* Add support for expiring retained messages.
For most of my environmental monitoring use cases, I want the readings
retained so I can pick them up from clients at any time, but if the
sensor (or zigbee2mqtt) fails, I want the readings to go away so I can
tell the difference between a stale reading and a missing reading.
This is easily accomplished in MQTTv5 using the "message expiry
interval" property. To add that to zigbee2mqtt, I added a 'version'
option to the mqtt section so I can specify to connect with version 5
and added a 'retention' property to devices allowing me to specify how
long items should be retained.
e.g.
mqtt:
base_topic: site/zigbee2mqtt
server: 'mqtt://myserver'
user: zigbee
version: 5
serial:
port: /dev/ttyACM0
devices:
'0x00358d00022308da':
friendly_name: someroom
retain: true
retention: 900
* Also get from deviceOptions
* Update settings.js
* Update controller.js
