Use rollershutter_position_profile for rollershutter-item without channel

Add-ons Other
1

I use the great rollershutter-position-emulation from Jeff James that’s in the Add-On-Store for all my dumb somfy rollershutters. Works great.

But: I have one shutter (warema) where I have to send the rf-signals low-level by a rule. This rule is triggered if the corresponding rollershutter item changed. So this item is not connected to a thing but has it’s hardware connection only via rule.

Is it somehow possible to use the rollershutter_position_profile for this item although it’s not connected to a channel?

2

No. Profiles live on the Link, not on the Item or the Channel. If you don’t have a Link, you can’t have a profile.

3

Yes, understood.
I was looking for a trick to use the profile (because it’s great) anyway.
Wouldn’t it be possible to connect a dummy-channel (just anything without function) and then check the updates of the item that are done by the profile?
I’ll give that a try and report.

4

And do what with it?

The Profile intercepts and modifies state updates coming from the Channel to the Item, and in some cases from the Item to the Channel (e.g. transform Profile). The follow profile links two Channels (i.e. an update from one Channel becomes a command to another Channel in addition to an update to the Item).

How could a dummy Channel be used here? The profile is only going to change the data going back and forth between the Item and the dummy Channel. Your rule won’t see it.

I would like to use the position-emulation that is implemented in the profile, so that I don’t have to re-implement it. (Actually I already did that, but the profile works better than my emulation)

The profile works in both directions:
It processes the commands to the items and updates the state of the item.
Here the a part with the callbacks from the source-code of the profile:

        if (targetPos == position && !isMoving()) {
            logger.debug("moveTo() position already current: {}", targetPos);
            if (targetPos == 0) { // always send command if either 0 or 100 in case it is not already in that position
                callback.handleCommand(UpDownType.UP);
...
        } else if (Math.abs(posOffset) < configuration.precision) {
            callback.sendUpdate(new PercentType(position));
            }

I’ll give it a try tomorrow.

Got it working (thanks for the push by telling me it’s not possible :wink:). The rule processes position commands by starting the motion and then waiting for the matching change event caused by the profile. UP, DOWN and STOP are just passed through.
If anybody is interessted here the rule as blockly:
