Jeelink MQTT

This program exposes Jeelink data via MQTT. It connects to a given serial port and publishes data to a given MQTT topic.

The program is written in Java. You can run it on almost any device which can run Java.

Config file

Create a jeelink.properties file with the following content. The file must be placed beside the *.jar file.

mqttServer=tcp://broker.my.lan   #address of your MQTT server
logLevel=INFO                    #log level
topic=home/temperatures          #root topic
sketchName=LACR                  #LACR or EC3K
serialPortName=/dev/usb-lacr     #port name of your jeelink

Building and running

To build run the following commands:

mvn clean install
java -jar target/jeelink-mqtt-0.1.0-SNAPSHOT-jar-with-dependencies.jar

Alternatively you can download a release.

Supported sketches

Lacrosse

Use LACR as sketchName. The following data is published for each sensor:

home/temperatures/18/temperature 22.2
home/temperatures/18/humidity 48
home/temperatures/18/batterylow false

Energy Count 3000

Use EC3K as sketchName. The following data is published for each sensor:

home/ec3k/14E7/currentpower 31.0
home/ec3k/14E7/energy 199774
home/ec3k/14E7/timeon 24106151
home/ec3k/14E7/timetotal 24106151
home/ec3k/14E7/maxpower 51.6

Integration into Openhab

Sample for Lacrosse

Number temp_room1   "room1 temp [%.1f �C]" <temperature>  { mqtt="<[mosquitto:home/temperatures/63/temperature:state:default]" }
Number hum_room1   "room1 hum [%1d %%]" <humidity>  { mqtt="<[mosquitto:home/temperatures/63/humidity:state:default]" }
Switch bat_room1 "room1 battery low" {mqtt="<[mosquitto:home/temperatures/63/humidity/batterylow:state:MAP(battery.map)]"}

You need a battery.map file:

true=ON
false=OFF
NULL=OFF

Sample for EC3K

Number ec3k1Power "ec3k 1 power" { mqtt="<[mosquitto:home/ec3k/0E3D/currentpower:state:default]" }
Number ec3k1Max "ec3k 1 max" { mqtt="<[mosquitto:home/ec3k/0E3D/maxpower:state:default]" }
Number ec3k1EnergyTotal "ec3k 1 total" { mqtt="<[mosquitto:home/ec3k/0E3D/energy:state:default]" }

TX22 (wind,rain,temp,hum)...

Hi, thanks for your effort and development done...

Is there a chance that you are also trying to support TX22....its already implemented in the LaCrosse-LaCrosseITPlusReader code (fhem).

Packets look like this....

Message Format:
SSSS.DDDD DDAE.LQQQ TTTT.VVVV VVVV.VVVV ... CCCC.CCCC
Data - organized in nibbles - are structured as follows (example with blanks added for clarity):
a 5a 5 0 628 1 033 2 000 3 e00 4 000 bd

data always starts with "a"
from next 1.5 nibbles (here 5a) the 6 msb are identifier of transmitter,
bit 1 indicates acquisition/synchronizing phase
bit 0 will be 1 in case of error
next bit is the low battery flag
next three bits (here 5) is count of quartets transmitted
up to 5 quartets of data follow
each quartet starts with a type indicator (here 0,1,2,3,4)
0: temperature: 3 nibbles bcd coded tenth of °C plus 400 (here 628-400 = 22.8°C)
1: humidity: 3 nibbles bcd coded (here 33 %rH)
2: rain: 3 nibbles, counter of contact closures
3: wind: first nibble direction of wind vane (multiply by 22.5 to obtain degrees, here 0xe*22.5 = 315 degrees)
next two nibbles wind speed in m/s
4: gust: speed in m/s
next two bytes (here bd) are crc.
During acquisition/synchronizing phase (abt. 5 hours) all 5 quartets are sent, see example above. Thereafter
data strings contain only a few ( 1 up to 3) quartets, so data strings are not always of equal length.
