Wunderground Luup Code

I am writing Luup code to make changes to thermostat set point based off of outside air temp as recorded using the Wunderground World Weather app.

Having spent hours debugging can anyone help?

local lul_temp = luup.variable_get(“urn:schemas-upnp-org:device:HVAC_ZoneThermostat:1”,“CurrentTemperature”, 8)
if (tonumber(lul_temp) > 26.6) then
return true
end

thanks

You don’t want to be using the device type [tt]urn:schemas-upnp-org:device:HVAC_ZoneThermostat:1[/tt] in the[tt] luup.variable_get[/tt] call, you instead want to use the service ID [tt]urn:upnp-org:serviceId:TemperatureSensor1[/tt].

Also what are you returning when not returning true?

Sorry to bump this thread, but the function : tonumber(), it is the LUA function as with Modulo in C++?

[tt]tonumber()[/tt] is a Lua built-in function that tries to convert an expression to a number, as in this case where it is passed a string (or [tt]nil[/tt]). If the string meets the format of a string, [tt]tonumber()[/tt] converts it to a number so you can use numeric comparison operators. See http://www.lua.org/manual/5.1/manual.html.
