Aqara W100 sensor/thermostat — temperature and humidity sensor Zigbee Matter Thread

[mutmut]

To test the button code, I will create a new scene without a trigger.
Then you add a Get state of the + button.
And you send the result to Telegram.

Before manually running the scene, you click your + button,

[bjm]

That doesn’t do anything.

I have the values in zigbee2MQTT
Single Click

Double Click

Long Press

Long Press Release

[bjm]

Even though the W100’s buttons don’t work, I’m trying to move forward and get it to display the value of my fictitious thermostat on it.

D’après www.domo-blog.fr il faudrait que je mette se code

- action: mqtt.publish
    metadata: {}
    data:
      payload: \u003e-
        {

        "external_temperature": {{
        states('sensor.ref-temperature-sb-chambre-6') | float(0) }} }
      topic: zigbee2mqtt/w100/set

But I don’t see where or how to put it.
Il en est également question sur Jeedom encore une fois, je ne vois pas comment faire cela avec Gladys.

[mutmut]

This code is for Home Assistant if I’m not mistaken, so it’s useless for Gladys.

I got this from the W100 docs on z2m:

External temperature (numeric)
Value for external temperature sensor.
Value can be found in the published state on the `external_temperature` property.
It's not possible to read (`/get`) this value.
To write (`/set`) a value publish a message to topic `zigbee2mqtt/FRIENDLY_NAME/set` with payload `{\"external_temperature\": NEW_VALUE}`. The minimal value is `-100` and the maximum value is `100`. The unit of this value is `°C`.

In my opinion, you should use the action Envoyer un message ZIGBEE2MQTT, set the appropriate topic and the value you want.
The topic would be something like: zigbee2mqtt/ref-temperature-sb-chambre-6/set
and the value: {\"external_temperature\": 26}
or: zigbee2mqtt/ref-temperature-sb-chambre-6/set/external_temperature
and value: 26
But here I’m out of my depth because I’m not a dev

Or make an HTTP request, with a POST (I guess but I’m not sure) and the appropriate http command (and again, I’m stuck there).

To check that the MQTT command/value is correct, I use MQTT Explorer for macOS.

And if a dev happens to be around to help, that would be great.

That’s right, you need to use the « Send a Zigbee2mqtt message » action:

[pierre-gilles]

Thanks for the video @bjm, it’s much clearer in the video

I see that the buttons work with 4.59, that’s great.

Don’t hesitate if you have any other questions

[mutmut]

Great video! I honestly thought until the end we’d see 24 show up on the

[pierre-gilles]

@mutmut

@pierre-gilles I notice on @bjm’s video that the module’s temperature is 81.2, so in Fahrenheit and with no unit.

Yes we’re talking about it in another thread: Valeur Fahrenheit parfois affichée sur le tableau de bord sans conversion

[mutmut]

yes I know, that’s why I pointed it out but I’d forgotten it was @bjm too

[bjm]

No, we don’t see the 24 appear because it still doesn’t work; we must not be far off.
Here is my scene:

Sending reference temperature value to W100

Trigger when the reference value is changed after pressing the PLUS button on the W100 (change made by scene post 38)

I retrieve the new reference value

For verification I send it to myself via Telegram

And I send this value to thermo-radiateur-sb-chambre-6, which is the name I gave to the W100 in Zigbee2MQTT

To > Topic

zigbee2mqtt/thermo-radiateur-sb-chambre-6/set

Value sent for external_temperature

{"external_temperature": 
1.1. ref-temperature-sb-chambre-6 (ref-temperature-sb-chambre-6)
 }

But this doesn’t display anything on the W100

[bjm]

@pierre-gilles

I see that the buttons work with 4.59, that’s great.

That’s starting to make quite a list, I even almost asked you what you had named it, I couldn’t find it, maybe we should find a way to make searching easier.

[pierre-gilles]

@bjm

But that doesn’t display anything on the W100

You aren’t using the right action! You need to use « Send a Zigbee2mqtt message »

@bjm

That’s starting to make quite a list, I even almost asked you what you had named it,

The simplest is to show the feature on the dashboard, and see the name it displays when it’s pressed

@pierre-gilles

You’re not using the right action! You need to use ‹ Send a Zigbee2mqtt message ›

Edited but still nothing

In my opinion, you should

[bjm]

@mutmut

Otherwise you can test first:
Send a zigbee2mqtt message
topic: zigbee2mqtt/thermo-radiateur-sb-chambre-6/set/external-temperature
message: 38

Here is the Error message retrieved from the zigbee2MQTT log

2025-05-26 21:08:10z2m: No converter available for 'external-temperature' on 'thermo-radiateur-sb-chambre-6': (38)

[mutmut]

so test with \"38\"
and then with { 38 }
then with { \"38\" }

One of them should work

[bjm]

I had written it wrong
it’s

external_temperature

now it no longer returns an error.
I tested your three proposals still nothing on the W100

[mutmut]

@bjm

I tested your three suggestions, still nothing on the W100

Did you retest with just 38?

[bjm]

yes
I even tried

zigbee2mqtt/thermo-radiateur-sb-chambre-6/set/external_temperature/

zigbee2mqtt/thermo-radiateur-sb-chambre-6/set/{external_temperature}/

I found this, I don’t know if this can help.
