Humidity sensor(s)

[Jason Sipula]

I inherited a system with 2 1-wire sensors using Digitemp 3.5.0. It's been running this way for years perfectly well.

Recently we had some A/C issues in our server room that have caused me to realize our two sensor setup wasn't the most accurate. So I've added two additional sensors that do temperatures and humidity, the MS-TH (also added a few other temp. only sensors that work fine):

We use the Link45 as the connector to the linux box. I had ordered a LinkTH connector since the website suggested that it was able to read humidity and the Link45 was not?

I wired them all up and replaced the Link45 with the LinkTH. I can not get the LinkTH to be read. I get the "Adabter cannot be found" general error and nothing I do will fix it (even downloaded Digitemp 3.6.0, unzipped and did the .

# /digitemp_DS9097U -s/dev/ttyS0 -i 

same error. If I put the Link45 back, I can read all the new sensors including the humidity sensors that show a % humidity as follows:

digitemp-3.5.0]# ./digitemp -a

Apr 30 15:35:47 Sensor 9 C: 19.31 F: 66.76 H: 38%

So I have humidity and temps being red from the same sensor... perfect!

But when I check the database, not so perfect. It seems that both humidity sensors have been lumped into a single sensor called "Apr". And the only measurement being logged in the database is "30"... constantly... regardless of whatever 

digitemp -a gives me.

Heres some database entries:

What is going on? How can I log the measured humidity!?!?! This is driving me crazy!

Thanks!
