How can I save a string in a variable in ubidots and how can I read values from Zerynth using esp32? I’m using MQTT
Greetings, yes. You should send your string text inside a key of the dot’s context. For more information, please refer to our docs.
All the best
Thanks. How can I read values on Zerynth from Ubidots?
Example: I want to turn on a led on my board with a widget in Ubidots’ Dashboard using MQTT
