Daikin Heatpumps
OpenHAB controlled heatpumps
Highlights
- Powered by Daikin
- Direct injection to Daikin IR Receiver (no IR blaster)
- Direct feedback
- OpenHAB controlled to activate for heat when below 11 degrees and room has been marked as in use.
- Opposite will occur when I code for the opposite in summer time here.
- Heat pump remote can still be used and OpenHAB syncs to its state
WARNING: This build works around high voltage and directly injects into your heat pump.
My Company and I accept no liability whatsoever for your own well being or that of your heat pump.
Controlling the heat pump
In this modification, the Daikin heat pump is controlled directly from the Arduino. No IR Transmitter or blaster is used. It’s more technical, less portable, but more truly integrates and establishes the device as internet ready.
The basis of the code comes from the Arduino\Examples\HeatpumpIR\MySensorsNode example which in turn is based heavily on Ken Shirriff’s IRRemote library.
However, because we’re injecting directly into the IR Receiver and not using a transmitter, there are two small minor adjustments required.
- As the Arduino output connects directly to the Daikin’s IR receiver output pin, it only needs to transmit the coded signal, not the PWM carrier signal.Within the IRSender.cpp code, identify the setFrequency method. Set the output pin to High, then exit the method so the carrier is not established e.g.
void IRSender::setFrequency(int frequency)
{
uint8_t pwmval8 = F_CPU / 2000 / (frequency);
uint16_t pwmval16 = F_CPU / 2000 / (frequency);
pinMode(_pin, OUTPUT);
// digitalWrite(_pin, LOW); // When not sending PWM, we want it low
digitalWrite(_pin, HIGH); // Comment out the LOW above and set this to high
return; //Then return out of here so PWM is not activated<br>
switch (_pin)
{…
- To allow the standard IR remote, we must set the Arduino pin back to Input, so it doesn’t interfere with normal operations. In the main MySenors code after the heatpump instruction is send to this
heatpumpIR[model]->send(irSender, power, mode, fan, temp, VDIR_UP, HDIR_AUTO);
pinMode(3, INPUT); //When not sending IR signals, PIN 3 must be in INPUT mode so that the true Daikin remote control can send its IR signal.
Powering the MySensors Node
The node is running on 5V sourced from the Daikin unit’s IR Receiver. Ground is also from this. There’s a couple of pictures on this page describing and showing this connection and describing the pin out. As per further info below, don’t short this else you’ll be pulling the header units board out to replace fuse.
Regarding load on this voltage source and the mentioned fuse, I never had any issues with it, but to reduce potential & ensure no red light shines through the unit, I removed the Pro mini’s power LED (simply carefully crushed and pulled it off with my wire cutters). As I write this now though, I can’t recall if I did the same on the 3.3v regulator for the radio. That has a bright LED too. On one of the earlier builds, I simply covered that with a bit of paint 🙂
Obtaining the heat pump status
The heat pump status is obtained by connecting the heat pump status LED to the Arduino and a simple MySensors binary switch. However, the Daikin status LED has ~16v across it which is too high for the Arduino for a direct wiring. I used a EL4N35 Optocoupler in parallel with the LED to isolate the circuits.
In addition, to stop the Daikin status LED from dimming, a 330ohm resister was places in series with the optocopler.
Again, please be extremely careful with this build & I accept no liability whatsoever for any issues you may have with either your heat pump or your own life. You are dealing with high voltage components on one end and high cost components at the other.
I was extremely careful right through the prototyping stage to not cross the 5v wires from the heat pump. Unfortunately on the final wiring, they crossed and killed the Daikin board. After researching worst case alternatives & second hand ~$100 USD units from China, I set out to try and fix my board.
Two more nodes
Regarding this video: This is absolutely not a normal thing to to. The board is open and on the kitchen bench because I had to replace the fuse.
It’s connected to 240v and as I turn it on, you see the on-board LED begin to flash. As the camera then shows the laptop screen, after several seconds, the MySensors node which is connected to the board, the establishes communication with the MySensors Gateway and MQTT.
The re-occuring 1s and 0s represents the flashing status LED back within the black plastic. It will be doing this because it’s not happy that it’s not installed properly. In normal operation, the status LED is represented properly as either 1 or 0, On or Off back in OpenHAB.
I really don’t recommend you do this sort of thing yourself. This video is only for interested people and is not a how to guide. You run the risk of either killing yourself or your electronics. I don’t want to hear about either!
OpenHAB & Climate Control
We have a heat pump outlet in each bedroom. Each heat pump has 3 OpenHAB settings. Off, On & Auto. The first two are self explanatory and when using the standard Daikin remote, OpenHAB is synced automatically to the Off/On setting.
When OpenHAB has the heat pump set to Auto, this is when the fun begins. No longer do we control the heat pump, but instead we say that we are “Staying in the room”. This way, the house controls weather to turn on the heat pump or not. When the temperature outside goes below 11 degrees, the heat pump is turned on (and to Heat). When it rises above 12, it turns off again. There’s a 1 degree difference to stop is oscillating around 11 degrees while the night is still cooling.
I’ll configure the opposite controls when it gets to summer time here in New Zealand.
OpenHAB reports the current state of the heat pump.
The OpenHAB rules seem like a lot and they possibly are. However, I spent quite a lot of time getting them stable and to this point. I’m not to worried if there’s an extra line or two of logic in there. Certainly the tracing came in handy!
One day I’ll replace the manual “Staying in the room” selection with some smart presence detection. I’ll also be adding a rule that says around 9am in the morning, that regardless of the temperature outside, this switch will be set to false – basically, you should be out of bed!
