Setup 3-phase emonTX with emonESP using emoncms.org

Hello Peter, that looks like a very useful guide. I want to end up with exactly what you have done but in the UK - that is 3-phase, emontx-EmonESP-emoncms.org. I currently have the standard emontx 3.4 and shop supplied WiFi add on setup for single phase with 4x CTs. I discovered that this does not give correct results on 3-phase (see EmonTx Input labels - confused new user - #10 by borpin )
Is there some easy (ie lazy and needing very limited technical knowledge!) way to get my hardware loaded with the necessary firmware to operate correctly on 3-phase?
