Support events for Philips Tap Dial Switch

[sjafferali]

The new philips tap dial switch does not emit an event on deconz_event in home assistant when the dial is rotated. The buttons on the switch do however emit events.

Support was added in deconz for this switch in dresden-elektronik/deconz-rest-plugin#6160 .

I opened an issue in home-assistant/core#76427, but was directed to resubmit here.

Sorry, I've been busy and will keep busy until next week. I haven't forgotten this.

I've bought a tap switch myself, just need to get a deconz 2.18 instance running

[Kane610]

Would you mind sharing your thoughts on how you would like it working?

[sjafferali]

Thanks @Kane610 .

I am not intimately familiar with the implementation, but querying the rest API shows the tab dial state.

{
    "config": {
        "battery": 43,
        "on": true,
        "reachable": true
    },
    "etag": "XXXXXXXXXXXXXXXXXXXXXXXXX",
    "lastannounced": "2022-08-23T20:04:23Z",
    "lastseen": "2022-08-23T20:24Z",
    "manufacturername": "Signify Netherlands B.V.",
    "modelid": "RDM002",
    "name": "RelativeRotary 16",
    "state": {
        "expectedeventduration": 400,
        "expectedrotation": 317,
        "lastupdated": "2022-08-23T14:55:31.188",
        "rotaryevent": 2
    },
    "swversion": "2.59.19",
    "type": "ZHARelativeRotary",
    "uniqueid": "XXXXXXXXXXXXXXXX"
}

If we could emit a deconz_event in home-assistant with these state updates, similar to the buttons on the switch, that should be sufficient for automation purposes.

There was also a similar issue for this switch in the home-assistant repo, that was recently resolved, which may be helpful. home-assistant/core#75082.

Is it possible to get the number of steps, like the event is retrieved here? It was implemented like this in the HA Hue integration. It looks like it makes its usage for dimming very easy. Thanks!

I will need to investigate it closer ones support is released

[krusemedia]

Any news on this? Can we help?

[Kane610]

Nope sorry, I've refrained from upgrading to 2.18 due to what seem to be a memory leak in the system. I really want to progress on it :)

[krusemedia]

Does the problem still persist with v2.18.2 ?

I've asked the devs and await more details

[chris-nite]

I'm also desperately awaiting support for dial movements in deconz. Right now i'm on 2.18.2 and so far, deconz still won't emit any events (or exposes them via API), when the dial is turned. All the other button-functions work as expected.
Are there any news about this?
Thanks in advance for your support and best regards.

[Kane610]

I have been fully occupied with other things but plan on upgrading to 2.19.1 so I can get started.

The more suggestions about how you want it exposed the better for me when I get started. I won't promise it but I would like to get the support in with 2022.12 release

[Mincka]

I think it depends on the exact meaning of expectedrotation (see this post).

A Hue event looks like this:

"relative_rotary": {
              "last_event": {
                "action": "start",
                "rotation": {
                  "direction": "clock_wise",
                  "duration": 400,
                  "steps": 15
                }
              }
            }

I don't know how the expectedrotation and the steps are linked.
I observed that one rotation click equals to 15 steps. I count 66 clicks for a 360° rotation.
But it seems possible to get values that are not multiples of 15 for expectedrotations or steps.
Maybe if you compare both for a single step, you will understand how they are related. In the end, I think the goal would be to get the same presentation than the one of the Hue API, maybe with even more precision if possible.

The steps give the rotation amount between two updates that are done every 400ms. This means that even when I move the dial quite fast, I can get the total amount and catch up with my automations (increase brightness / volume by x steps, open/close cover for position+x steps, seek forward in music/video for x seconds as steps...).

Sadly, there's a pending bug in the Hue integration that ignores identical events to it doesn't make the dial play very well for now. Hopefully, once we have it in Deconz Rest API, it will be perfect. 😄
