@RBoy I’ve been trying to use a version of this to also include the ability to set the fan mode to auto, on, or circulate, but I 'm not a coder and I’m having a little trouble. Would you mind please referencing the thread below and tell me if you see something obvious?

Try this:

section("To this Fan setting") {
	input "fanSetpoint", "enum", title: "Which setting?", multiple:false, 

The change I made is double quotes.

RB, Thanks to you and other who helped!

Added option to select multiple days of the week now

Hi guys just new in Smartthings and bought a CT100 thermostat in addition of from my smartthings kit. I install your Ultimate Customizable tstat smartapps but heating still use the setting in the Thermostat itself and not with this smartapps. I can change mode(heat/cool/auto/off), fan(auto/on), temp adjustment from smartphone app And have no clue about it. Even use the Make me Cozzy II prior. Still the same thngs happen. Need some help regarding with this maybe theres a problem like this before but i just don’t find in the forum. Thanks.

but heating still use the setting in the Thermostat itself and not with this smartapps

Explain some more what you mean by that. You’re setting a temperature through the smart app but the set temperature on the physical thermostat does not match what you’re setting in the app?
What about if you change the temp from the device on the ST type app - does that reflect on the physical thermostat?

I mean the furnace still runs according to the setpoint of the thermostat (ct100). It doesn’t response according to the smartapps setting. Heating setpoint in CT100 was 70 and I try to put heating set point in the smartapps at 72. And the furnace still will stop at 70 not at 72. Yes when I change temp setpoint in STapp it reflects to the physical thermostat

Like I scheduled for all week at 11am putting heating setpoint at 72 on the Individual thermostat smartapps. So at that time setpoint on heating should also change to 72 instead of the previous setpoint of 70 but it doesn’t.

So what you’re saying is that when you change the temp in the STApp through the device user interface (under things) the change shows up in the thermostat (say 72) but the thermostat still cuts off at 70.

If that’s the case then you likely have a defective thermostat or your thermostat swing is set too high. To change the swing, click on Menu on the physical thermostat, there will be a on the top center will the swing number, click to change it and reduce it to 0.5 or 1.0

Swing is at 1 already. I don’t know if I explain it properly to you. Physical thermostat right now setting is at 70 heating and 75 cooling. Now I configure the Ultimate Customizable thermostat (Also called Individual Change Thermostat) in Four instances the same “all week” but the time is at 7am, 11am, 6pm, 9pm with 70deg, 72deg, 69deg, 67deg. on heating setpoint respectively. With 75deg cooling for all 4 instances. So is the physical thermostat setpoint will change to 72 deg at 11pm, 69 deg at 6pm, 67deg at 9pm automatically or not? Because when I look at the activity on thermostat in STapp thing it still cuts off (heating stops) at 70 deg. Means heating did not respond to the 4 instances setting I mean 3 because one instances is already 70deg.

Okay I understand what you’re saying but I’m trying to isolate whether the issue is with the app/thermostat communication or thermostat issue internally.

So when you look at the thermostat, it will have 2 numbers, in center (BIG and bold current temp), and the target temp at the bottom left corner.

At 11am it should change the target temp to 72deg (according to your post). Can you verify what target temp shows at 11:01am and 11:05am (sometimes the timer may fire slightly later)?

It was still 70deg. But by the way I think problem was solved. On that evening I notice that there is update for smartthings app Updated it. At 9pm in front of the physical thermostat am watching the setpoint change from 70deg to 68 deg. I’ m glad that it works already. Maybe theres a problem in smartthings app in android that the smartapps doesn’t communicate to the STapp thing. And thank Rboy for sharing thoughts trying to resolve my problem.

One question Rboy could i use two smartapps for the thermostat? Because I want a setting for away. The ultimate customize thermostat there’s an option for the mode so I will just exclude the away on that option. Is there any smartapps that trigger the thermostat base on mode? Anyway i will just search in the forum.

Yes that’s a pretty common way to use it. When you setup the app options scroll down to the last option which says Only during Mode and select everything except Away. Then you can use another app (or your can edit your mode and select change thermostat temp) for away mode similarly.

Thanks I got it.I can still use the same smartapps. Oh one more thing do i still need to set the time or leave it blank so it will trigger anytime as long its on away mode.

Not sure what you meant by this. The way ST works is that apps are never constantly running, they are run at events or schedules. So if the app is configured to work while in away mode, then the schedules/event will make the app execute it’s functions. If it isn’t configured to work in away mode then those functions will never be called even if the schedules/events are hit while in away mode.

So say if you’ve set the app NOT to operate in Away mode and you configure it to change the temp at 8:00pm. Say at 8:00pm the hub in away mode, this app will NOT be called so the temp won’t change. Say at 8:15pm you change the mode back to Home, since the schedule has passed it will NOT call the app. This is by design since this Ultimate App is designed to set the temp at a particular time it cannot guess when the next temp change is set (another instance of the app), it could be 1 minute or 1 hour or never, so the app doesn’t second guess the user’s intention here.

However if you use the 5-2 Thermostat I’ve published below, that DOES know that there are only X number of schedules set by the user in a day, so if the app returns from Away mode back to Home mode (e.g. as before it’s configured not to work in away mode), the app will determine that the last trigger didn’t fire and will set the temp to the appropriate temp within the current scheduled time. So say for e.g. you set the return temp to 70 and time to 7:30pm and the sleep temp to 65 and time to 11:00pm, as in the above case since you’re in away mode at 7:30pm it won’t change the temp, but when you change back to Home mode at 8:15pm, it will detect that the schedule didn’t fire and the next temp change is scheduled for 11:00pm, it will change the temp to 70 at 8:15pm (which it the temp set between 7:30pm and 11:00pm). Hope this helps.

On user request, created a new app to turn the Fan on/off on a Schedule:

Fix for changes in ST platform


I was just looking at this and wondered what thermostat’s this was compatible with? I have a Nest and have yet to find a good SmartApp/DeviceType combo that takes advantage of many of the features of my Nest. I didn’t see Nest anywhere in this thread and the picture seem to indicate it was for some other z-wave type of thermostat.
