What is a Scene¶
A Scene is a sequence of commands that perform one or more functions. These Scenes are coded with a scripting language called: Lua. Each Scene may act on a Node, a Variable, a Gatewasy or even on another Scene.
Smart Scene and Script Lua 5.1 Scene¶
Script Lua 5.1 Scene: example¶
In the Scene below, we get the Tag: Temperature from the Node with
- AppEUI: 0C00001104151763
- DevEUI: 0E7CD56433306500
Then we convert the Temperature into an integer type and compare it. If the Temperature is higher than 30, we call resiot_sendemail wich, obviously, send an e-mail with object and subject. If the Temperature is lower than 30, we set the value of the Variable "Temperature" to "The temperature is lower than 30°C" .
temperatureString, err = resiot_getnodevalue("0C00001104151763", "0E7CD56433306500", "Temperature") temperature = tonumber(temperatureString) if temperature > 30 then err = resiot_sendemail("email@example.com", "Temperature", "Hey, the temperature is higher than 30°C") if !err then resiot_debug("Error sending e-mail.") else resiot_debug("E-mail successfuly sent!") end else err = resiot_setvarstr("Temperature", "The temperature is lower than 30°C") if !err then resiot_debug("Error changing variable value.") else resiot_debug("Variable successfully changed!") end end
