MQTT data manipulation
#1
Hi,

I'm building a network interface to get data from my engine (RPM, coolant temperature, oil pressure) to OpenPlotter. (Just for the purpose of displaying it with KIP). I thought the easy way to go would be MQTT ...

So I build an application that posts the data to an local MQTT broker (localhost on the RPI running OpenPlotter) So far so good. Everything works like a charm, I can see my updates in the Diagnostic Signal K input window. 

Problem is however the data transmitted over MQTT are treated as text variables and i can't select the fancy gauge's in KIP to display my engine data. 

I guess my question is; is it at all possible to convert the MQTT data back to numeric data for display in KIP? 

I'm using an RPi-3, the interface connects over WiFi

Kind regards,

Koen
