I tried using this on ESP8266 nodemcu but facing multiple issues.
Unable to connect to the board post uploading the code.

I post my API key and connect to the BB monitor app in sketches but i am getting an error when i try to download the ESP sketch


When i run the server locally, the temp sensor works fine but the when i try to trigger the relays, i am getting an error.

I have raised the same issue in your github repo.
