thank you to the dev's !
Finally I will be able to start some real energy saving by controlling the Daikin heatpump based on conditions like presence, outside temp, (google)-calendar, and heath generated from a second central heating system (allowing me to choose most economic heathing source).I already have a Nano based sensor node (near the Daikin unit) for PIR motion detection and DHT22 temp/humidity, so hopefully I can manage to integrate the simple ON/OFF via IR into the same sketch.
If not, another dedicated node will be needed.
@ ToniA, do you expect problems when integrating this into the same Mysensors sketch as PIR + DHT22 ?Bye,
DirkB

@Panos-Toumpaniaris said:

Yes you are
You just have an uninitialized pointer to PanasonicNKEHeatpumpIR, while you should have this instead:
PanasonicNKEHeatpumpIR *ACIR = new PanasonicNKEHeatpumpIR();
-
@DirkB19 said:

It should be fine. Just make sure that if you have any interrupt handlers (PIR?), make sure they execute fast so that they don't mess up the timings. It's probably not a very good idea to disable interrupts while sending the IR, as the IR sending takes several hundreds of milliseconds.

Just got my Sensebenders this week. I can confirm that the HeatpumpIR library works also on the Sensebender
Nice...
-
@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?
-
I just got it running on Sensebender today, on my desk. The problem is that this is not a 'sensor', but an 'actuator'. So it needs to listen to the radio all the time. I believe it would not run on batteries for too long.
I was asking about how to power the Sensebender in another thread, but didn't yet get any real answers. So let's try once more:
What kind of schema should I use to power the Sensebender (with NRF24), provided that I have +5V DC available, and I have a bunch of different capacitors and 'LE33ACZ 5V-3.3V Step Down Regulators'?
-
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 Hi, do you have a guide on how to set up Domoticz with this example? I understand enough about mysensors and domoticz to be dangerous but i dont get how Domoticz can send the right command....
-
Take a look at this topic on the Domoticz forum: http://www.domoticz.com/forum/viewtopic.php?f=34&t=8751

@SGi
Hi,
I have created the wiki:
https://www.domoticz.com/wiki/AC_/_heatpumpIREverything is based in Toni's great effort
I also first used the mysensors Arduino, but since I am still using "old" mysensors ver 1.5.4 (And currently I don't have time to upgrade to latest and greatest, which support text based commands)
Then I have taken same approach as Toni and use Wemos D1 Mini Pro that uses HTTP or MQTT wifi
-
Thanks for the library it's great. I can also confirm that it works with Fujitsu remote AR-REB1E out of the box.
Trying to integrate this into HomeAssistant and just do not know where to start. Is there any example how to post a whole string of commands for the air cond via mysensors-MQTT?
-
So nobody is using it this with MQTT gateway?
-
@bjacobse if I have a new Daikin heat pump with a newer remote that is not in the library, I guess I'm out of luck, right?
-
@moskovskiy82
hi, I'm not using the MQTT with mysensors
I think you should direct your questions to a HomeAssistant forum.
My setup uses Wemos D1 Mini Pro and Domoticz
-
@gohan
Please use the github for heatpump to ask you question, as I assume that Toni mostly is checking that. It seems that there 2 different Daikin heatpumps supported
-
@bjacobse Can you elaborate a little more on how you wired things up?
Also how you combined the libs and compiled everything for easyESP?
Have a sonoff with easyESP and docs are not that clear how to that stuff
-
@moskovskiy82
I took 5v from the heatpump, mine is an IVT, I took it from the Ir receive, soldered 2wires, one GND and on for 5V and drilled a hole on the plastic casing, and then I had power for the Wemos D1 Mini Pro module.
Then 100 Ohm resister in series with the Irda LED 940nm Ir LED, connected to GPio16/D0 on the Wemos module.Downlaod the ESPEASYT files + download Tonis heatpump /P115 lib and put it in same Arduino IDE, compile it all together
-
I want to make heatpumpIR, but after trying to send the signal using simple.ino sketch to my Sharp A/C nothing happened. Confused where to start ....
-
@Ispandy
did you look at the previous comment?
to make it easy for you, then don't use mysensors with Arduino for this, it's too difficult to setup, but instead use the Wemos and ESPEASY using your WIFI
-
@bjacobse There is nothing difficult in setting it up. Just connect the irda to the 3rd PWM leg
-
@moskovskiy82
I certainly agree, I assume your comment actually was meant to Ispandy
