I've been using several code examples but I cant make my esp upload the ds18b20 data to thingspeak.
1) I tried both the api key and the write api key - which one to use?
2) In my router setup I'm setting a rule to forward the port 80. Is that correct or do I have to forward port 8080 in order to speak through port 80?
3) Do I set the router to port forwarding OR port triggering?
I just cant seem to make it work... thank you very much for your help!
