hello everyone, i am totally new to this kind of stuff and about to learning.
i have followed the WiDo IoT Tutorial and able to send a single moisture sensor data variable, but i don’t know the syntax how to control relay (on/off the actuator) from Ubidots.
I am bout to make an automatic irrigation system with soil moisture sensor, when sensor detect dry soil, the water pump is on. Ubidots is for monitoring. For emergency situation i want to make on/off control for the water pump.
Please Help me…
