Layout in doc image - mixes Master & Slave? #18

Closed jcjveraa closed 3 years ago

Hi Jiri,

Thanks for creating the project, I might try and copy bits for simply sniffing OpenTherm data with a ESP8266 based device (rather than implementing a full gateway). To that end I was looking at the electronics for the 'Slave', such that I don't need to think myself of what to do to safely implement that part :)

Could it be that this image mis-lables the Master & Slave? It doesn't make sense to me that the Slave would get 24V, or is connected to MASTER-IN/MASTER-OUT.

After sipping my coffee it clicked... But perhaps it would be an improvement to label the 'THERM' as 'THERM (MASTER)' for instance :)
