Tasmota KNX functions

[WoutervanZijl]

PROBLEM DESCRIPTION

A clear and concise description of what the problem is. Currently i have a few device with Tasmota KNX but i canot find any option to choose like relay or button or anything, The only option i have is to select a output in the configuration menu of knx. My modules are Sonoff 4 ch pro and 3 sonoff basics all with tasmota knx 9.1. I have searched online but only see picture on the tasmota knx wiki where there is a button selected or humidity and other option. Am i doing something wrong or is there more info hidden or coming.

What i would like if possible is to program my sonoff 4ch pro so that my rf buttons are seperate from the sonoff device to start scene or indeed switch a relay so that its more programmeble to amazing idees:)

I realy like knx and if I could help in any way or test ( not a programmer but a enthousiast for sure)

Hope this the correct way of communicating because i dit tryed the chat but no luck there.

Wel I wil try.

I got 1 ligt up en running with tasmota. For testing I have put group adress 2/1/2 to listen to. But now I wanted to make it permanent en removed 2/1/2 from the kist to toggle and added 3 different knx group adress to listen to but for some reason it is stil listening to 2/1/2 even its not in the list anymore. Somehow the data is stil on tasmota. Also ive added 2/1/7 for the new action off but this doesn not get to this light but it does to others so the knx signal is there.

ok, please,

• go to the console and type weblog 4
• then go to the KNX menu, and post here the screenshot of it.
• then on the KNX menu click on save
• Go again to the console and post the console output.

Thanks.

@ascillato , thank you a lot for all the help in this thread, I went through it but please allow me to ask a question differently just to be sure I got it the correct way .. I currently have KNX devices that are wired TP to the bus .. and I intend to install a relay that runs on tasmota along with a few push buttons

so what needs to be done is to add an IP router to connect my existing KNX devices to IP

after that configure tasmota now when I need another none tasmota device lets say a KNX wall switch to control the

Tasmota relay do I add the tasmota as a dummy device on ETS ? and that would work ?

this issue is probably not the best place to discuss it but i'll answer anyway. (ascillato is busy enough)

first you need an KNX/IP router to connect your KNX-TP (twisted pair) network to IP. Make sure KNX routed traffic on IP Multicast 224.0.23.12 UDP port 3671 works between your tasmota devices and the KNX/IP router. That is the most problematic part for many poeple, some routers, switches and wireless access points do strange things with multicast or block it.

If IP works then you have pretty much two ways to make communication work for KNX.

1) configure you KNX/IP router to pass ALL datagrams. This is kind of dangerous (IP could overwhelm the 9k6 TP network) but in a private home probably ok. NO dummy is required in ETS but it make your life easier to use any anyway. 2) your KNX/IP router filters and only necessary datagrams for forwarded between IP and TP. in this case you NEED the dummy because ETS "programs" the router filter tables.

@MGKQB thank you

Hi,

Thanks for answering. That part of the setup is not fully explained in the Tasmota KNX docs ( https://tasmota.github.io/docs/KNX/ ). Please, if you could add more info there, that will help people a lot.

Thanks, very appreciated !
