enc82j60 is Ethernet controller I want to interface that with my arduino and send some sensors data to firebase. Now are there API's or libraries to send values(integers,floating) to firebase just as we do in ESP8266. I tried finding but, it's only for thingspeak.com and not firebase.
It shouldnt be that different. When you send data to thingspeak, you are just sending http GET requests. Writing on firebase should be somehow similar, investigate if firebase accepts http requests.
