Change log:
V3.1.0 - 18Oct16 test for RFM69CW and SI7201 at startup, allow serial use without RF prescent
V3.0.0 - Oct16 Add support for SI7021 sensor instead of DHT22 (emonTH V2.0 hardware)
V3.2.0 - (13/11/16) run-time serial nodeID config
V3.1.0 - (19/10/16) Test for RFM69CW and SI7201 at startup, allow serial use without RF prescent
V3.0.0 - (xx/10/16) Add support for SI7021 sensor instead of DHT22 (emonTH V2.0 hardware)
^^^ emonTH V2.0 hardware ^^^
V2.7 - (15/09/16) Serial print serial pairs for emonesp compatiable e.g. temp:210,humidity:56
V2.6 - (24/10/15) Tweek RF transmission timmng to help reduce RF packet loss
