Installation Guide

[hartmood]

Can you please give more information on how to install for the "not so savvy"?

Have you managed to build the JAR?

Change the properties file "UVOC.properties" to your environment and place it next to the jar.

Then launch the JAR from a command line like "java -jar uVOC.jar"

[hartmood]

Unfortunately I am more a user / adaptor. So building a jar file is the first challenge. At least I have managed to have this running. https://www.hackster.io/damancuso/indoor-air-quality-monitor-b181e9 And Zigbee2mqtt / openHAB works great here. So Basics are done.

A very basic Installation guideline would help a lot to use your code.

[dl2sba]

Building is done via MAVEN.

I've added the V1.5 JARs to the bin directory.

[hartmood]

Thanks a lot - I finally managed to compile a jar with dependencies with maven ("maven package") - how can I add the ttyACM0: on my raspberry to the Com Port?

[dl2sba]

Not tested, but I assume you should change this line in the properties file to:

UVOC.ComPort=/dev/ttyACM0

[hartmood]

UVOC.ComPort=ttyACM0 works. You can use AUTO to detect the port.

Nevertheless I struggle to have it posted to openHAB as I am not really familiar with the mqtt syntax.

Thing topic AirQuality "AirQuality" @ "Dachgeschoss" { Channels: Type number : temperature "temperature" [ stateTopic = "dl2sba.de/sensorData/%d/%d/AirQuality/MQTT.sensor.temp.id=0" ] } Thing topic EG_WZ_THS "Wohnzimmer THS" @ "Wohnzimmer" { Channels: Type number : temperature "temperature" [ stateTopic = "zigbee2mqtt/EG_WZ_THS/temperature" ] Type number : humidity "humidity" [ stateTopic = "zigbee2mqtt/EG_WZ_THS/humidity" ] Type number : pressure "pressure" [ stateTopic = "zigbee2mqtt/EG_WZ_THS/pressure" ] Type number : voltage "voltage" [ stateTopic = "zigbee2mqtt/EG_WZ_THS/voltage" ] Type number : battery "battery" [ stateTopic = "zigbee2mqtt/EG_WZ_THS/battery" ] Type number : linkquality "linkquality" [ stateTopic = "zigbee2mqtt/EG_WZ_THS/linkquality" ] } I have added a working zigbee2mqtt example - Dietmar, any idea? Another big thank you by the way.

[dl2sba]

AUTO - only a good idea if you have only one serial port ;-)

Sri, I do not know the openHAB syntax.

You can write you own "Publisher" use the sample class "SensorDataPublisher" as a template.

[hartmood]

True, at least it helped to find the right port. And it is starting so far.

i would expect to see some traffic with subscribing to /dl2sba.de/sensorData/9800/ or dl2sba.de/sensorData/9800/

But I receive no traffic.

[dl2sba]

You must subscribe to a specific sensor topic, i.e. "/dl2sba.de/sensorData/9800/0" for the temperature or to "/dl2sba.de/sensorData/9800/+" for all topics below 9800 ...

[hartmood]

Thanks. It works now. The only thing I wonder why there is a delta between the IAQ I receive with your code compared to the value I have in my dashboard. IAQ: dl2sba: 58.5 IAQ dashbaord. 35

AAAAAAAAAA 11:31:05.694 [main] DEBUG UVOCReader processLine - response [{"temperature": 19.53, "pressure": 1023.12, "humidity": 40.31, "g

All other values seem to be correct.

I use this python script to write to influxdb and use grafana for the dashboard. https://www.hackster.io/damancuso/indoor-air-quality-monitor-b181e9

[hartmood]

Sorry, my fault. Port has changed.
