Smart things and daikin split system

it definetly sounds intresting, given that i have 4 heads, buying 4 zxt-120 could be an expensive enterprise. I wish there was something like this but cheaper or extendable.

Please do link me on how to integrate the photon
i might get one of the zxt to see how it integrates, I definetly would like to get the feedback from the units if possible

There’s another company out there that makes something similar as well as the one you linked. I remember checking it out. Ultimately though it’s really just the same as using a photon and ir solution but a whole lot prettier and more expensive. I’m currently traveling but will find that links when I get home tonight or tomorrow.

thank you very much! appreciate your help!

Anyone try connecting a standard thermostat and using a mini-split adapter from this site?

http://www.minisplitcontroladapters.com

It would be great to be able to use a standard thermostat. But $150 seems pricey - esp as they don’t look like they’re UL listed or anything. I don’t see any other options (for connecting a standard wired thermostat).

There’s also the Daiken ENVi - which I think is an Ecobee with some kind of adapter module. These are over $300. But I’d love to hear people’s experience with this as well.

Ok~sorry I took so long. Here is some example code to work from. First is a very simple device handler for your photon. Basically it just sends the commands you want to the photon which then runs it’s code. The example simply has on and off but you could easily expand it to do much more.

/**

preferences {
input(“deviceId”, “text”, title: “Device ID”)
input(“token”, “text”, title: “Access Token”)
}

// for the UI
metadata {
// Automatically generated. Make future change here.
definition (name: “Spark Core”, author: "juano23@gmail.com") {
capability “Switch”
}

// tile definitions

tiles {
standardTile(“switch”, “device.switch”, width: 2, height: 2, canChangeIcon: true) {
state “on”, label: ‘${name}’, action: “switch.off”, icon: “st.switches.switch.on”, backgroundColor: "#79b821"
state “off”, label: ‘${name}’, action: “switch.on”, icon: “st.switches.switch.off”, backgroundColor: “#ffffff
}
main "switch"
details “switch”
}
}

def parse(String description) {
log.error "This device does not support incoming events"
return null
}

def on() {
httpPost(
uri: “https://api.spark.io/v1/devices/${deviceId}/on”,
body: [access_token: token, command: on],
) {response -> log.debug (response.data)}
}

def off() {
sendEvent(name: “switch”, value: “off”)
httpPost(
uri: “https://api.spark.io/v1/devices/${deviceId}/off”,
body: [access_token: token, command: off],
) {response -> log.debug (response.data)}

}

private put(led) {
//Spark Core API Call
httpPost(
uri: “https://api.spark.io/v1/devices/${deviceId}/led”,
body: [access_token: token, command: led],
) {response -> log.debug (response.data)}
sendEvent(name: “switch”, value: “on”)
}

Then in the photon IDE I had the following code that actually sent the IR commands to the AC unit. The hardest part of this was learning the IR commands. Ideally you can find them online somewhere but if not you will need to learn them from the remote control which is a bit of a pain.

// This #include statement was automatically added by the Spark IDE.
#include “IRremote.h”

int on(String args);
int off(String args);

IRsend irsend(D3); // hardwired to pin 3; use a transistor to drive the IR LED for maximal range

// Use the raw code you recorded from your device, in this example the length of the code is 37

I’ve also been looking for a good solution for my daikin split, and recently came across a few products… I haven’t tried any of them, but figured I would post some links:

Flair forum post:

Also, (…and probably MORE USEFUL / Expensive) It appears that the Diakin Envi thermostat is a re-branded Ecobee EMS, which has an open API. At some point I’m sure some smart person will figure out how to make the Ecobee ST app work with the Envi thermostat…

Thank you very much !, I didnt get a chance to get the parts yet, will update the thread once i make some progress

The Daikin ENVI which is an ecobee si integrated seamlessly. The unit is way overpriced tho.

I’ve stumbled here because I have a handful of Daikin units and I want them integrated with my ST platform. I’ve managed to install Internet-capable (wifi) controllers that allow me to use the free Daikin Comfort Control and Out-Of-Home system to run these things. Unfortunately I cannot figure out how to integrate this with ST - all roads lead to the IFTTT channel and, unfortunately, that seems to be broken and I’ve been trying for months to get a hold of IFTTT and Daikin for support, but neither reply in any way.

This unit https://www.acwholesalers.com/brd1274/BRP072A43-Wireless-WiFi-Interface-Adapter-For-Ductless-Systems/82541.ac works ok. The Daikin UI is absolutely terrible buuuuuut “technically it works.”

Any help figuring out how to get Daikin to talk with ST, preferably without a cloud-middleman like IFTTT, would be awesome!

I ended up buying their thermostat which is made by Ecobee so it integrates but it was like $400!!!

Paybax, Do you have a link to the thermostat that works with the ecobee?

No I had to get it through an installer and it was like $400 LOL. Its called Daikin ENVi and the only smart thermostat that’s compatible. The Ecobee App doesn’t work for it but the web interface does. Happy with it 1 Year later but removed the integration from ST. Does everything we need with it’s built in scheduling.

Hi Everyone, I created a device handler for the optional Daikin “WiFi Module” (e.g the BRP072A42) that is compatible with a lot of their Split System units.

Have a look here:

Hi folks

I am not new to smartthings but I am new to this device handler. I followed the instructions but when i look at the thermostat device in the phone app it has “items” displayed but they are all grayed out. I looked in the events log and didn’t see any listed.

I am hoping that I missed something simple or stupid on my part.

Help please

Is this thread dead ? hmmmm if it is no one will tell me that it is dead lol

Bump…

@polarbear @all4dom

Check out this thread. Works great for integrating Daikin split systems.

Thanks for the suggestion MRobi however unlike many people I have read through the entire thread and nothing suggests a fix for the problem I am having.

If you’re using the device handler that I linked to and having issues, you should probably post in that thread so the guy who wrote it will see it and be able to help. Reviving one from 2016 likely won’t get you many results since this thread has been dead for years.

Thank You MRobi, my stupidity thinking that was this thread.
