UbiMaker

Hello Hashmia,I made a test with the sample code provided and it's working properly for me. Note that the light will be turned ON just when the reading of the sensor es less or equal than 50, if you desire you can change this limitation in order to set the limit of your preference.Btw, we made an update of the library months ago, in order of this I made little modifications into the code. All the best,Maria C.

Hello!You can reference to this example(https://github.com/ubidots/ubidots-mqtt-esp/blob/master/examples/subscribe_and_publish/subscribe_and_publish.ino), this example will serve you to publish and subscribe to/from Ubidots. Modify the example above with your parameters, also with the example provided in the project. To give you a better idea, you have to publish the temperature value and subscribe it to a new variable(the fan), this variable have to be create before upload the code into the device. Then, you can use the Ubidots Events as we did it in the project but instead of "send a e-mail" select "Set a variable" and select the variable that you subscribed it (the fan). So, when the temperature reaches the limit, set the value "1" in order to turn on the …

Hi there! the tutorial is about controlling the module over WiFi == Internet == Remotely. The cable in the picture is only for programming it the first time.
