Sensor number * 256 + 1. Sensor number
for RH is Modbus address + 2. For example
C N
an IAQPoint2 at Modbus address 005 will
appear as 1793 or 0x0701.
C N analog_input (0)
if temp sensor fault, fault (1),
R N
else normal (0)
"IAQPoint RH AdXXX .RH" where XXX is

the Modbus address plus two.
R N FALSE
R N Relative Humidity in percent
