[RELEASE] Vivint CT200 Thermostat Driver

JasonJoel · July 26, 2020, 6:03pm

Vivint CT200 Thermostat Driver
Hubitat driver for Vivint CT200 Z-Wave Plus Thermostat.

Features:

All standard thermostat functions
Exposes device specific functions such as:
- Manual fan timer command
- Temperature and humidity reporting thresholds
- Temperature sensor calibration command (and preference)
- Swing temperature setting (# of degrees from setpoint before HVAC turns ON)
- Energy Saving Mode - relaxes setpoint 4 degrees (so basically an 'away' mode)
Supports Hubitat Google Home integration

To-Do:

Consider adding in the Eco Mode Mode Types
Consider adding power type report (C-Wire or Battery) as an attribute

Untested:

Did not test heat pump functionality, as I don't have that equipment.
Alexa integration - I don't use Alexa.

Installation:

Install Driver code in Hubitat
Apply to a Vivint CT200 device. Click save.
Edit preferences, save preferences.
Click Configure command button

Driver can be imported from:
https://raw.githubusercontent.com/Botched1/Hubitat/master/Drivers/Vivint%20CT-200/vivint_ct200.groovy

v1.1 Posted. If you don't use currentSesnorCal, no need to update.

Version 1.1 - 07/26/2020 Fixed currentSensorCal not recording correctly

adamkempenich · July 27, 2020, 2:07pm

It's not.

adamkempenich · July 27, 2020, 2:09pm

Someone had mentioned there may be a motion sensor report for this device when it's on C-Wire. I'm not sure if that's true or not, since I don't have a C-Wire.

It doesn't look like battery percent is currently reading? I may file a PR for that later, if not

JasonJoel · July 27, 2020, 2:26pm

Battery updates when "refresh" is hit, but I haven't seen an unsolicited battery report being sent by the thermostat at all/ever - even for the few days I had it battery powered while writing the driver. But maybe I missed it? I'll look again... If it never sends one I'll setup a scheduled 1x/day battery refresh task in the driver.

I also have seen no indication that there are motion reports of any kind while watching 100% of the communication for the last few days.

Mine are c-wire powered, fyi.

Looking forward to receiving mine. This thermostat's configuration options permit finer grade control over staging than the Honeywell T6 does. The options are very similar to the ecobee - staging is controlled by the delta between the setpoint and ambient temperature. I like this - it will let me run longer in a lower stage to promote dehumidification.

The Honeywell T6 does it by restricting the number of cycles per hour and then uses some internal magic to pick the stage.

JasonJoel · July 27, 2020, 3:41pm

I'm not sure how the Honeywell is, but I like that the Vivint reports temperature in 0.5 DegF increments (the GoControl only reports in 1 DegF increments). You still can only set setpoints in 1 DegF increments (as far as I can tell - I didn't look hard, but the setpoint report indicates precision=0 which is integer), but it is nice getting half degree on the reports.

Having humidity reported isn't something I use in any automation, but hey... Free data.

I didn't spend much time on the multistage options (I only have 1 stage units), but there are definitely settings on degrees for stage fallback.

aaiyar · July 27, 2020, 4:16pm

The Honeywell can supposedly be configured to report increments of 0.5F.

I had never heard of these thermostats before, really nice looking. Tempted to get one now...

mference · July 27, 2020, 9:26pm

this looks amazing i am going to install the driver tonight I am using Celsius and will let you know if there is an issue! thank you very much!

Mark

JasonJoel · July 27, 2020, 10:38pm

I will say that the preference dropdowns are all in Degree F.... They will still work (as internally the dropdown options write integers like 1, 2, 3, etc) but the dropdown label will be wrong.

I'll have to research a little how other thermostat drivers handle this...

Until then, assume that any of the "degrees" options are half that when using C.

JasonJoel · July 28, 2020, 12:09am

V1.2 - 07/27/2020 - Added Refresh after 10s when configure button is pressed, Added scheduled battery refresh every 12 hours

mference · July 28, 2020, 12:43am

I have installed the driver and set up the settings, everything works good but it seems to reporting the temperatures in Fahrenheit even when it is set to Celsius, my thermostat heat set point is set to 18C but is reporting it set to 64.5 (which converts to 18.05 C) and 32 in google home (that is the maximum of the scale in Celsius) it is reporting the temperature as 80.5 and the thermostat is showing 27 (80.5F converts to 26.9C). when trying to set the heat set point in Celsius it will not accept any number below 35 that would be the 1.5c minimum in the thermostat.

I am sorry if this is confusing and way to much information, basically i am just trying to say that it is all in Fahrenheit for setting and reading.

JasonJoel · July 28, 2020, 12:47am

Argh. OK. Seems I may need to do an F to C conversion somewhere... Oops.

I think I know where/how, but to be sure , f you get time please turn on debug logging, change a setpoint, and send me the log entries.

Thanks!

JasonJoel · July 28, 2020, 1:10am

Thanks!

And I assume your units on the thermostat itself are set to C, right (probably a stupid question).

This might take me a day or two to sort out, but I'll get it. Might want to use the generic driver until then, though.

mference · July 28, 2020, 1:20am

yes it is set to C.

thank you very much!

Take all the time you want i appreciate having a driver that will allow me to set all of the settings and have a fan timer too!

JasonJoel · July 28, 2020, 1:29am

@mference
I just uploaded v1.3 that may fix this - I definitely found an issue when writing the setpoints. I think the reports already worked.

Give it a try and let me know!

If that works, then I'll go back and start thinking about how to improve the dropdown boxes for celsius users.

mference · July 28, 2020, 1:37am

it is now letting me set the thermostat in C but it is still reporting everything in F.

here is the debug if you want it.
