The nest Thermostat will heat your home for 30 minutes of a pre defined schedule before checking if it is set to away. If the Nest Thermostst is set to ECO then this does not happen.
If you use the Nest Thermostat set to Eco when away this does not stop the nest heating for 30 minutes before checking
When home / away assist is off in the nest, skylark cannot set the Eco mode on. It sets away, but that's it. Needs the api integration updated to set Eco also, other products like wink have done this.
