We wonder if there is anyway to do an "advance" password change.
Situation: We have some pi zero's in the field. They are connected via wifi. We can ssh into them.
Sometimes the location where they are at changes the wifi password. We have advance notice, and it would be nice to be able to ssh in while they are still connected and the wifi password hasnt changed, and schedule or do something that would make it use the new password when it changes.
Thanks in advance for any ideas.
