Follow up question around updating the EmonESP firmware to work with an EmonTx running the 3phase firmware. I’ve seen you’ve gone [through this before](https://community.openenergymonitor.org/t/3-phase-in-austria/11389/34), but I want to make sure I haven’t missed something.

Is the only change I have to make to the EmonESP code is reduce the [Baudrate to 9600](https://github.com/openenergymonitor/EmonESP/blob/master/src/src.ino#L52)?
