Vantage Connect 2G/3G (Legacy)

The Vantage Connect is no longer manufactured, it has been replaced by the Enviromonitor System. This page has been left as a reference page in our ‘Legacy’ section.

Connect250wThe Vantage Connect unit is a relatively new addition to the Davis Vantage family. Connect allows automatic uploads of weather data from remote field sites to the Davis website at using a data link via the standard 2G/3G mobile/cellular phone network. Your live weather data may be viewed on PC or smartphone via a webpage or a fully detailed log downloaded to a Windows PC.

Connect itself is the white shelter fronted by a solar panel & midway up the pole in the image (right).

A sample webpage image of current weather conditions is shown below (at reduced size). You would be able to see data exactly like this from your own field site (live and updated every 5-60 minutes, depending on data plan chosen) with your own Connect installation. Additionally, you can download a data log at regular intervals to maintain a fully detailed database of all your own weather readings.

Extra features such as alarm emails (which can be transmitted as smartphone text messages via a suitable account) and automatic uploads to online weather networks such as Weather Underground are also available. A short overview video of all the main features available at the Davis service is available at or in a longer and more detailed version at

Key facts: With Connect, it’s now possible at relatively low cost for real-time weather data to be measured at any remote site (with no facilities required other than mobile phone reception) and then viewed via the central Davis website on PC or smartphone from any location worldwide and with readings updated every 5 to 60 minutes. There A full database of all readings from the site can also be maintained via Internet download to any Windows PC.

The components of a Connect installation

The schematic below illustrates the flexibility of a generalised Connect installation. The Connect unit can receive data from the full range of standard VP2 wireless transmitters, such as a regular ISS main sensor unit (even a Vue ISS), a supplementary temp/hum transmitter and a multi-sensor soil/leaf wetness station. So, to reiterate, Connect is an add-on unit for separately-specified Davis Vantage sensor transmitters; the standard Vantage sensor units generate the weather readings as usual, while Connect provides the remote data-link capability.

connect_schem600In the simplest configuration (i.e. receiving data from a standard Vue or VP2 ISS), a Connect unit will therefore report readings for:

  • wind speed and direction;
  • air temperature and humidity;
  • pressure;
  • and rainfall;

Readings for any further weather parameters (solar or UV intensity, soil temperature and moisture etc) will depend on which of the optional VP2 supplementary transmitters may also specified for the system.

So, in a basic configuration, Connect will be receiving data from a single Vue/VP2 transmitter (typically an ISS, but in principle even a single 6372 temperature transmitter will work). But further sensors and transmitters can be added as required, provided the same rules as for a standard VP2 station for mixing transmitter types are followed (e.g. only one ISS main sensor unit allowed per Connect unit).

Connect uploads the data automatically at regular intervals to the central server at, from where the data may be downloaded to a local PC or viewed as a webpage in any standard browser or on most smartphones.

Connect in more detail

The Vantage Connect unit is therefore an extension to the main Davis Vantage family of Vantage Pro 2 and Vue weather stations and works with existing Vantage sensor transmitters, but replaces the console, logger and data link parts of a conventional Davis system.

The Connect unit thus combines four components of a remote weather VP2 monitoring system into a single assembly:

  • Console/receiver, replacing the standard VP2 or Vue consoles or Envoy unit;
  • Data logger;
  • Cellular modem;
  • Self-contained, solar-powered power supply (with rechargeable battery for overnight and low-light operation);

So, for a complete remote weather monitoring system, all that’s needed – in addition to the Connect unit itself – is a standard VP2 wireless sensor assembly (ISS) such as the 6322OV or 6327OV Plus ISS units (or even a basic 6357 Vue ISS unit), together with any extra wireless sensors that the application may call for. The Connect unit removes the need for any type of conventional VP2 console or weatherproof shelter to be present and is fully compatible with all Vantage family wireless transmitters and repeaters.

Dimensions of the Connect unit are approx 35 x 25 x 11cm (14 x 10 x 4″) and attaches to a pole via U-bolts top and bottom. The unit can also be mounted to any flat surface, but pole-mounting will often be preferred because it will usually achieve greater height and hence better mobile reception. The field image at the top of this page shows relative size and typical configuration more clearly. The unit has a significant weight (4kg) due to the lead-acid battery onboard).

Connect is powered by a 5W solar panel charging the 6v/12Ah battery via a high-efficiency MPPT regulator. Early experience suggests that this power supply provides more than adequate power reserves to carry the unit through the dull UK winter months, although in more demanding locations such as Northern Scotland it may be desirable to avoid the 5-minute data plan (which consumes most power) or also to specify, for example, the  6616 Supplementary Solar Panel.

To summarise the data handling in a little more detail: The data logger built into the Vantage Connect receives and stores all the data that a standard VP2 logger can log . The Connect then uploads the stored data automatically at regular intervals of 5, 15 or 60 minutes to a secure page on the website. You also have the option to download a comprehensive data record to your own PC for detailed analysis, archiving and reporting. (NB Please note that uploads can only be made to the server – the uploads cannot be redirected to any other server.)

The Vantage Connect also allows alarm conditions to be programmed. If a particular combination of weather conditions occurs, an alarm signal will be sent immediately to the server from where the user can be alerted by email or, at modest extra cost, SMS text (by setting up a link to a suitable email-to-SMS gateway service). Other features of a account such as automatic uploads to online networks such as Weather Underground are also available.

Configuration of the Connect unit (eg transmitter channel settings, alarm settings, display units, calibration parameters etc) can all be set remotely via the web interface pages of the Connect account at All Connect configuration functions are therefore managed remotely.
