Hi, There must be a simple answer to this can any one help please? I have a DSI8B20 temperature sensor which is measuring water temperature.I want to ask Alexa to tell me the current temp.I have set up the Alexa virtual device in node red and running the pizza oven example(node-red-contrib-virtual-samart-home) it works fine.The pizza virtual device node needs the object - temperature:(temperature as a number) The DS18B20 only gives the temperature as a number. What node would I need to use to make this object and what would be the settings. I have tried many combinations with the change node with no success.
