Would the Davis 6100 be considered an alternative to Wifilogger?
Yes
How do they compare and contrast?
They are similar in some ways and different in others
. It does depend on exactly what you want to do, both now and potentially in the future. And it's not easy to summarise all the features in a short post.
Weatherlink Live (WLL) is a completely separate receiver to the console (indeed there's no need to have a console at all with WLL) and can be positioned wherever you like as long as it sees an ISS signal and a network connection.
WLL's main role in life is to upload data to the Davis weatherlink.com platform and its whole design is focused around this. That said, it is possible to receive WLL data on another local computer, eg a Raspberry Pi running CumuluxMX, but obviously that entails running a separate computer, which some/many users may be trying to avoid. If you're happy focusing your data handling around weatherlink.com then WLL is the official and perhaps the best option.
WLL also has another standout feature in that it can receive data from any mix of transmitters on all 8 wireless channels, ie it is much more flexible than a standard console. But if all you want to do is to receive data from a Vue ISS then this flexibility is irrelevant.
One important limitation of the WLL unit is that it cannot store archive data in a form that's readily accessible by other local computers.
(Edit: To accommodate Brian's comment below: If you have a Pro plan ($50pa) at weatherlink.com then archive data may be available as a download from the weatherlink.com platform to external software, but this is not the same as the archive being stored directly in the logger, as WFL can do)In most other respects the WiFi Logger (WFL) is a good option and arguably with wider applications than WLL. Specifically, WFL is significantly cheaper than WLL (which will be a big factor for many users) and can upload
direct to a range of online platforms like WU (including RapidFire), WOW (and also - with the small caveat that this is an unofficial upload - weatherlink.com) etc.
WFL is similar to other Davis loggers like the USB and WeatherlinkIP parts in that it fits inside the console, rather than being a completely separate part like WLL. So WFL becomes an integral part of the console and takes all its power from the console.
In other words, WFL is a fully self-contained solution for making online uploads and requires no external computer running, though WFL
can also connect as a network logger to a wide range of software running on another local computer, if that's your preference and you do want that added functionality.
Guess that's it in a nutshell for the main considerations, but there are numerous other pros and cons to each. Ask if you have follow-up questions.
