It's easy to burn out when working from home. Try to establish bounds, and resist urge to e.g. work for whole day doing long breaks during the day (e.g. from 8 to 12 and then from 16 to 20) if you do this for prolonged period of time you'll feel as if you are working non-stop.
Keep in mind that temporary productivity loss is expected. Some permanent productivity loss may be expected. Major productivity loss if you need to care for dependents when working from home is expected.
TL;DR; Try to do your best when working from home, but try not to worry too much.
There is a lot of advice for Working from Home, but mind that some things works from some people, but not for others. Need to work in a formal wear, do it!, can work in pyjamas also it's fine.
There IMO the most important thing:
You need to communicate more proactively, and in general: you need to communicate more.
How it depends on a team. I started doing written recaps of daily work, right now I add notes to each issue I work on a given day.
