It works.
I made a mistake at Copy from Rule.
The word Rule1 must not go in Tasmota Console.
To date I have had no experience with Rules.

Is from Tasmota console
Updates every 3 sec.

16:45:36.422 MQT: tele/Windmesser/STATE = {"Time":"2023-11-30T16:45:36","Uptime":"0T04:15:38","UptimeSec":15338,"Heap":24,"SleepMode":"Dynamic","Sleep":50,"LoadAvg":19,"MqttCount":1,"POWER":"OFF","Wifi":{"AP":1,"SSId":"Rafffaelo","BSSId":"38:10:D5:D2:6F ...

I use the Rule from javalin:

Rule1
on tele-TX20#Speed#Avg do var1= 5.14444444*%value% endon
on tele-TX20#Speed#Max do var2= 5.14444444*%value% endon
on tele-TX20#Dir#Avg do var3 %value% endon
on tele-TX20#Dir#AvgCard do publish domoticz/in {"idx":592,"svalue":"%var3%;%value%;%var1%;%var2%;0;0 ...

MQTT receives data but does not send it to domoticz

in tele is TX20 visible but not in domoticz/in

TX20 is not visible in MQTT Explorer.

I did all of that.
This message comes in
Domoticz Protokoll:

2023-11-29 10:46:35.665 Error: MQTT Gateway Wind: unknown idx received! (idx 0)

MQTT Client Gateway is OK. other devices work.

In MQTT Explor I see the data.
How do I get the data on IDX?

Hello,
thanks for the reply.
I took the rouls from above. adjust idx.
I don't see the data arriving in Domoticz.
Where can I look?

Hello,

After a long search I found and bought a TX20.
I've been trying to integrate the data into Domotcz for days.
I don't get any ads in Domoticz.
Do I still need dzVents script?

Thank you for your answers.
