Thnx Ron! Just wasn’t sure.
[RELEASE] Remotec ZXT-120 AC IR Controller (2015)
In the new smartthings app I’m Getting a Can’t connect to device. Anything I can do to fix that? Or gotta wait till the new app is gonna support it?
Unfortunately I don’t know. SmartThings has done little to tell us how this will work going forward. I worry when they retire the classic very little will work anymore.
I have reported this to them. The only thermostat that I have that connects it a Z Wave Plus with security. Remotec ZST 500.
Is there a smartapp that would allow me to change modes (Off, Cool, Heat etc) changed by the presence or departure of a presence device like a phone or a SmartThings Arrival Sensor? I want to make sure the AC turns off when my wife leaves the house. Thank you, Dan
I have not used this one, check out
There is also thermostat mode director.
Thank you for the quick response! I’ll take a look at these!
Incorrect remote. Now that you have a correct procedure for configuration, go back and try other codes.
Not sure why you are replying to my post from over 1 year ago and I have no clue what you are suggesting. What was the point of this post?
What makes you think I am using the wrong remote code?
Sorry to have troubled you Ron. I was posting to another member and did not realize I had replied directly to you.
I do have a question for you, though. Have you found a way to get the temperature to update on the ZXT-120? It is very slow on my device and Poll and Refresh don’t make it update.
Also, I would like an app that turns it to Dry at one RH (using external sensor) and Off at another and only runs in Away mode. Have you seen such an app?
Third, can you suggest a way, or add, a button that turns the AC on and Off only, but keeps the last setting? The interface has a rotate through the modes operation, and not a switch.
Thanks for your work and attention.
No, the zxt-120 requires that you poll for temp and SmartThings Polling has always been broken. Not sure why they can’t fix it but they have tried and it has never worked correctly. So I use a Fibaro Motion Sensor for Temp reading because it posts updates as temps change.
What is an RH?
You must not be using my Device handler. Mine doesn’t cycle through the settings.
Do you have any clue why this doesn’t work with ActionTiles?
I saw on their support forum that device should be visible if it has some capabilities like Sensor, Actuator…
But I can’t see it in ActionTiles SmartApp where I add permissions to devices so I can’t add it to panel and I can’t even see it in ActionTiles UI.
I have had the zxt-120 working good for quite some time. Suddenly it completely disappeared from smartthings and all routines. As if it never existed. That was strange. I now reset the zxt120 fo factory settings and was trying to add it again to smartthings but was never able to. Smartthings never detects it … Any help or hints ? Has anything like that happened before ?
@Fab Try excluding it first. But first make sure you configure always listening mode. (explained in manual)
- put device in always listening mode
- make sure device is plugged in to usb (don’t use batteries since it doesn’t work with always listening mode)
- exclude the device first (put hub in exclusion mode and then wake the include/exclude mode on the zxt-120)
- try including, it should work now.
thx Ron!! It worked following the process !
Just 1 note: status is not updating. ie I turn the AC on, it turns on but it always gives me Off in the smartapp status. Other ZXT120’s that I have work perfectly using same device handler and they show status correctly.
on a related note Any idea why would the device just disappeared from smartthings ? Have anything like that happened before ?
Did you switch the DH to the correct version after including? It might have found another matching device handler and attached to that. If you are changing the status of the AC using the AC remote or the device itself it does NOT report back to the zxt-120. For status to be correct you must change the AC using ONLY the zxt-120 control. Because of this I don’t pay attention to the current state. I simply select the discreet state I want it to be in or I let automation handle it. If I turn the AC on using the AC remote I know it will not be correctly reflected in ST and that has never really bothered me. If you are trying to use state to take other actions this might be tricky. If the AC is a plug in unit I might put it in a smart switch so I can monitor power flow to determine current state, I do that with a heater I use the ZXT-120 for. If it is a split system determining state might be more tricky. You could but a tilt sensor on the vent and see if that lets you know if the vents are open (running) or closed (off). But I never tried that.
No I have never had that happen. If you didn’t have it in always listenting mode perhaps that was an issue but it shouldn’t disappear it should just not be responsive.
Thx Ron !
helpful as always. All working good now
I have had the zxt-120 working very good with one unit. But I would like to control another AC unit located om another room, using the extender IR Port from the zxt-120.
Any one knows if it is possible?
Only if they are the same unit and you want them to do the same thing all the time. Whatever signal you issue will go to all IR senders that are active. If they are different units it is not possible since only one programmed code is allow at a time.
I have 5 split AC units and a heater driven by zxt-120’s so I had to purchase 6 of them.
They are not the same model but are from the the same manufacture(the same ir controller).
For the moment I will try to use the external IR but I will do the same you did(one zxt for each unit).
