I now use my esp8266 send values to ubidots and I can see some nice temperature readings.
No I have hardcoded a function that triggers a relay when the temperature is higher than my setpoint. And kicks off again when temperature is lower than a setpoint-deadband.
I can adjust the "SETPOINT"and “DEADBAND” through some buttons on my LCD keypad shield, but also want to do this remotely. Had hoped that I can send commands from the ubidots site, but don’t know how. And also did not find a tutorial with similar things.
Any advice is more than welcome
