v.2.3.0

Merging two sketches that had both been released publicly with the same version number:

v2.1: Factory test transmission moved to Grp 1 to avoid interference with recorded data at power-up. [RW - 30/1/21]
v2.1 (duplicate): printTemperatureSensorAddresses() was inside list_calibration() - reason not recorded [G.Hudson 23/12/21]

The duplicate was used by the OpenEnergyMonitor Shop; the original (RW's) was released on the OpenEnergyMonitor forum: https://community.openenergymonitor.org/t/emon-devices-factory-testing-transmissions-of-zero-values/16683/11.

v2.1.0

• Fix temperature sensor status in serial print

v2.0.0

Power & energy calcs using "Assumed Vrms" added, serial output was switched off when rf output is on.

v1.9.0

• Unused variables removed

v1.8.0: Signed Long energy values

Requires corresponding change to emonhub.conf to read signed long values:

[[15]]
  nodename = emontx3cm15
  [[[rx]]]
    names = MSG, Vrms, P1, P2, P3, P4, E1, E2, E3, E4, T1, T2, T3, pulse
    datacodes = L,h,h,h,h,h,l,l,l,l,h,h,h,L
    scales = 1,0.01,1,1,1,1,1,1,1,1,0.01,0.01,0.01,1
    units = n,V,W,W,W,W,Wh,Wh,Wh,Wh,C,C,C,p
    whitening = 1

v1.7.0: Check radio channel is clear before transmit

Check radio channel is clear before transmit, thanks to @robertwall

v1.6.0

Removed reliance on full jeelib for RFM, minimal rfm_send fuction implemented instead, thanks to Robert Wall

V1.5.0

• Faster RFM factory test

V1.4.0

• Ignore old emonTx V3 discrete sampling firmware EEPROM config
• Add more error checking to EEPROM config
• Add option to save RF_freq to EEPROM
• Enter config option before RFM init
• Streamline startup sequence

V1.3.0
