I wasn’t linking to “IFTTT” app. I was using the IFTT within SmartThings applications.
It went like this
IF it’s 430PM, THEN control the thermostat, set target to 68, set FAN to Auto, set to HEART
It was intermittent, tech support has been so bad and slow (it used to work!), I gave up and replaced the CT101 with a new Honeywell thermostat. It interfaced with SmartThings smooth and easy. Now I gave a Honeywell app and or can control the thermostat via SmartThings.
(www.rboyapps.com - Making SmartThings Easy!)
The CT-101 has a two modes of operation, the simple mode and the regular mode. Is it’s set to simple mode (i.e. using the built in scheduler) then it disables many z-wave operations.
Regarding the CT-101 clock, it will synchronize only if the device handler synchronize the time.
If you’re using the Honeywell Z-Wave thermostat take a look at this Enhanced Z-Wave thermostat device handler which will enable the hidden Auto mode in the thermostat (like the CT-101). The same DTH will also sync your CT-101 time and allow you lock/unlock the controls on both honeywell and ct-101 through SmartThings:
