Then @Barnaby_King would need to specify all his set-up options and the shop would need to compile and load his custom version in each of his emonTx’s. Have you made sure the shop is willing to do that? There would be hundreds of pre-compiled versions if every option were to be catered for. That’s why I don’t supply a compiled version, but always recommend that the user has a programmer and the Arduino IDE. They can then choose exactly the correct set of options for their application. Even when using the on-line settings, only a change of the NodeID and calibration is catered for, in accordance with the original specification.
I believe it is @Barnaby_King’s intention to configure and compile the sketch himself anyway - he already has seen the sketch and its documentation.
