There are a lot of users that use the device tracker / known_devices to indicate if a device is online/offline. Currently to change from home/away you need to set up the customisations.
I just had the idea while I was editing known_devices to add some icons, that it would be nice to have two additional attributes in known_devices - home / away, where you could customise the text.
For example
phone:
hide_if_away: false
icon: mdi:cellphone-android
mac: AA:BB:CC:DD:EE:FF
name: Dave
picture:
track: true
vender: AN OTHER
home: Home
away: Away
tv:
hide_if_away: false
icon: mdi:television
mac: AA:BB:CC:DD:EE:FF
name: Lounge TV
picture:
track: true
vender: AN OTHER
home: On
away: Off
laptop:
hide_if_away: false
icon: mdi:laptop
mac: AA:BB:CC:DD:EE:FF
name: Laptop
picture:
track: true
vender: AN OTHER
home: Online
away: Offline
vpn:
hide_if_away: false
icon: mdi:vpn
mac: AA:BB:CC:DD:EE:FF
name: Work VPN
picture:
track: true
vender: AN OTHER
home: Connected
away: Disconnected
Just an idea anyway
