Domoticz

I restarted a few times and its now showing the right values.

I added a second value, and again no value ....

"T_Living": {
"topic": "ebusd/ctlv2",
"key": "ebusd/ctlv2/z1RoomTemp",
"type": "80", "subtype": "5", "switchtype": "0" ,

},

"key": "ëbusd/ctlv2/DisplayedOutsideTemp",
"type": "80", "subtype": "5", "switchtype": "0" ,

}
}

Added a bit of logging after I update the file:

There's an error in T_Outside. It reads "ëbusd/ctlv2". The trema on ebusd shouldn't be there, I assume.

I thought that too, but it is just how it looks, it is an "e" lol. Tried a different one, same result

Something is still not right, no values are read

Good to know: this doesn't happen with at least 2 other plugins I tested. Both based on the legacy framework.

The issue has been resolved in later versions of Domoticz.

I’m running 2024.4. Problem still exists. And so far only with this plugin.

Something is still not right, no values are read, also the values aren't refreshed.

Would it be possible to get a copy of payload sent when device changes?

IMHO, this perhaps a bug in MqttMapper plugin, but it may either be a configuration problem, with wrong "item" specification. That's why, with payload, we can find the right value.

I don't know what you mean with payload? You can have anything you want

When speaking about MQTT, payload is message content related to a topic.

Here, the interesting topic is either "ebusd/ctlv2", "ebusd/ctlv2/z1RoomTemp" or "ebusd/ctlv2/DisplayedOutsideTemp".

Content of there topics may help.

To get the content, you may use tools likeMQTT_Explorer or MQTT.fx

Another possibility (if given "ebusd/ctlv2" is the right one), is to set MqttMapper plugin into debug mode (on the hardware page).

Only I don't know what it means

I'm reading (copied from MQTT explorer)
ebusd/ctlv2/z1RoomTemp
ebusd/ctlv2/DisplayedOutsideTemp

And the file:

{
"T_Living": {
"topic": "ebusd/ctlv2",
"key": "ebusd/ctlv2/z1RoomTemp",
"type": "80", "subtype": "5", "switchtype": "0",
"mapping": {"item": "", "multiplier": 0.1}
},

"T_Outside": {
"topic": "ebusd/ctlv2",
"key": "ebusd/ctlv2/DisplayedOutsideTemp",
"type": "80", "subtype": "5", "switchtype": "0",
"mapping": {"item": "", "multiplier": 0.1}
}
}

I found, and fixed, the issue with the disappearing settings as a.o. reported by @Hencor in this post.

Believe it or not, but this is caused by the name tag in the plugin definition: Apparently this is not (all) treated as a string. The word "LAN" seems to have a special meaning in Domoticz. When changing the name to something without "LAN" everything works as expected.

So if the plugin definition is for example changed to: all works fine. As can be seen below.

Thanks for the log.

Update is not really an update. This is the MQTT Ping sent to Mosquitto, and Mosquitto's pong answer. IT normally happens every minute.

To see payload, you have to wait for the (external) device to send it. It will be prefixed by "onMQTTPublish: '", followed by topic ''ebusd/ctlv2'', and finally the value (you have to set debug to "Extra verbose" before that.

If nothing is received after more twice expected update period, you may gave the wrong topic.

To find the right topic, use tool like MqttExplorer (https://mqtt-explorer.com/), connect to you MQTT server (giving IP and authentication),wait a bit for messages to be received, and explore things received by ebusd/ctlv2 topic, including its sub-topic(s). Try to locate data you want to get, and write down the full topic. This topic should be inserted into MqttMapper configuration file.

You may want to share it here, either publicly or through private message.

Hard copy of MqttExplorer screen showing this data may help.

I could send you the file of the picture of MQTT? I don't know how to get it on here

If I put the file error logs in "extra verbose" extra I don't get anyting?

It is not reading the sValue?

There is an attachment tab for images under the submit button if you select full editor when typing a new reply.
Also check the mqtt debugging section of Domoticz wiki https://www.domoticz.com/wiki/MQTT#Debugging_MQTT

I transfered an image lol

MQTT is fine, I can't get the sValue of the temperature

Thanks !

Real topics are "ebusd/ctlv2/z1RoomTemp" and "ebusd/ctlv2/DisplayedOutsideTemp", so you configuration file should be something like: With that, data should be collected.

Wow, I must have tried a million types of input files, but not this one .....

You solved it thanks a lot!

MISS & KISS (Make It Simple Stupid / Keep It Simple Stupid

it partially works for me . I get data from a BME680 IAQ sensor from an Arduino D1 Mini. I have transfered the values to the Mosquitto broker and the device appears in Mosquitto. For some reason the Baro device is not available in the Domoticz GUI and for humidity I have not found any type to get the values updated . I have gambled arround several hours with the MqttMapper.json file but do not get a satisfing result. What am I doing wrong?
