I work in a mixed office, half in/half remote. I'm one of the few people (team lead/admin) that has to be in the office 90 percent of the working hours, which is fine. But I deal with good and bad remote colleagues over the years, so here's some suggestions.

Let me know when you are available, we have shared calendars and other means of indicating status, use them. Respect others time, both work and personal. If I can't get in touch with you for an extended period of time, let me know ahead of time or have a good reason afterwards. Let me know of any critical issues, technical or personal as soon as reasonably possible.

Let me know at you have on your project plate so I can assist or re-balance work loads if necessary. Please keep up with the "paperwork" aka source control, logging, reports, time-tracking and documentation.

If working remotely isn't working out, I've got some offices with doors and a fully stocked break room down the hall. And I'll throw in an extra monitor. :)
