connect an antenna that is not directly mounted to the connector but has some cable to bring the antenna further away from the RF noise the Meteobridge PRO is inevitable producing and by that giving the RF signals more head room by reducing the noise floor.replace small antenna by a larger one that better fits to the wave length of your sensors signals.What you can do in principle is going three ways: Meteobridge PRO offers a standard SMA plug, where any antenna suitable for the RF band your Davis sensors operate in (915 MHz for US, 868 MHz for EU) will fit, as long as it has a male SMA plug. RF antenna on the back panel of the Meteobridge PRO can be unmounted and replaced by a larger and more capable model. No one can tell you what best position will be in your location, but you are highly invited to check out yourself. If you like watching the numbers change, this 30 second movie might be of interest to you (moving black bars on display are just camera artifacts). By the way, the display is white but my camera makes it look blue sometimes. Signal strength in the mid -50db is much better and will allow the sensors to go further away without having the connection dropped. By moving the Meteobridge less than a meter away to a higher position on a shelf, reception situation improves significantly. When it reaches the -90 db reception will get tough. Values around -70db are not great, but still no problem to receive. Picture on the left shows reception when Meteobridge PRO is directly sitting on my desk with a lamp, some metal enclosures and the metal corpus underneath my desk in direct neighborhood. Having done so the Meteobridge PRO display will show data like this: For the moment you don't need to know the details -) If you want to understand how this works, please have a look at page PRO_Display. Don't be confused by the message text that is automatically inserted. Settings for this service should look like shown on the right picture. Then specify "every 5 seconds" as interval and select "Meteostick RF Analysis" from the list of pre-defined standard messages. Press "Add Service Event" and a new event will be added to the list of already defined events. To do so, define a new service of type "Display" and select "Periodical" as it's event type. As you might want to move the Meteobridge PRO and test for various locations, having an Ethernet cable hanging around will be annoying.ĭefine a display service on "Services" tab that shows RF data from the outdoor sensors on the integrated display and updates the display every 5 seconds. Configure your Meteobridge PRO to connect via WiFi with your network.Turn the Meteobridge PRO into an RF strength meter and find a good place to restīefore you start experimenting how to improve RF reach we recommend to run through the following steps: This section of the tutorial explains what you can do if you need improved RF sensitivity. However, if your sensors are far away some tweaking of RF reception might be necessary. The antenna shipped with Meteobridge PRO is quite good in RF operation and picks up about 5 db more signal strength than the wire antenna of Meteostick does. To keep RF noise away from the reading Davis sensor data, we designed an external antenna. Compared to a Davis console where only very little computing stuff is happening, we have a high density of sensors, computing modules, Ethernet circuitry and even a WiFi module all together in a very compact housing. Meteobridge PRO (red cap model) has a RF receiver included to directly pick-up data from Davis outdoor sensors. 1.1 Turn the Meteobridge PRO into an RF strength meter and find a good place to rest.
