I'm getting following error while compiling, any solution?
@FotoFieber I followed the sketch that you provided in your link above called "MQTT Client Gateway". however, while compiling that sketch I'm getting following error?
Any solution or suggestion for that?
I'm trying to receive battery percentage over MQTT on openHab. So far i'm dont have any luck. I'm confused, because there is no such V_Battery or something like that.
I would really appreciate any help as i'm trying to finish my project before my final exam starts.
Here is my serial output. I was testing the battery sketch on Nano powerd via USB 5.0v. I know i'm getting incorrect reading, but thats okay for now, I just need to receive battery percentage via MQTT first.
