Node ID for EmonTx5 with Expansion Board

Hardware emonTx
1

This is more an FYI for future users (or myself) as I cant find it documented. It appears EmonTx devices with expansion from 6 to 12 channels are programmed to have the first 6 channels as Node ID = N and the second 6 channels then got Node ID = N+1.

Therefore if you already have node ids used 27,28 and 29. Youll need to set the node id of the additional unit to 25, so that it will automatically assign the expansion board as 26.

Hi @macrowe777 - definitely better for most users to be in the text documentation, but it’s described in the source file.

I’ve just answered his first post about this (indirectly). I wrote and documented the library, Trystan used my example sketches to write the default ones.
