# Meteostick Binding
|
|
|
|
This is the binding for the [Meteostick](https://www.smartbedded.com/wiki/index.php/Meteostick) weather receiver dongle.
|
|
This is an RF receiver that can receive data directly from Davis weather devices (and others).
|
|
|
|
## Supported Things
|
|
|
|
This binding support 2 different things types
|
|
|
|
| Thing | Type | Description |
|
|
|----------------------|--------|-----------------------------------|
|
|
| meteostick_bridge | Bridge | This is the Meteostick USB stick |
|
|
| meteostick_davis_iss | Thing | This is the Davis Vue ISS |
|
|
|
|
## Binding Configuration
|
|
|
|
The Meteostick things need to be manually added - there is no discovery in the Meteostick binding.
|
|
|
|
First add and configure the Meteostick bridge - the port and frequency band for your region need to be set.
|
|
Next add the sensor and configure the channel number.
|
|
|
|

#### Rainfall
|
|
|
|
There are four channels associated with rainfall.
|
|
The raw counter from the tipping bucket is provided, the rainfall in the last 60 minutes is updated on each received rainfall and provides the past 60 minutes of rainfall.
|
|
The rainfall in the previous hour is the rainfall for each hour of the day and is updated on the hour.
|
|
The accumulated rainfall for today provides the amount of rain for the current date and will reset to 0 at timezone's midnight.

## Full Example
|
|
|
|
This example uploads weather data to for your personal weather station at Weather Underground every two minutes.
|
|
|
|
Steps:
|
|
|
|
1. Install the [MeteoStick](https://www.smartbedded.com/wiki/index.php/Meteostick) binding for use with your [Davis Vantage Vue Integrated Sensor Suite (ISS)](https://www.davisnet.com/solution/vantage-vue/).
|
|
1. [Register](https://www.wunderground.com/personal-weather-station/signup.asp) your personal weather station with Weather Underground and make note of the station ID and password issued.
|
|
1. Add the following files to your openHAB configuration:
|
|
|
|
### things/meteostick.things
|
|
|
|
Things can be defined in the .things file as follows:
|
|
|
|
```java
|
|
meteostick:meteostick_bridge:receiver [ port="/dev/tty.usbserial-AI02XA60", mode=1 ]
|
|
meteostick:meteostick_davis_iss:iss (meteostick:meteostick_bridge:receiver) [ channel=1, spoon=0.2, deltaWindDirection=0 ]
|
|
```
|
|
|
|
Note the configuration options for `port`, `mode`, `channel`, `deltaWindDirection` and `spoon` above and adjust as needed for your specific hardware.
|
|
|
|
