Which battery powered knob do you use?

[andreapx]

I need a battery powered knob to dimmer some lights, which one do you use?
I've seen this one that's pretty inexpensive, but it's not compatible with Zigbee2mqtt yet.
The Tuya ERS-10TZBVK-AA doesn't seem to be available anymore.
Thanks!

Hi there,
I have a very similar one, simple called "Smart Knob Dimmer" (TS004F _TZ3000_402vrq2i). Seems that inside they are all Tuya based, not sure what the differences are. Zigbee2MQTT treats most if not all of them as ERS-10TZBVK-AA.
In case you did not only mean rotary knobs: For most of our house we use the IKEA Tradfri on/off buttons and some RODRET switches. Holding on/off can be interpreted as brightness up/down depending on how you set up your HASS automation.
Hope that helps.

I can't find it, could you please send me a link?

I meant rotary knobs, sorry.
I've tried using the the hold function, but I'm not a real fan (I hate that method! 🙈😆)

I just got one of these TS004F _TZ3000_402vrq2i rotary knobs from AliExpress and ended up here with Google naturally.

Z2M will add the device but I get "Not supported". Exposes is empty. See screenshots.. @djurny does yours work in Zigbee2MQTT? Can you share your generated_external_definition?

Hi @carrierone,
The easiest way is to upgrade zigbee2mqtt to v1.42.

If you cannot, the external definition I used is actually from @Velomeloman, who merged it into v1.42.

See #23543 (comment).

Oh great, thank you I'll give that a try! 🙂
