I read somewhere that in order to turn any routine(e.g., standups) into a habit you need a little immediate reward that comes after that routine. That means you need to think about giving some kind of reward even if it is little like snacks, candies and so on. So, this is the psychological solution.
Technological solution would be to conduct standups remotely by using something flexible like this. This is a Slack bot called Comedian.
Good luck!
