Manage ZWave Direct association from DZ

[rezzalex]

Hello,
ZwaveJsUI propose APIs to act remotely.
As I shutdown my Host every night, I would ike to associate directly a PIR with a LIght only during nights, which implies making the association just when DZ is shutdown and removing it at start up during the morning.

It seems ZwaveJSui are managable thought MQTT messages.
How can I send specific MQTT message from DZ ?

Domoticz is not meant to be shut down every night. It even could will give some issues as at 0.00 hrs there is daily database maintenance.
Why shutdown Domoticz and keep ZwaveJSUI and MQTT running?
