Zigbee rotary knob 240V

Hello everybody,

I’m looking for Zigbee rotary knob (maybe even wifi?) for controling smart bulbs (Ikea Tradfri) and there are plenty of them. But they are dimmers or wireless buttons (I dont want to replace batteries or listen to my wife when it stops working when I’m not at home and she couldn’t turn on the light).
I want to install it to replace current switch so my wife and kids can control it easy.

But since it’s RGB CCT smart bulb I’m looking for ideally rotary knob with option of single/double/triple or long press or buttons around it. So it would be possible to control colors, kelvins or brigtness by phsyical button.
And all that with just sending signal to HA…

Does that even exist or should I just go with some DIY version with trimmer, buttons and ESPHome?

Best regards, MK

You could use a dimmer and just not connect the output of the dimmer to the bulb, but instead feed it with live.
We have two of sunricher hk-sl-rdim-a, they work fine but they do not support double, triple or even long press.

Can you provide a link for it?
And does it report to HA the position of turn and step? You use it without connecting output too?

Hmm…
I have a hard time finding an official page for it, I can find it in a store like this:

But that might not be of much help.

But it also works without neutral if you use a bypass.

This is what I get from the device.

The light is a light entity with a brightness attribute.

No I have not connected it that way. I use the dimming to dim the lights connected to it

Yea this is pure Triac dimming probably, wouldn’t work without output since it’s not sending data of actual “dimming”.

6

Could be true.
I have not tested it, just assumed the brightness attribute would change depending on how you turn the knob.

7

I don’t see brightness attribute?

I’m using my phone I can’t access the attributes.
But it’s there.

It does, and it’s called the Aqara H1 Dimmer/Knob. The wired version is available for sale on AE and is purpose made to control smart lights via zigbee commands instead of directly by wire.

Don’t make the mistake of getting the H2 version, because that one does have a triac for dimming over the wire.

Thank you!
I will look it up and in about a month hopefully test it :smiley:

Hope you didn’t order it without checking whether it’s compatible with your zigbee integration (ZHA or Z2MQTT).

It’s definitely supported in Z2M, but if you’re running ZHA you might not be as lucky & need a custom quirk.

I didn’t order yet, It’s around 50€, but I found some around 42-44€ so checking stores out.
All look the same to me…

But I just got zigbee hub so I only have 4 bulbs on ZHA so if needs be, I’ll just go with Z2M.
Then I’ll see if I will go from WiFi to Zigbee or not.

I recommend you do this ^^

Any particular reason why Z2M not simply ZHA? I have a small home so I don’t think many more devices will fit any time soon.

16

Yep, a major one. Z2M supports more devices & new ones are added much more frequently than ZHA.

You’ll probably have some teething issues setting it & MQTT up (almost everyone does), but you’ll be thankful when you buy a new device and it’s immediately supported instead of having to wait 6+ months for someone to write a quirk, push a PR & get it approved for a HA release.

I received the aqara knob today, I plugged 230V on it and conected via ZHA to see what I get. I get 3 light switches and…thats it. No dimming or turning or double press.
Only single press which toggles all 3 light switces

And why is device Router?

Did you try and click on the actual lightbulb icons?
Or look at the developer tools for this entities?

19

Yes, I only have on/off option and entities are only those on the picture (3x light, power, consumption total, firmware and identify and temperature which is always 0,4C)
I’m guessing I’m gonna need to migrate to Z2M

And another thing, checking zha_event nothing shows, even single press which toggles relay and shows under activity.

And under visualization there is no “line” from knob to any other device, not even main USB dongle.
