Re: [weewx-user] Re: Attempting to use a Pete Bros. Ultimeter2100 on a RPi3 with a serial to usb converter

[Ralph Underwood]

I installed the station last week and it appears to be working. I managed 
to break the anemometer while I was installing the mast so I have no wind 
info until my next visit to the site in a week or two. Pete Bros. had the 
parts available and I already have them in hand.  I ended up commenting out 
all of the one-wire stuff for my extra temps as I was getting some weird 
readings from two of the sensors and I figured it would be easier to 
troubleshoot in my "lab" than on-site.

May I add one remark: Look at the odroid-C2. As cheap (or cheaper) than 
the raspberry, faster, with more memory and the choice of using eMMC 
memory (together with a micro-sd). I use it since February and, except 
an unlucky software glitch, works without a problem. Moreover it has 
ubuntu 16.04 LTS which is in my opinion more stable than raspbian (or 
debian).

I started out running Weewx on a Ultimeter 100, but the upgraded to 
the 2100. The 2100 system has been up and running since July 2015 with 
no hiccups.

I have a serial to usb converter as the Rpi does not have a serial
port and I somehow missed that the Ultimeter was not USB when I
ordered it.

I tried to use this in my weewx.conf :



##

[Ultimeter]
# This section is for the PeetBros Ultimeter series of weather
stations.

# Serial port such as /dev/ttyS0, /dev/ttyUSB0, or /dev/cuaU0
port = /dev/ttyUSB0

# The station model, e.g., Ultimeter 2000, Ultimeter 100
model = Ultimeter

# The driver to use:
driver = weewx.drivers.ultimeter

[Ralph Underwood]

I'll second that, great support from users and developers!  

This is the third weewx station I have cobbled together - one with a 
wireless Oregon Scientific, one with one-wire, and now this one with Pete 
Bros. - Plus two more carefully monitoring my basement as I test and 
experiment. The Rpi price makes all of this possible, just skip a couple of 
Starbucks visits and you can buy a computer.  I now know just enough Linux 
to get things going and it is fun learning.

The wireless station looses connectivity too often. That station is located 
near I-90 and I suspect that there is some powerful interference from the 
truckers radios as well as some nearby state radios. Just a suspicion, 
everything worked fine when it was twenty feet away in my workshop, but in 
the field not so much. So I wanted a wired system for my new system to be 
installed at my vacation home. With the demise of Hobby Boards; I was 
looking for an alternative to one-wire. I still plan on adding some 
one-wire sensors to this installation as I have a bundle of temperature 
probes.

Thanks again to all of the supportive users.

Thanks, that got me to a point where WeeWx is running and the log says it 
is ftp'ing. Nothing on the web page. 

Have to go to work for a while and then I will attack it again.

Thanks.
