I’m using WebCore and have CT101s, so not sure if this would work for you. But what I did in my thermostat schedules is have it check a virtual switch’s state and if the “Thermostat Hold” switch is on then the schedules don’t run. I use this in conjunction with two other Momentary Tile virtual buttons – one triggers “Home Hold” and the other “Vacation Hold”. Basically, push the momentary button and it sends temp commands to the thermostats and then turns on the Hold button.
Hope that makes sense.
