Heatpump/air conditioner as a Domoticz device

Post by Toni »

I've been playing around with heatpump/air conditioner control with MySensors (see http://forum.mysensors.org/topic/622/he ... controller and https://github.com/mysensors/Arduino/tr ... Controller). It's now technically possible to control many heatpumps/air conditioners with Domoticz, but it's quite clumsy as there's no support for this device type on Domoticz side. Right now I'm using a 'Text' sensor with an encoded hex string as the value, and a switch to trigger the 'Text' sensor value to be sent. And some custom Lua events...

Would it be possible to implement support for a heatpump/air conditioner device? I think it would be enough if a 'MySensors' sensor type 'S_IR' could be defined as a heatpump/air conditioner sensor. In the settings (behind 'Edit') there should be the possibility to define the model somehow (it could be a plain number, or a name of a heatpump/air conditioner device). The UI itself should have capability to set these properties
  • Power state (ON/OFF)
  • Temperature (integer)
  • Operating mode (auto, cool, heat, fan)
  • Fan speed
I have attached some quick mock-ups I made about the intended UI design (I made these by editing the HTML in browser 'developer' view). The 'Set' operation should change all properties at once, and then trigger the 'V_IR_SEND' type of message towards the sensor. The message could be encoded for example like I have done in https://github.com/mysensors/Arduino/bl ... /README.md.

Is there really no interest in this?

I just added a feature request on the tracker for support of the s_hvac sensor of my sensors.
It's up to the developers from here on..

Hi,

I'm dealing with the same issue. I'm considering to buy 4 of the Remotec zxt-120 to control 4 of my Mitsubishi Heavy air conditioners.

I did a little reverse engineering on the Mitshubioshi Heavy remote control IR codes (used AnalysIR).

The idea was to setup some Arduinos (in a ZBee network) with IR leds to control the air conditioners. This idea stopped because of time consumption.

Now I installed Domoticz with RFXOM and Z-wave USB stick to make a more generic solution.

So if I could eliminate the 4 Remotecs and develop a MySensors solution with IR leds, temperature, humidity, CO, etc. for each room with an air conditioner, it would be great.

Controlling my 4 air conditioners from Domoticz would be a nice christmas present :D

I am going to test the solution for Arduino with my Midea air-cons and if it works (and I suppose so), I would be very interested in full control via Domoticz.

Do you share some more details about Heatpump/air conditioner?

What do you want to know? The specific information about the Mitsubishi Heavy? Or how to control an air conditioner with Domoticz?

Toni added support for my AC into his great arduino-heatpump project. Using that project, and with his plugin for ESP EASY, I am able to control my AC in form:

$ curl http://192.168.1.7/control?cmd=heatpump ... 0,3,1,23,3

Where the last numbers are the control commands for AC (on/off, tempaerature, fan speed, AC mode).

What Toni said in the first post, it's still not available a device like this? Even a dummy device would be great, If we can make it work with ESP EASY&HEATPUMP plugin.

Bump for this. World is full of heatpumps and that's also one of the juiciest areas to do some home automation. Even there are plenty of different models the basic requirements/control needs are the same: temperature, mode, fan speed. Like RGB light/dimmer there should definitely be a heatpump option in Domoticz's device type list.

How did you put the ESP Easy together with the ESP EASY plugin? I have been searching around but not easy to get the complete picture is there a block diagram I have overlooked?

I'm using this version of ESPEasy on my projects: https://github.com/ToniA/ESPEasy, build it with PlatformIO (http://platformio.org/), as I needed to increase the MQTT message size buffer (Domoticz is VERY verbose). With Arduino IDE you need to manually modify the PubSubClient code...

In Domoticz I have a 'text' sensor on the dummy hardware. This sensor has a text value like 'panasonic_nke,1,6,5,10,0,0'. This value is calculated by the event scripts, and it's the value the ESPEasy looks for. In the event script I update the text value like this:

Code: Select all

commandArray[1] = {['OpenURL'] = 'http://127.0.0.1:8080/json.htm?type=command&param=udevice&idx=' .. otherdevices_idx[apartment .. ': ' .. textDev] .. '&svalue=' .. modeCmd}
Then I need to have an MQTT broker running, I'm using Mosquitto on the Domoticz host.

Finally, the ESPEasy firmware is configured to connect to the MQTT broker on the Domoticz host, and it has a device definition like this:
* Device: Heatpump IR transmitter
* IDX/Var: Domoticz IDX of the text sensor
* 1st GPIO: The pin the IR led is connected to (connect in series with a resistor, then connect between G and the GPIO pin of your choice). Remember that the IR transmission range is not that great without any amplifier, something like 1 meter will work fine

Now I got the Espeeasy + Toni's heatpumpir working, I can now control the heatpump with http/url commands.
Did anyone create a script that combines the modes, fan speed and temperature? or is the Daikin-wifi script handling this?

Hi Toni,

I'm also automate my airco and while building a proto, it didn't took me long before I came across your great piece of code.
Thank you very much, this helped me a lot as I needed a kickstart to use it with a esp8266 without PWM.
The Carrier codes look a lot like the Toshiba, but not fully.

I've decoded a Toshiba WH-H04JE remote for a split unit.
I like the challenge to continue and update your code.

What is the best way to reach you and share my data?
The forums I'm subscribed to, don't allow me to send private messages yet :)

Regards,
Gaston

Dear Toni,

What is the brand and type of you pump/airco?
How is your opinion/experience to this stuff?

Happy with it?

This works quite well, but you have to remember that this is one-way communication, so the A/C device does not give any feedback. I have support for quite a few different models, just see the readme of the library: https://github.com/ToniA/arduino-heatpumpir

I have for example built an automation project for a village of summer cottages, where the aim is to remotely control both the A/C heatpump devices and the electric radiators, so that the indoor temperature can be kept at ~8C - ~10C while the apartments are not rented, and then remotely switched up to normal heating when the apartment is rented.

You can for example PM me on this forum, or find my email address in Github...

I ended up creating a WIKI page:
https://www.domoticz.com/wiki/AC_/_heat ... heatpumpIR
Very nice. I do the almost same thing but with just only one PWM pin for test purpose and soon plan to handle my all house fans and heaters with it .
Here I am facing with

Code: Select all

print("String Print: = "..'http://' ..IP.. '/control?cmd=PWM,' .. PIN..','..CalcValue..'')
commandArray['OpenURL'] = 'http://' ..IP.. '/control?cmd=PWM,' .. PIN..','..CalcValue..''
and in this commandArray['OpenURL']=........ line after executing I found error in log like this
2017-11-23 03:00:36.181 Error: Error opening url: http://192.168.1.50/control?cmd=PWM,2,854

2017-11-23 03:01:06.193 Error: Error opening url: http://192.168.1.50/control?cmd=PWM,2,944
Any one have any clue for this and I think its look like its not properly executing CommandArray[]=... with variables
But on when I do fixed values with CommandArray[].... like this
commandArray['OpenURL'] = "http://192.168.2.50/control?cmd=PWM,2,1";
It did and I saw changing LED behavior on my LED and it work
