Module "urn_schemas-upnp-org_service_SwitchPower_1
"
Standard service; "urn:schemas-upnp-org:service:SwitchPower:1". When required, it returns a single function which generates a new service table on every call (it takes no parameters). The upnp.devicefactory
module takes the device/service tables to build device/service objects.
Requires to implement the following elements;
service.serviceStateTable.Target.afterset = function(self, oldval) ... end
to process the changed Target value
Functions
afterset (self, oldval) | Implement this handler to add SwitchPower capability. |
Functions
- afterset (self, oldval)
-
Implement this handler to add SwitchPower capability. The handler should implement the actual switch behaviour and set the 'Status' variable to the new value when done.
Parameters:
-
self
: statevariable object for the 'Target' statevariable -
oldval
: the previous value of 'Target'
Example:
-- Create a new SwitchPower service
local service = require("upnp.services.urn_schemas-upnp-org_service_SwitchPower_1")()
-- add implementation
service.serviceStateTable[1].afterset = function(self, oldval)
-- do something useful here...
print("Setting the SwitchPower value to", self:get(), "from", oldval)
-- When done update value of Status to reflect the change
self:getstatevariable("status"):set(self:get())
