Easy MQTT Graphing

I’m quite excited this morning, had an email from Kamil Baczkowicz – could I please try the latest beta of MQTT-SPY – I’ve been encouraging him to add graphing for the MQTT input as even Node-Red doesn’t do this out of the box.. sure enough he’s cracked it. Here’s a working example, I have my DS18b20 running so that it returns the temperature from my little ESP8266 board every 5 seconds. I got up this morning, loaded the new BETA of MQTT-SPY and…

I just keep getting more impressed by the fast, simple package. It’s a .JAR file incidentally so whatever operating system you’re on you’ll need JAVA installed but that seems to be pretty universal except (and I’ve never figured out why) the mobile operating systems such as Android. If anyone figures out how to get this working on an Android tablet, you will be my best friend ever if you report back in here.
