Overview
The mFi-THS also has a humidity signal on pin 2 of the RJ45 port, and pin 1 is grounded, allowing these signals to be connected to pins 3 and 6 respectively of an additional mPort RJ45 port (or A+, A- of the terminal bock).

Custom Sensor Definition
Store this file as <mfi root>/build/dl/custom.json Or if that file already exists, add the contents to the existing file according to the custom sensor document.
{
"Ubiquiti mFi-THS : Humidity" : {
"desc" : "Ubiquiti humidity sensor (need to route pins 1 and 2 of MFI-THS to pins 6 and 3 of the mPort RJ45 connector, or A+ and A- of the mPort terminal block)",
"conversion" : "xyz*50",
"analog" : true,
"rj45_v1" : true,
"tblock_v1" : true,
"pwr_volt" : 12,
"rep_analog" : 1,
"default_tag" : "humidity",
"analog_tag" : "humidity",
"unit" : "%",
"precision" : 2
}
}
Note: this configuration also sends power out, which normally is not connected to anything when used with the temperature function. This allows this definition to also be used stand-alone, for humidity only.
