alexa not responding

Adi Shamir 1 year ago in Devices / KNX updated by Jürgen Jürgenson 6 months ago 16

Hello, I have all my KNX devices at home connected via BOS to Alexa - about 70 devices. All worked well, until suddenly Alexa stopped responding to all devices. i.e. - When I ask Alexa to 'turn on' a device, it says that the device is not responding - this is the same situation with all my KNX devices. To clarify, BOS works well from the app and also Alexa works well with other devices not connected via BOS. Any idea?

Are there any fast way to input status adresses when importing from KNX or is typing them in manually the way to go?

Room Thermostat KNX

@Nea Smyrni 2 months ago in Devices / KNX updated by Fabien Fuster 1 month ago 11

Hi to everyone I am trying to make a room KNX thermostat visualization by using bOS. What I need to do is to control a fancoil and an underfloor heating /cooling valve as main system . First I want to have On/Off for the system. Second I need to turn the fan coil fans speed to automatic , and to manual mode if needed. Also If the the fan mode is to manual I want to control this in steps like fan 1 , fan 2, and fan 3 and back again to 0. Another thing I want to see every time the room's temperature. Also I want of course to change the setpoint of the room thermostat. From the visualization program I want to have Heating / Cooling to be changed (I noticed when I am changing the status from ETS from Cooling to heating mode the icon is changing the opposite I don't know why is this happening). I forgot to mentioned that when the setpoint is changing I want also the setpointing temperature changes to appear of course in the visualization program. Also I want o have the valve of the underfloor heating/cooling to be turn On or Off when the appropriate temperature is set (and see the status of course ) . Last but not least is the 3 modes I Comfort , Away , Night that I want to insert it to the visualization program.  I tried to insert at the beginning  the Room's temperature and it doesn't show me the correct number. Should I have to change it to another format or sometthing?


Lighting Scene and time schedules

@Nea Smyrni 2 months ago in Devices / KNX updated by Fabien Fuster 2 months ago 6

Hi to everyone. I have to find a solution as soon as possible regarding a new project  with KNX system. We have an analog (not a KNX ) LUX meter from ABB which sends an On command when the external lighting is low . This command is going  to a digital input and this input sends the command to the KNX ouput device to turn On the lights. What we need is that when the digital input send the command we want to enable a scene /time schedule that all the lights are going to be dimmed for example to 70% , from 8pm to 10pm, after 10pm the lighting must go automatically to 40% from 10pm to 12pm. From 12 am and when the digital input send the command to turn Off the lights the lights must be dimmed to 20%. Any ideas on how I can create this kind of scene/ time schedule? Thank you in advance.

Jigsaw KNX

matej bregar 5 months ago in Devices / KNX updated 5 months ago 2

Hi there, I have Jigsaw installed and connected to KNX bus.

But since then whenever I try to set new KNX devices in ETS, I get error message "More than one device is in programming mode". I have to shutdown Jigsaw to assign an address to new KNX device.

Do I have to do some additional setup steps to connect Jigsaw to KNX, I guess it has to be something with Jigsaw being in programming mode?

Thank you for your help, Regards


Dimmer relative, down button can't be used

Vinatoru Mircea 5 months ago in Devices / KNX updated 5 months ago 1


I added a dimmer switch (3.007 Control Dimming) in my project, and I can't use on the down button control.

After I edit the button it switch to the up control. Even in the dimmer template is the same issue.

Is this a bug ? It can be fixed ?

2 weeks ago I have done my setup with Alexa. All works fine.

Today the Light turned on without any command.

I'm wondering if there are any security breaches with the Alexa echo.

Any hints?
