For the shutters I’ve defined groups for different rooms and floors. To trigger up or down for the shutters I just give the command to the group. In the openhab 1.8/ 1.9 it worked as expected. After upgrading to openhab 2.4 some of the shutters randomly are not reacting. If I give the trigger comm…

I use the “physical” groups within KNX using group telegrams. Now it works, all items are triggered. The big drawback of this solution is, that the physical actors are accepting only a limited number of telegrams they’re reacting. That means, that you cannot involve one physical knx items in a lot…

You might get what you want by making use of the MQTT group topic instead of the group of openHAB items. By using the MQTT group topic only one mqtt command is sent and all connected devices react

Have a look in your events.log, to make sure the command is propagated to the Items that you expect. Then you’ll know it is not a Group issue, but rate of individual commands.

The log is mentioning following: 2020-04-27 19:57:34.736 [ome.event.ItemCommandEvent] - Item 'gShutterEGWork' received command DOWN 2020-04-27 19:57:34.766 [ome.event.ItemCommandEvent] - Item 'Shutter_GF_Work_J_1' received command DOWN 2020-04-27 19:57:34.797 [ome.event.ItemCommandEvent] - Item '…

I’m sorry, but I misconcepted that you would get using MQTT. @rossko57 Thanks for stepping in. Using grouped items in openHAB would enable to use a single openHAB command to trigger grouped items to do something. The downside is, each grouped device would need it’s own command to start that someth…

what is really annoying is, that it worked till the upgrade to openhab 24. I used 1.8/ 1.9 on a mini pc connected windows via WLAN IP interface from Weinzierl. Now I’m using raspberry connectd via USB, open 2.4 and a lot of things were not easily transferred, because of working differently… At th…

There’ll be a lot of timing differences between OH1 on a PC and OH2 on a Pi.

Apparently. Due to the fact that a lot of applications will be on a raspberry it’s a pitty that it’s not working as it should…

Based on observations I made a long time ago, so I might be misremembering things, what is probably happening is that the 1.x binding was much less efficient in how it published messages meaning the messages were far enough apart that the KNX could process them all. The new binding is more efficient…

And there is a bugfix already for knx… see [image] Sending off command to group of lights results in some lights staying on, with missing "changed to" log message Items & Sitemaps I have now been in contact with the maintainer of Calimero the library that the K…

Not all group members triggered are reacting

And there is a bugfix already for knx… see

So it seems it was an calimero bug, or at least calimero now takes care of the timing.

knx2 should be updated…
