[90] MQTT Support

[MeAlbert]

I have a now and then problem left. I get the following message:
27-10-2020 12:04:32node: dc3574e1.4bac9msg : string[41]
"Unexpected token W in JSON at position 16"
27-10-2020 12:04:32node: 5627d816.529848
domoticz/out : msg.payload : Object
{ command: "udevice", idx: 86, svalue: "232W" }
The svalue is 232W and that's not correct and I get an error message.

The strange thing is that suddenly the W error disappears and I get a C error in a temperature device. The input from MQTT is:

domoticz/out : msg.payload : Object
object
Battery: 255
EnergyMeterMode: "0"
RSSI: 12
description: ""
dtype: "General"
hwid: "11"
id: "000B0004"
idx: 86
name: "PV Vermogen Garage"
nvalue: 0
stype: "kWh"
svalue1: "200W"
svalue2: "1300400.0"
unit: 4

It looks that the mistake already starts when domoticz is making the mqtt/out message. Any idea what I can do about it?

Evening,
I have a strange MQTT problem:

I have a wifi dimmer running Tasmota
It is autoDiscovered by Domoticz fine, appearing as a switch with a dimmer slider.

From the domoticz UI, I can set the brightness level, and the dimmer responds. In response, the Domoticz UI updates to match reality.
However, if I toggle the switch from the Domoticz UI, though the light responds, turning OFF / ON as requested, the Domoticz UI does not update

I can only assume that some MQTT response that is expected has not been seen:

Switching the dimmer on using the Domoticz UI icon does indeed turn the light on - but the UI does not change - it still thinks it is off.

Taken from the device logs:

Could the issue be related to the "no value_template" line...?

Hello,
can someone help me to import data from Mqtt to Domoticz.
I want to import data to a specific IDX.
I made a screenshot of MQTT Explorer, but can't figure out how to import these values.

so:
Input to an IDX
Output to an IDX
Flow to an IDX
Watt to an IDX
I want to do it with a Node-RED sequence (flow)
any help would be appreciate
Thanks, Peter

You better create a new topic in the Node-red sub topic to get better help viewforum.php?f=81

Hello @smitex,

I do not understand, why you raise this issue again at this forum this afternoon.
It has been answered yesterday.Do not post the same issue at multiple forums.

See: https://discourse.nodered.org/t/mqtt-da ... -idx/58476

Oh, sorry FireWizard,

I did not jet see you post, thank you very much for you repley,
I will test you nodered flow

In response to the Domoticz WIKI "MQTT - Arduino, Needed! Please Help." I use the sketch (Arduino) which you can find in the forum at:

viewtopic.php?t=38155

The advantage of the sketch is that you only need Mosquitto as a broker and that NodeRED does not have to be installed.

Hi,

I'm not sure if this question already is answered (I couldn't find it at least).
Is it possible to update multiple sensors in one message (MQTT > Domoticz)?

Kr, Paul

[FireWizard]

Hello @Paulus,

To answer your question.

No this is not possible.

In one MQTT message you can only address one idx number and so you can update only one sensor.

See the Wiki: https://www.domoticz.com/wiki/MQTT and specific the chapter MQTT to Domoticz.

Did you resolve this issue?
I am experincing the same, lights are switching on. In the log the switch is on but in the ui it stays off. Restart of domoticz an the ui is updated.
I am on 2023.2.

You may try https://github.com/FlyingDomotic/domoti ... per-plugin. You may use multiple topics on the same device and/or multiple devices on the same topic, and ... more!

And if some functions are missing, don't hesitate to ask for
