You need a commute. It can't be a physical "get in a car and drive to work" type of commute for obvious reasons, and so you need another way to signal to your brain "Hey, you're now getting away from the working process."
It can be as simple as walking away from the computer for at least 30 minutes. Turn off your phone, tablet, monitors, and what not. Don't sit down and watch TV. Give your brain time to make the transition.
I've been WFH since 2011- and at first it was a disaster for similar reasons. Once I set a routine that meant walking away from the computer for a while, I could come back and my brain had shifted gears a bit, and I could go on with my day.
For me it's as simple as getting off work and making a meal, then sitting down and watching TV after I made the meal, and in a different room than my computer.
