/* MyMQTT Gateway 0.1b
Created by Daniel Wiegert <daniel.wiegert@gmail.com>
Based on Mysensors Ethernet Gateway by Henrik Ekblad <henrik.ekblad@gmail.com>
Requires MySensors lib 1.4b
http://www.mysensors.org
* Don't forget to look at the definitions in MyMQTT.h!
* Don't forget to configure Radio pins, IP and MAC-address!
* Address-layout is : [MQTT_BROKER_PREFIX]/[NodeID]/[SensorID]/Light
NodeID and SensorID is number (0-255).
Last segment is translation of the sensor type, look inside MyMQTT.cpp for
the definitions. User can change this to their needs.
Example openhab setup: http://www.openhab.org/
* openhab.cfg
---
mqtt:mysensor.url=tcp://192.168.0.234:1883
mqtt:mysensor.clientId=MQTT
---
* items/test.items
---
Group test
Number Temp_test "Temp [%.1f °C]" (test) {mqtt="<[mysensor:MyMQTT/20/#/Temperature:state:default]"}
Number Hum_test "Hum [%.1f %%]" (test) {mqtt="<[mysensor:MyMQTT/20/#/Humidity:state:default]"}
Number test_test "test [%s]" (test) {mqtt="<[mysensor:MyMQTT/20/3/#:state:default]"}
Switch sw1 "sw 1" (test) {<[mysensor:MyMQTT/21/1/Light:command:MAP(1.map)]"}
--- (Note; # = Wildcard character)
* sitemap/test.site
---
sitemap demo label="Menu"
Frame label="Openhab" {
Group item=test label="Test group"
}
---
* transform/1.map
---
1=ON
0=OFF
---
* Features:
- Supports automatic nodeID delegation
- Recieve sketchname and version Example: (openhab item)
String sketch20 "Node 20 Sketch name [%s]" (sketch,name,a) {mqtt="<[mysensor:MyMQTT/20/255/Sketch_name:state:default]"}
String sketch21 "Node 21 Sketch name [%s]" (sketch,name,a) {mqtt="<[mysensor:MyMQTT/21/255/Sketch_name:state:default]"}
[...]
* Todo:
- DOCUMENTATION...
- Special commands
Read and set EEPROM Values
Send Reboot, And reboot gateway itself.
