I am struggling with getting my sensor data over to Blynk. I have a Wireless Gateway and a Bidirectional Pressure/Temperature sensor. In node red, my debug node shows the temperature and pressure data as expected. I have also been able to setup the MQTT Out node in node red and have it connect to Blynk.
How do I parse the data from the wireless gateway to only send the temperature? From an example on the Blynk website ( NCD Environmental Air Quality Sensor ) they appear to use a function node with a bunch of code within it, which I cannot decipher.
Is there a simple example of how to do this?
