Core: Tradfri Wireless Dimmer shows up as Binary Switch
Home Assistant release with the issue:
0.84.3
Last working Home Assistant release (if known):
Operating environment (Hass.io/Docker/Windows/etc.):
Docker on Ubuntu 16.04
Component/platform:
https://www.home-assistant.io/components/zha/
Description of problem:
I successfully paired a Tradfri Wireless Dimmer with my Elelabs ZigBee USB Adapter using the ZigBee Home Automation Component. Unfortunately the Dimmer shows up as a binary_sensor instead of a normal (level) sensor.
Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):
(I know this database_path does not make a lot of sense in Docker, but it shouldn't affect this problem)
zha:
usb_path: /dev/ttyUSB0

These are essentially remotes. This is how they currently work. I can create a handler for them that will make them emit events as well. Currently, this is "functioning as implemented" and is not a bug

Ok. So would the expected behavior be the binary_switch to change its state from 0 to 1 as I turn the dimmer? Because I never achieved this. Or what does this binary switch represent?
Thanks for your answer by the way :-) Oh and events would be awesome ;-)

hrm... click on the entity and tell me if the level attribute on it changes as you turn the dimmer. Does the device have a clickable button as well?
The way this was implemented originally isn't very compatible w/ a lot of devices because it doesn't differentiate between toggle style buttons and multifunction on/off devices like the Osram dimmer. The coming event support will make this much cleaner. Hopefully we can get direct binding and groups done at some point soon as well. Both of those features would be even better.

No I actually never witnessed the level to be anything other than 0 no matter how far I turn the dimmer. It does not have any button other than the reset button.
The reason I try to get this to work in HA is because Ikea wont let me use two dimmers for the same light (group).
Thank you for your work. If you need me to try anything, let me know.

I have to pick 1 up to figure this out. Stay tuned :)

The 5-button Tradfri wireless remote also doesn't seem to be properly supported (or at least, I can't seem to figure out how to get HA to respond to anything that it does).
Leaving this here, because it seems closely-related, but I can open another issue. As far as I can tell, I haven't come across anybody who's using HA's "built-in" ZHA with the Tradfri remotes...

I purchased just the circular dimmer with no buttons to investigate. I tried several times to get it directly from ikea’s site but it won’t let me check out so I got it from amazon. It should be here Wednesday. Once I have that working I’ll take a crack at the 5 button one. If you don’t mind, can you unpair it and then join it again and post the SimpleDescriptor log entry?

@dmulcahey
I've paired/unpaired them a few times, and still have the logs handy. (I have two remotes, just in case the logs look confusing). I'm guessing the exceptions are being thrown due to the pairing/unpairing (and might not actually be relevant to anything).

So, this came in yesterday. I got it paired and the device spams messages at a pace that is insane. I have to dig into the commands a bit to see what I can do for this. I'll let you know when I have more info.

@seimsel this may only end up working once I release direct binding support. I'm still not positive though. Hopefully i'll have some time this weekend to experiment a bit more.

Don't know if it helps (I'm following this because I might want to switch components) but this dimmer works for me with deconz. Maybe you can take a look for inspiration there?
It currently sends out events when turned, which I convert to dim/brighten actions using appdaemon.

@sophof what’s in the events? Can you provide the content of a couple?

I'm currently at work, but I'll paste na bit of the debug output later.

Not sure if this is of use to you, but here is the DEBUG output of pydeconz when I turn the device clockwise. So this is coming from the deconz component in hass:

It also seems to work in Zigbee2mqtt by the way. I ordered the necessary components to try it out but it takes weeks if not months to ship from china (Aliexpress). And then you need to flash the firmware yourself. The ZHA component is much easier to setup. Its also much easier than deconz. Which is why I still think its very valuable to get this to work. I’ll keep you posted about my experience with Zigbee2mqtt

If it is working with those we’ll be able to do it... will just take some time.

So, good news... an unrelated change we made to make remote devices work better in general actually ended up adding support for this! That being said, we need to find a way to buffer the events because this device sends insane amounts of traffic. To pair the little round puck, take it apart and press the button 4x and place it on a flat surface so it doesn't try to send any additional traffic. Then permit joining in zha. After it joins successfully you should get events like these:

This is in dev already and will be in .86 :)

You guys are awesome 😊

It works :-) Just to verify: It is not yet possible to connect this event to a light without an automation, right? Is what you refered to as "direct binding support"?

Correct... I was going to make this available ASAP but we need to redo the core of ZHA to clearly separate the internals of ZHA from HA. Events are the way to go for now :)

I'm running 0.92.2, with a virtualenv installation. I managed to pair the dimmer. It shows in core.entity_registry as
{
"config_entry_id": null,
"device_id": null,
"disabled_by": null,
"entity_id": "zha.ikea_of_sweden_tradfri_wireless_dimmer",
"name": null,
"platform": "zha",
"unique_id": "ikea_of_sweden_tradfri_wireless_dimmer_fe9a4c79"
}
But the level is only ever either 0 or 254.
Am I missing anything?

@fheinz check https://github.com/home-assistant/home-assistant/issues/19450#issuecomment-454389494
Currently Ikea remotes or motion sensors are not supported. It is being worked on, but the progress is slow.

I might be interested in contributing to this effort, but I have been unsuccessful in my search for any documentation on how to get started hacking on zha. Any pointers?

I reckon you already found this: https://developers.home-assistant.io
Not specifically ZHA but Home Assistant in general.

was this something that was ever implemented got a hold of these and connected it but doesn't report anything but battery, was able to get the firmware updated

As far as I know direct binding for these is not supported yet. But it should be possible to create an automation that listens for a zha_event and sets the brightness of a light (or even changes something else).

If it is working with those we’ll be able to do it... will just take some time.
