Bridge between RFLink Gateway and MQTT broker.
Forwarding messages received on TTY port from RFLink Gateway Arduino board to MQTT broker in both directions.
Every message received from RFLinkGateway is split into single parameters
and published to different MQTT topics.
Example:
Message:
20;83;Oregon Rain2;ID=2a19;RAIN=002a;RAINTOT=0054;BAT=OK;
is translated to following topics:
/data/RFLINK/Oregon Rain2/2a19/R/RAIN 002a
/data/RFLINK/Oregon Rain2/2a19/R/RAINTOT 0054
/data/RFLINK/Oregon Rain2/2a19/R/BAT OK
Every message received on particular MQTT topic is translated to RFLink Gateway and sent to 433 MHz.
Whole configuration is located in config.json file.
{
"mqtt_host": "your.mqtt.host",
"mqtt_port": 1883,
"mqtt_prefix": "/data/RFLINK",
"rflink_tty_device": "/dev/ttyUSB0",
"rflink_direct_output_params": ["BAT", "CMD", "SET_LEVEL", "SWITCH", "HUM", "CHIME", "PIR", "SMOKEALERT"]
}| config param | meaning |
|---|---|
| mqtt_host | MQTT broker host |
| mqtt_port | MQTT broker port |
| mqtt_prefix | prefix for publish and subscribe topic |
| rflink_tty_device | Arduino tty device |
| rflink_ignored_devices | Parameters transferred to MQTT without any processing |
Application pushes informations to MQTT broker in following format: [mqtt_prefix]/[device_type]/[device_id]/R/[parameter]
/data/RFLINK/TriState/8556a8/W/1 OFF
Every change should be published to topic: [mqtt_prefix]/[device_type]/[device_id]/W/[switch_ID]
/data/RFLINK/TriState/8556a8/W/1 ON
