/* 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

|
|
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)]"}

|
|
|
|
* 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.
|
|
...

|
Sketch uses 23,666 bytes (77%) of program storage space. Maximum is 30,720 bytes.
|
|
Global variables use 766 bytes (37%) of dynamic memory, leaving 1,282 bytes for local variables. Maximum is 2,048 bytes.
