For anyone that might be interested: We're currently trialling a Davis
6555 WeatherlinkIP logger. (If you've missed previous posts, this is a
new Weatherlink logger with an IP interface, meaning that it can be
plugged in directly to an Intenret connection.) I'll post some more
details once we've accumulated a bit of experience,

Davis seem to have decided to release this part more quickly than I
anticipated just a couple of weeks ago and it should be available here
hopefully within the next 2-3 weeks. Haven't got an official price yet
but apparently it will be the same as the other specialist loggers eg
6550.

You can see our data on the central Weatherlink website from this test
installation at:

(NB This is only a test at our end at this stage and so the live data
may be limited and intermittent.)

That sounds very interesting. Let me know when you have more information
on this.

I'd be particularly interested if the IP logger can be used without the
weatherlink software. This would save me having to keep more than one
computer on all the time - especially if I can retrieve the data
remotely (my VP is still in Canterbury as a friend lives at my old house
but I have to keep a computer on there to retrieve the data over the
serial port and upload it to my own database).

The answer is yes to that, though with caveats.AFAICS the 6555 logger
will (initially at least) have two modes of operation.

One will be passing data locally to the Weatherlink software (v5.8 -
not yet formally available) in the familiar way.

The other will be uploading data directly - ie with no need at all for
a local PC, just an Ethernet connection to eg an ADSL/cable router -
to a server at Davis, which is what our test is currently doing. As
well as being able to view your data online in the standard Davis
format, it will then also be possible for you to download archive data
records (but not loop data, which won't AIUI be stored centrally) from
the Davis server. So the Davis server can in a sense be used as a
proxy source of the archive data.

In time there might be other modes of operation possible but it's
premature to speculate about that at present.

John,

Out of interest, is this a wired conection to the internet, or wireless ?

It's a generic TCP/IP connection. Typically it would be behind a
router of some sort but that router can be any flavour that can
establish a route to the target server for the data (ie currently the
Davis data server). So it can be cabled or wireless.

The demo that we have running currently is just behind a standard
office Draytek ADSL router but in principle anything appropriate
should be able to do the job, though obviously there might be some
practical details to sort out for more exotic hardware. To be clear,
you can't attach it directly to an ADSL-enabled phone line - there has
to be some sort of routing box that it plugs into, but any common and
inexpensive sort of modem/router providing an Internet connection
should suffice. If you're interested in any of the more technical
details then maybe contact me offline. Email address is valid.

John,

I looked at the faq but didn't see an answer to my question, namely how
much data is transfered each minute? I would like to know the ball park on
this to see any possible impact on my data limits with my isp. Do you know
the value?

Cheers

Sky.

The details of the data formats used on the WL IP link haven't been
disclosed by Davis yet and so I can't answer definitively.

But the data could be just one loop packet (or perhaps an averaged
version - over 60secs - but still in loop format) in which case it
would be around 100 bytes per minute (ie 6K/hour / 144K/day /
4.3MB/month). Even if a new format is being used (ie not the existing
loop format) there's no reason in theory why the total should be more
than 100 bytes per upload, indeed it's possible to code the key
current conditions in much less than 100 bytes.

Any archive data transfers would be additional to this and the size of
these would depend on what archive interval was set, but worst case
would perhaps be the same again in round numbers, or say 10MB in total
per month. I can't see this impacting much on most ADSL/cable
allowances though you might have to be more careful when checking the
impact on any cellular (ie mobile phone) Internet link.

JGD

John,

I can certainly live with only 10MB or so! I also note that you can set the
upload to longer intervals than 1 min so if there was a concern you can do
less frequent updates...

Cheers,

Sky.

Very timely John! Was just thinking I ought to be looking for an
RS232-Ethernet adapter for more flexibility on my home network. The new
laptop I just bought to run KnaresboroughWeather might be taken away
from base in future, so I would temporally transfer duties to an old
desktop machine elsewhere in the house. (Although, duh, I could just
move the console!, though ISTR recall reception was v poor in the
"office")

I think Phil was asking what the logger uses to talk TCP/IP over. ie is it
a wireless device requiring a wireless network or does it just have a bog
standard ethernet port. I get the feeling it's the latter.
