bOS Values for 1byte are different in KNX

Jürgen Jürgenson 6 years ago in Devices / KNX updated 6 years ago 2

Hey,

Our client wanted to change ventilation speeds from the thermostat. Ventilation runs on Modbus everything else is on KNX bus.

This may be a really stupid question but... i found that when i put a value for 1byte in bOS 1 then KNX sees it as 3 and value 2 as 5. But in bOS it shows the correct values. Ventilation has 3 speeds that we control (0 is for away, 1 is home, 2 is guests) I made some screenshots. 
In bOS

Shows as correct value in bOS

But in KNX sees it as 3 and value 2 as 5 in knx

Is this normal or am i missing something? 

I got it working though by changing the values in the Thermostat to 3 and 5, there is no problem with value 0 :) . So now every thermostat shows the correct status and from every thermostat they can change the ventilation speeds. But I find it weird that it changes the values like that.

Best regards.

buttons & lighting "night mode"

Dave De Busschere 7 years ago in Devices / KNX updated 6 years ago 5

Hello,

I'd like to use the night mode in the buttons (light up and night).

and at the same time i wan't to have the lighting in the bedroom area (toilet, bedrooms, halway,..) to work at ca. 40%.

All lights are DALI dimmable. 

I made a group 3/3/4 night buttons where i put the 4(general) LED - brightness mode in.

What do i have to do in bosconfig for the nightmode buttons and what for the lights to go max. 40%?


Thanks,

error connecting to KNX device

Francois Lesueur 7 years ago in Devices / KNX updated by Dieter Kraewinkels 6 years ago 27

Hello,


I'm getting many "error connecting to KNX device".


On my first system (Grinder), this is happening from times to times, for a very short period of time (<1 min). 

This is not impacting the good operation of the system, except if this happening when bOS needs to issue a KNX command, but that's very rare, and then I noticed an impact only once.

I thought that maybe this was linked to my IP network that needed some troubleshooting.


But I've got another system, a KNX Jigsaw, for which the KNX error connecting to device is occurring every 2 minutes ! The KNX interface being incorporated into the Jigsaw, this can't be an issue with my environment. 

I'm not using KNX on this Jigsaw, so I just disables the KNX interface, and problem was fixed for me. 


Still I would like to understand how to fix these "error connecting to device" incidents. 


I'm also getting them from times to times for all IP-connected devices: global Caché, Philips Hue, Denon amplifier, etc... 


Thanks,

François
