[RELEASE] Remotec ZXT-120 AC IR Controller (2015)

samster86 · September 23, 2017, 2:08am

I know I can have the app more then once. Is there a way you can add a
option for what time of the day to set the mode? Let’s say after 6am set
temp to 68( turn on heater when below 67 and turn off when over 69) then at
after 10pm set the temp lower to 55 (turn on heater when below 54 and off
when over 56).
Thanks.

Ron · September 23, 2017, 2:27am

Ah I see, not sure if that can be done. I suspect it could but difficult for me to test given temp is always the same in Hawaii. I could try to code and let you test if I can find some time to add that.

samster86 · September 23, 2017, 3:26am

That would be great. There is no hurry. Have a great weekend. Thanks.

Is there a way to turn off the display on the unit? I have a “light” button on the actual remote but have not found a way to turn it off via the app. If I turn it off w/ the remote, any command sent from ST will turn it back on, its also stuck on C too. Just change it in the DTH for F I assume. Any ideas about the display light?

My AC also has a “turbo” mode for the fan speed (low, med, high, turbo). I was unable to use the remote to pair with the remotec so I had to find the code and manually input a code that works. It’s a Gree mini split if anyone is curious.

Hi sorry for my newbie question
I just buy the smarthings hub v2
and also today I receive the zxt 120 from ebay
can you tell me step by step how to add it on my app or a link that shows the steps?

I have connect the hub to smartthings app
I have also copy the code and save and publish on api smartthings site for the device handler
and I have do the same for the app that start via change on temp

now how I can add the zxt to the app?

thanks and sorry

Edit I found and pair the zxt
Now I try all the code at remote code at settings and does not working so I try 1 by 1 all the codes from 1 to 550 is any other way? The learning code is exist?

@b16b This thread you just posted in and the Readme file should help you with step by step. It is a tricky device to set up so read carefully and do your homework.

github.com

gouldner/SmartThingsPublic/blob/master/devicetypes/gouldner/zxt-120-ir-sender-improved.src/readme.md

# Ron's Guide to installing the ZXT-120 device.

You can find a copy of the manual for this device here also in my github repo.  Note: This may not be your device's version so keep that in mind.  I find this version of the manual describes certain things quite well.  For example how to place the device into "Always Listening Mode.  Older versions of the manual that may come with your device have some errors in describing the steps.

[ZXT-120 Manual v1.0](https://github.com/gouldner/SmartThingsPublic/blob/master/devicetypes/gouldner/docs/zxt-120/rm-zxt-Zipato-Ir-Extender-User-Manual-v1.0.pdf)

## Install Custom Device Code
First you must install the device code into your ide.  For instructions on how to do this see the very helpful FAQ on the community site.
[How to install Custom Device Code](https://community.smartthings.com/t/faq-an-overview-of-using-custom-code-in-smartthings/16772)
If you are too lazy to read this FAQ you will miss out on some excellent features for linking github to your ide for easy updates in the future etc.  But I understand if you only want to do this once for this device it is a lot to digest so here is the quick and dirty steps.
1. Get the raw code copy of the device code and copy into your copy/paste buffer.  [RAW COPY](https://raw.githubusercontent.com/gouldner/SmartThingsPublic/master/devicetypes/gouldner/zxt-120-ir-sender-improved.src/zxt-120-ir-sender-improved.groovy)
2. Open the ide and switch to the [device tab](https://graph.api.smartthings.com/ide/devices).
3. Select "+Create New Device Handler" button.
4. Switch to "From Code".  Paste code you copied from the Raw Code Page.
5. Press "Create" to save this code and create your copy of the custom device code.
6. You should now see a device handler in your device handler list with the label "gouldner : ZXT-120 IR Sender Improved" assuming you made no changes to the namespace or name of the device handler.

## Join ZXT-120 to SmartThings
1. Make sure your deviced in connected to a USB charger.  It works best this way.  Battery mode doesn't respond as needed so I recommend connecting the device to a wired charger at all times.  The next step requires a battery.  Continuous listening mode doesn't work with batteries according to the manual.
2. Make sure the device is in Continuous Listening Mode.  To do this follow the instructions in the [manual] (https://github.com/gouldner/SmartThingsPublic/blob/master/devicetypes/gouldner/docs/zxt-120/rm-zxt-Zipato-Ir-Extender-User-Manual-v1.0.pdf) on page 13/14.

This file has been truncated. show original

Like any other app, select the configuration and select the zxt-120 you added.

Read the manuals that came with the device, it includes a list of IR codes.

b16b · October 11, 2017, 7:56pm

Thanks Ron I fix it the slider on smart app is different than your pdf and also not working for me

Is a way to make something like

If tempreture is lower than 18 open to heat and this only after 18:00

If is more than 24 open to cool only after 18.00 etc?

Ron · October 11, 2017, 8:37pm

Yea, Smart Things Changed the slider design. I hate the new version but nothing you can do. I don’t have time to fix the readme every time they make changs

Just saying doesn’t work for you doesn’t really help me understand what you need and as I said you need to do some homework to understand how this all works, your reply is so soon after mine I suspect you didn’t try very hard to solve any issue you have.

There are lots of ways to do this. You need to look at the smart apps, routines, modes. Basically you need to learn how to use SmartThings. My Smart App will handle the turn on based on temp and you can use modes to deal with the time. Another option would be to use something like CORE.

b16b · October 12, 2017, 11:21am

Thanks again for your great work and quick reply I will try to find how can make my scenario better…

For tempreture up and down I see only this new slider in black background and the only exit is by X first is not in Celsius and second whatever position I will left it nothing change

FYI, In the past 3 years, I have built the ScheduleTstatZones & ecobeeSetZoneWithSchedule smartapps which allow you to create zones inside your home for more targeted heating/cooling.

Here is the new virtual zone UI:

I’ve recently modified ScheduleTstatZones & ecobeeSetZoneWithSchedule to be able to control more effectively any portable coolers/heaters, split/window units based on My HvacUnit or the Remotec ZXT120 AC DTHs. For example, the smartapps can determine the best fan speed based on the max temp differential allowed for the zone(s).

For more details on My Flair HvacUnit, refer to:

*** No longer supported *** [RELEASE] FLAIR DEVICES with new capabilities for building physical zones in your home and controlling your mini/window splits, portable heaters/coolers Community Created Device Types

Hi, A contribution fee is required due to the amount of work for the design, development, and testing of the devices (equivalent of a few cups of coffee). The installation steps have been updated to reflect the fact that the installation can now proceed under the new SmartThings mobile app. To download the SmartThings code, go to www.ecomatiqhomes.com/store I’m happy to announce 4 more new devices under ST for better comfort and energy savings in your home automation scenarios.

In the ScheduleTstatZones smartapp, you can configure your rooms/zones/schedules. You then associate your zone/room thermostats to your zones and schedule your zones during the day.

In your home, you don’t always want to heat/cool all your rooms. In the evenings or at night for instance, you may want to direct more heat to your bedrooms.

The smartapp lets you choose a master thermostat which controls other slave (zone/room) thermostats in terms of mode and setpoints. The thermostats need to follow the ST standard capabilities.

You can also define enter some delta temp adjustments to make some specific zoned rooms cooler or hotter. You can also use your room’s motion sensor to take into account if the room is occupied or not. The occupied threshold can be defined on a room by room basis for more flexibility.

There are many other features, refer to the ST community wiki for more details:

http://thingsthataresmart.wiki/index.php?title=ScheduleTstatZones

And the following ST community thread:

*** No longer supported *** [OBSOLETE] Introducing ScheduleTstatZones: multi zoned heating/cooling solution for your home Community Created SmartApps

Hello there, ** UPDATE ** My smartapp is now officially approved by Keen Home: [image] This is the ultimate flexible smartapp for anyone who wants to better control her/his thermostat(s), and creates heating/cooling zones using Smart Vents like Econet, Keen Home vents or Ecovents. With this smartapp, you can also create “virtual zones” (without any vents) where you can then adjust the thermostat’s heating/cooling setpoints based on the avg temp calculated from different room sensors with the ‘occupied’ option or not. Actually, it should be the only smartapp that controls your thermostat(s) at home!!

Can anyone tell me what lines I must change to covert Fahrenheit slides to Celsius?

EDIT
I find solution
change this line

controlTile(“coolSliderControl”, “device.coolingSetpoint”, “slider”, height: 1, width: 2, inactiveLabel: false, range:"(18…28)") {
state “setCoolingSetpoint”, action:“thermostat.setCoolingSetpoint”, backgroundColor: “#1e9cbb”

18…28 was 67…84

do the same for the heat

Ron · November 16, 2017, 7:24pm

Glad you figure it out. There are comments in the code that tell you which lines to change. Your change will work but I already defined two sets of tiles you just need to switch between them.

The DH is commented to explain this.

github.com

gouldner/SmartThingsPublic/blob/master/devicetypes/gouldner/zxt-120-ir-sender-improved.src/zxt-120-ir-sender-improved.groovy#L321-L325


// change "coolSliderControl" to "coolSliderControlC" for Celsius
"cool", "coolSliderControl", "reportedCoolingSetpoint", 
//"heatingSetpoint", 
// change "heatSliderControl" to "heatSliderControlC" for Celsius
"heat", "heatSliderControl", "reportedHeatingSetpoint",

Also keep in mind the code looks at your Smart Things setting for C or F so if you mix them it will not work correctly. Only change to Celsius sliders if your ST setting is set to Celsius.

b16b · November 17, 2017, 12:52pm

Hi Ron thanks for reply as you see I found the solution but I have something new to ask
As you see with new update of SmartThings app have scenes I found the ZXT-120 but have only option for on and off and goes only at cool when you enable it even if your last time was heat can you add more option than on off… Also I use your smart app based on temp but again you can’t set to open at heat or open at cool

Ron · November 17, 2017, 8:08pm

@b16b

The open method is hard coded to call “cool” you can change that hard code to heat if you want. There is no way to know what your last setting was on the AC unit because it doesn’t report both ways. The ZXT-120 talks to the AC unit but the unit doesn’t report back. So if you turn on AC with the DH and then turn on heat with your remote it wouldn’t know your last setting. I could have coded it to remember the last selected mode but I had no need for that so I didn’t write it that way.

You can just change on to call switchModeHeat() instead of switchModeCool(). If you want both then you need a smart app that works with thermostat not just switch.

github.com

gouldner/SmartThingsPublic/blob/master/devicetypes/gouldner/zxt-120-ir-sender-improved.src/zxt-120-ir-sender-improved.groovy#L997,L1002




def dry() {
switchModeDry()
}


def off() {
log.debug "${device.name} received off request"
switchModeOff()
}


def on() {
log.debug "${device.name} received on request"
// Added "Switch Attribute on/off for Harmony Remote
// TODO: RRG add preference for on turns on heat or AC hard code to ac for now
switchModeCool()
}


// switchModeCommands
def switchModeOff() {
setThermostatMode("off")
}

I am not sure why you say my Smart App doesn’t let you select heat or cool. It definitely does.

Has anyone else struggled to get the device to learn? I was able to add it and pressing the yellow button causes the red LED to flash once. Yet when I try to get it to learn I only get the six flashes. The remote works (it’s a window unit and I plan on dealing with the various challenges there but i can’t start until I get it to learn anything)

b16b · November 19, 2017, 7:08pm

I want to learn also how can set the learn mode because my air condition have a button that cold powerful and goes to maximum for some minutes… And I want to have that

Hitchin999 · November 23, 2017, 4:43am

I’m trying this unit with power allowance but it doesn’t seem to turn off the unit after the 2 minutes (2 minutes was put for testing only) I guess he doesn’t take heat or cool as an on command?

b16b · November 30, 2017, 8:11am

I want this:
Example: if open A/C with ST from my phone from example at heat and 22C and then closed
If set routine to open A/C when I am back to home
Then open A/C at last settings in our example heat 22C

So the last settings of device handler is that possible?

A.Gennari · December 7, 2017, 1:39pm

Hello:
I’m a new user of Smarthing.
I got no ST programming skills.
I have installed several A/C units in my apartment.
Some are from LG and some from Samsung.
I got the code list from Remotec.
I’m buying their ZXT-120 AC IR controller.
Could any of you share a simplified step-by-step set of instructions to configure the devices from A to Z?
Thank you very much in advance.
Best.
Antonio

b16b · December 17, 2017, 2:57pm

I want to ask if somehow can connect 2x zxt-120 as 1 because i have 2 air condition in my living room…???

A.gennari you must
copy the code of git hub (tap raw)
then go to api smarthings web page log in
go to location select home then
click to device handler then
add new device handler
from code
paste the code
save
and publish for me
go to the app
tap + things
when searching push the button on top of zxt-120
you will found it then open the zxt UI
go to settings
put your code and save
the go at the buttom and push config and refresh

now everythings must work or just use one of the other codes for your aircondition
