If I ever got a vacation, I would have thought of this previously.
I'm hoping someone has a better plan than I do. But, I'm thinking that this will need a virtual switch, "On Vacation / Working Like A Dog" and then a bit of Luup code in each scene(pain) to test if the virtual switch is set to On Vacation.
Untested, let me know if it fails.
local ID_VSWITCH = 55
local VSWITCH = "urn:upnp-org:serviceId:VSwitch1"
local VacationMode = luup.variable_get(VSWITCH, "Status", ID_VSWITCH)
if (VacationMode == "1") then
return true
else
return false
end
