Lockdown

If the space needs to go on lockdown for whatever reason (it should be a good reason!) here is a checklist:

set the front door status to "lock" on the omnisectech website (not many people have the password to this site). This prevents any sort of unlocking with cards or codes
disconnect gatekeeper's power
mute cardkey's notifications to prevent communication of activity within the space
disable homeassistant automatons that signal when the space is open / has activity within it.
