Here’s how to add a read-only feed of Cozi events in DAKboard. Note: this must be done on a desktop computer.
Sign in to your Cozi account from a computer
From Calendar, click Set Up: Share appointments:
Click Not shared next to the family member whose calendar you’d like to share. (Two options pop up: Not shared and Shared. Select Shared.)
You can select an individual family member or All family members for this feature. (If you want to share feeds for multiple children, you’d need to select each child individually and create separate feeds for each.)
Click View URL and copy the link:
In the DAKboard settings, for Predefined screens: click on Screens > My Predefined Screen > Calendars. For Custom Screens, add a calendar block, click on the block to select it and click the Edit button. Paste in the link and click "Save Changes".
