This is a fork of MonitorKNXRF where the integration with OpenHab has been removed. Instead the sensor data will be published to a MQTT Broker

This program is developed to be used on Raspberry Pi 3 together with a CC1101 radiomodule.

The program will listen to interrupts generated from the CC1101. When an interrupt is recieved the data will be stored to a variable length buffer of class SensorKNXRF. Every 15th second the program will send the data to a configured MQTT Broker.

Note: GDO0 is not used in the program. which GDO for interrupts to use is specifed in the configuration of the chip, see cc1101.cpp (look for IOCFG[0..2] and the data sheet for the CC1101.

Compile the program by running make:

openhabian@hab:~/MonitorKNXRF$ make

Run the program with debug level 2:

./knx-monitor 2

Change set temperature on any of your thermostats, and wait a minimum 15 seconds. Press Ctrl+C to stop the program. Then check the log:

grep -in monitorknxrf /var/log/syslog
...
24447:Jan  2 12:09:00 hab knx-monitor: MonitorKNXRF is requesting data from Openhab.
24448:Jan  2 12:09:00 hab knx-monitor: MonitorKNXRF got data from sensor 007402363C12 reading 2232 and 1950.
24451:Jan  2 12:09:00 hab knx-monitor: MonitorKNXRF: marcstate: 0x01

In this case the actual temperature is 22.32 C and the set temperature is 19.5 C.

To make the program running as a system service you need to copy the the systemd files as this:

sudo cp knx-monitor /usr/bin/.
sudo cp knx-monitor.service /etc/systemd/system/.

Manual start / stop the service

sudo systemctl start knx-monitor.service
sudo systemctl stop knx-monitor.service
sudo systemctl status knx-monitor.service

Have the program started on system boot

sudo systemctl enable knx-monitor.service

The docker is still in progress. Goal is to have everything build and running in a docker container

Build docker image

docker build -t knx .

Test docker image

docker run -it --rm knx bash
