Ruuvi gateway node

The node uses the poll mode to retrieve the values from the Ruuvi Gateway and gets triggered when receiving input.

Inputs

• payload (string|number|json) : the trigger to poll the Ruuvi gateway

The msg.topic is filled with the MAC address of the queried gateway.

Outputs

• payload (json) : the answer from the Ruuvi gateway

A typical answer contains a few top level fields:

• timestamp : the timestamp of the retrieval
• tags : an object, containing all of the tags that are within reach of the gateway
• gw_mac : the MAC address of the queried gateway

The tags contain an object for each found Ruuvi sensor, identified by its id. Typical fields that reside within this object are:

• rssi : the signal strenght
• timestamp : timestamp of the last received sensor reading
• data : raw field containing the data of the sensor
• dataFormat : identifier for the data format
• temperature : the temperature in degrees Celsius
• humidity : the humidity in percentage
• pressure : if available, the pressure. Seems to return null
• axelX ,axelY and axelZ - movement information
• movementCounter - how often the sensor was moved
• voltage - the battery voltage
• txPower - the transmit txPower
• measurementSequenceNumber - a sequence number
• id - the identification id for the sensor

Configuration

• name (string) : the name for the node
• gateway (ruuvi config) : the configured Ruuvi gateway
• store in global context (boolean) : whether or not to store the answer in the global context
• verbose (boolean) : show the used curl command in the debug tab

Configure the gateway to enable poll mode. Then copy and paste the token into the configuration of a new Ruuvi gateway.

Also fill out the hostname or ip address for the Ruuvi gateway. The easiest way is to enter ruuvigatewayXXXX.local, where the XXXX match the code, which is printed on the backside of the Ruuvi gateway.
