[SOLVED] Control an entire group with a single proxy item

[Z0l (Zoltan Orosz)]

• Platform information:
  • Hardware: Raspberry 3
  • OS:Openhabian
  • Java Runtime Environment: Zulu
  • openHAB version: 2.4
• Issue of the topic: I would like to control 5 rollershutters with a single proxy item; when the proxy item change status, only a single shutter moves. What is the correct way to address this? List all 5 after the sendCommand instruction so they move together? According to the logs all of them receive the command but only one of them moves.

Previously I was able to get this done using a Group entry in the sitemap with the mapping (with the 1.13 Souliss binding), but with the latest version of the Souliss binding, I no longer define the items of the binding, instead I add the gateway and the things get auto-discovered and then I link them to my items. With the latest binding, the same method of adding a Group entry to the sitemap with all the items produces the same behavior (only 1 shutter moves, not all of them). Unfortunately version 1.13 of the Souliss binding (which you can install from PaperUI) keeps one CPU spinning on 100% so I’d prefer to keep the newer one and figure out how to move all 5 together.

• Items configuration related to the issue

Channels are defined via PaperUI, but they are all Souliss entries which work fine when commands are sent to an individual entry.

Rollershutter GF_LivingRoom_Shutter1 “Roller Shutter” (GF_LivingRoom, gShutter) [“Rollershutter”] {channel=""}
Rollershutter GF_LivingRoom_Shutter2 “Roller Shutter” (GF_LivingRoom, gShutter) [“Rollershutter”] {channel=""}
Rollershutter GF_LivingRoom_Shutter3 “Roller Shutter” (GF_LivingRoom, gShutter) [“Rollershutter”] {channel=""}
Rollershutter GF_Bedroom_Shutter1 “Roller Shutter” (GF_Bedroom, gShutter) [“Rollershutter”] {channel=""}
Rollershutter GF_Bedroom_Shutter2 “Roller Shutter” (GF_Bedroom, gShutter) [“Rollershutter”] {channel=""}

Perhaps this would work with a delay between each command sent.
That does mean you’d need a rule based solution, not using a group’s inbuilt command passing.
You can iterate over a group’s members in a rule.
Example

Trigger Group Item over KNX

Given these items: Rollershutter knxAllShutters {knx="..."} // or a Switch item, if you only want UP/DOWN Group:Rollershutter gShutters Rollershutter rShutter_01 (gShutters) {knx="..."} Rollershutter rShutter_02 (gShutters) {knx="..."} Rollershutter rShutter_03 (gShutters) {knx="..."} Rollershutter rShutter_04 (gShutters) {knx="..."} Rollershutter rShutter_05 (gShutters) {knx="..."} Rollershutter rShutter_06 (gShutters) {knx="..."} ... The rule would be like this: rule "drive all shutters" w…

Thanks, I’ll experiment with it and let you know. Gave it a quick try, but it only moved 2 out of the 5 (even though I have not added any delays, so I’ll try that and see if it helps).

@Z0l

Previously I was able to get this done using a Group … but with the latest version of the Souliss binding, I no longer define the items of the binding, instead I add the gateway …

Maybe the underlying issue is that the gateway isn’t queuing commands nicely.

[Z0l (Zoltan Orosz)]

Yes, turned out if I add a 0,2 sec delay, it works flawlessly. Now there’s just one last thing, is there a way to sort the group so the commands gets executed in the same order all the time? Right now, when I close the shutters, they close in a different order than when I open them and I have to open them all completely to align them Any ideas for that? I saw there’s a function for sorting them (gGShutter.members.sortby) but not sure how to add it to the current code. Btw this is the working code:

rule "GF proxy roller"
when
        Item ProxyRollerGF received command
then
        gGShutter.members.forEach[s|
                s.sendCommand(receivedCommand)
                Thread::sleep(200)
        ]
end

[Z0l (Zoltan Orosz)]

Solved it here’s the working code:

rule "GF proxy roller"
when
	Item ProxyRollerGF received command
then
	gGShutter.members.sortBy[ name ].forEach[s|
		s.sendCommand(receivedCommand)
		Thread::sleep(200)
	]
end
