I am using a nodemcu with arduino IDE
Am trying to setup a remote monitor of two temperatures sent via MQTT broker
If I use the examples, both the topics I subscribe to and their payloads print fine via serial monitor
My problem is I have no idea how to extract the separate payloads so I can process them to display onto OLED
anyone able to point me in right direction on this?
I should point out that the two topics I want to look at are published one after the other, with around 0.05 seconds between them, according to timestamp on MQTT spy
