I have a CT80 with zwave control. Works well, but auto-creates four climate entities, heat_normal heat_econ, cool_normal, and cool_econ. Only difference is the default set-points between econ and normal. All other attributes and state values are the same across them all. So, I use the custom:Dual-Thermostat lovelace card to switch between heat_normal and cool_normal climate entities.
I also created two custom sensors, one for Operating Mode and another for Operating State. These are useful for automations, etc. Here’s the code:
#~~~~~~~~~~~~~~~~~~~~~~~~~
# custom sensor that tracks the mode set for the HVAC.
# This reports what its set to, not what its doing.
# All of the four CT80 "climate" entities show the same properties
# Use "heating" because its now wintertime, no other reason.
# While the fan could be forced on during non-off modes,
# only report "fan" as mode when system is otherwise off and fan is on.

# custom sensor that tracks the operating state of the HVAC.
# This reports what its doing, as opposed to what mode is set.
# Report Fan-only if fan is running and the system is neither

Oh, also I refresh the status of the thermostat ever five minutes with an automation. Polling only updates the set-point, not all the attributes, or the state.
#~~~~~~~~~~~~~~~~~
# Refresh thermostat information
# CT 80 is not good at self updating when its state changes
# This will refresh every five minutes
# Note that it takes about 3 seconds for the thermostat
# to update once requested.
