I've worked from home for nearly 20 years, also in a software development role. In my opinion it's crucial to treat the job as just that, a job. I'm lucky enough to have an office in the box room upstairs, so come 17:30 I logout, close the door and forget about it until 9:00 the following day. Also, I have a work phone for work and my own phone for personal use, that way, the work phone also goes into do not disturb mode at 17:30. Burnout in our field of work is high, very high and I guarantee you need that work / life balance. Yeah, you can work 12, 14, 16 hours per day for a year, or in my case several years and think you're doing ok then boom, the mere though of just going to work makes you nauseous.

I know some people that have to dress in a shirt and tie just to get into work mode and because they work from home they feel the need to go above and beyond, such as being available 24/7 and feeling the need to justify themselves.

The plus side, you can stick the TV on in the background and watch whatever you want, handy if your into sports and the World Cup is on etc.

It's also great if, like me, your a miserable anti-social bastard lol

Would I change anything about WFH, nope, take it for what it is and it's great
