31 - Special allocation in JeeLib RFM12 driver - Node31 can communicate with nodes on any network group
-------------------------------------------------------------------------------------------------------------
Change log:
V3.2.5 - (20/09/21) Option for multiple external temperature sensors
V3.2.6 - [30/9/21 - RW] Multiple external DS18B20 sensors accepted. No change to config file.
V3.2.5 - [30/1/21 - RW] Factory test transmission moved to Grp 1 to avoid interference with recorded data at power-up.
Missing declaration of showString( ) added.
V3.2.4 - (25/05/18) Add prompt for serial config
V3.2.3 - (17/07/17) Fix DIP switch had no effect
V3.2.2 - (12/05/17) Fix DIP switch nodeID not being read when EEPROM is configures
V3.2.1 - (30/11/16) Fix emonTx port typo
V3.2.0 - (13/11/16) Run-time serial nodeID config
V3.1.0 - (19/10/16) Test for RFM69CW and SI7021 at startup, allow serial use without RF prescent
V3.1.0 - (19/10/16) Test for RFM69CW and SI7021 at startup, allow serial use without RF present
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
@ -48,9 +50,12 @@
v2.2 - 60s RF transmit period now uses timer1, pulse events are decoupled from RF transmit
v2.4 - 5 min default transmisson time = 300 ms
v2.1 - Branched from emonTH_DHT22_DS18B20 example, first version of pulse counting version

emonhub.conf node decoder:
See: https://github.com/openenergymonitor/emonhub/blob/emon-pi/configuration.md
NOTE: If the number of external temperature sensors is changed from 1, the 4 lines below: 'names = ...',
'datacodes = ...', 'scales = ...' & 'units = ...' must be changed to suit.
The maximum recommended is 4.
