I have a Nest Thermostat and live in the UK. I have a radiator based heating system.
When I leave the house, some time later the Nest realises this and sets my house to Away. From this point onwards the thermostat does not obey any of my schedules. I have a schedule set to change the temperature at 5pm, but the nest ignores this because I don't arrive home until 5:30pm. At this point the house is cold.
I know that I can set the Nest to Home manually before I start my Journey, but is there any way to automatically have the Nest warm my home prior to arrival without disabling the Home/Away Assist or manually intervening?

You can use an application like Stringify on your phone to do this.
The application can be configured with a geofence around your home. As the phone is detected entering the fenced zone, i.e. you are approaching home, it can switch your Nest to home mode. Alternatively, set a fence around work and have it set Nest to home mode as you leave work.
There is a "Flow" to do this on their website. You can play with this to adapt it to your needs.
Alternative such phone apps include IFTTT and Zapier.
(Of course, you could also replace Nest with one of the competitor smart thermostats that do all this GPS phone integration automatically anyway.)
