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.

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?

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.
