I am having an KNX power supply system with some diagnostic functions from MDT and I want to integrate some status information from that system to my Home-Assistant UI.
Is there an build in way to query group adresses like as you do with the knx.send service?
My problem is that the information I want to access is not pro-actively shared on the bus and I have to actively query it but I cannot find a proper way to do so.
You mean that you want to see the status after a restart of the HA server?
So I have my alarm armed and see it on a 6 way input module of knz (mdt) .
After a reboot of the system I doesn’t see him anymore until I switch the alarm on and off.
Did you check if the flag R is enable in the status of the actuators?
When the HA ask for the status, if the flag R is not enable, the actuator does not send the status.
Hi Markus,
at the moment I’m building my house, with KNX. I was just thinking about some usecases for HA and one of them could be to control the brightness of a light by reading an illuminance sensor. There I think I will face the same problem: The sensor can send its value regularly, but minimum time is 30s - If I switch on the light, I want to get the sensor value as fast as possible, with 30s delay I cannot control anything. That’s why I would like to actively read the value from the sensor after turning on the light.
And I think there are devices that do not even have the option of sending regularly. Therefore such a read feature would be great.
@der-optimist all of my knx devices send values to the bus if they change internally (eg. light is dimmed up - some telegrams are sent). Additionally I can configure them to send periodically, but this is hardly ever necessary.
