openScale

[Varazir]

Hello,

Have anyone used openScale ?

It looks like this in the MQTT but nothing comes up in Domoticz.

and

[waltervl]

Please post the complete config payload as text. There is a copy icon next to "Value" to copy it in MQTT Explorer
And I am not sure Domoticz supports device configs (with in it multiple components)

[Varazir]

Not sure if it's going to be valid anymore as the app stoped working with the scale.

Maybe better buying a new scale. I would one that the RPi can read direct and translate to MQTT or custom use plugin.
Don't like to have an app that need to be running on my phone.

It looks like Domoticz does not support these kind of Config topics.
You could try to create a config topic manually with MQTT explorer for the scale.
The MQTT part is in the App or does the scale sends data to MQTT?

You mean MQTT mapper ? I guess I could do that.

It's https://play.google.com/store/apps/deta ... e.sync.oss app that syncs data from the main app.
I just read on the github for the app that there are a issue with just my scale. https://github.com/oliexdev/openScale/issues/1246

With MQTTMapper is also an option, but when you send With MQTT Explorer just a different (retained) MQTT config topic message that is compliant with Domoticz it will create the device(s). https://www.home-assistant.io/integrati ... -discovery

Never done that with MQTT Explorer
So as long as the device it create it will be able to read the values each time they are updated ?

[waltervl]

Yes and when you send it as a retained MQTT message it will also be available when Domoticz restarts. You also have to delete the retained message from the MQTT server when you want to remove the device from Domoticz, else it will re-appear.

Do you have an example?
Don't understand what to do

[waltervl]

Sorry, the examples are in the home assitent llink I mentioned before. I do not use MQTT and even MQTT AD.

If you wish to do that with MqttMapper, where's an example reading weight:

Code: Select all

{
    "Scale weight": {
        "topic": "openScaleSync/measurements/last",
        "type": 93, "subtype": 1,
        "mapping": {"item": "weight"}
    }
}
