Read payload from Tasmota switch [SOLVED]

Setup, Configuration and Use Beginners
#1

Good evening everyone
I can’t get OH2 to read the ON / OFF status change from the topic:
stat / boiler_room / MQ2
I use the broker mosquitto 1.1
The payload comes from a NODEMCU peripheral, configured with TASMOTA11, and the MQ "sensor that sends the payload is connected to the GPIO12 as Switch1.
With MQTTlens I read the payload (ON OFF) , so the message is sent correctly, but OH does not change the state of the switch. Some help … thanks
item:

Switch sensore_caldaia        "sensore caldaia "                        <sensore_fumo>	 (sensori)    		    {mqtt="<[mosquitto:stat/locale_caldaia/MQ2/power:state:default]"  }

sitemap:

 Switch item=sensore_caldaia```

Please confirm the MQTT Binding version that you have installed. Your syntax is for v1 of the binding…

#3

Mosquitto rel 1.4.15

#4

That’s your MQTT broker version. What’s the version of the MQTT Binding in openHAB?

#5

ah…ok :grinning:
MQTT binding 1.13.0

#6

no help?

#7

Not many people left still familiar with binding version1.x

Does your broker config work i.e. have you other mqtt Items that work?

Always worth making a temporary String type Item, with the same binding link, in case the payload is not what you expected (we have not seen your mqtt messages yet).

#8

I have other Tasmota peripherals that work perfectly with my broker. In this case with MQTTlens I see that the payload corresponds to ON and OFF. What I can’t do is configure the right topic to read from OH the payload of switch1 connected to GPIO12 in tasmota, to activate a switch type item

Reading This old thread might help.

#10

How about sharing that. It’s really difficult to help you.

#11

tasmota consolle:

16:10:25.811 RUL: SWITCH1#STATE=0 performs "publish stat/locale_caldaia/MQ2 ON"
16:10:25.817 MQT: stat/locale_caldaia/MQ2 = ON
16:10:27.147 RUL: SWITCH1#STATE=1 performs "Publish stat/locale_caldaia/MQ2 OFF"
16:10:27.153 MQT: stat/locale_caldaia/MQ2 = OFF

mqtt.fx:

payload_ON
payload_ON771×214 13.2 KB

payload_OFF
payload_OFF775×218 14.1 KB

#12

These topics are not the same

#13

yes I see it, the first is the OH item files
to control a peripheral with TASMOTA the topic must indicate what to control … for example POWER controls the main relay, LWT the network status etc.
The second line is what I read from the terminal of the peripheral which corresponds to the payload which also reads MQTT.fx.
In my case I connected an MQ2 sensor to the GPIO12 and I cannot get the ON / OFF status to be read by OH because I don’t know which is the right topic

 Switch sensore_caldaia             "sensore caldaia "                        <sensore_fumo>	    (sensori)    		    {mqtt="<[mosquitto:stat/locale_caldaia/MQ2/???????:state:MAP(MQ2caldaia.map)]"  }

i try SWITCH SWITCH1 POWER1 STATE …but not read from OH

basically I need OH to read the feedback from the switch

#15

Soooooo - what happens when you correct your openHAB Item to use the exact topic highlighted by @rossko57 (the one I’ve quoted)?

#16

nothing

#17

Confirm that such a definition does not work:

Switch sensore_caldaia        "sensore caldaia " { mqtt=">[mosquitto:cmnd/local_caldaia/MQ2:command:*:default],
            <[broker:stat/local_caldaia/MQ2:state:default]" }

Made this up from the old thread I linked above and the MQTT message as printed from your tasmota console.

#18

this work!!! thanks guys, I was going crazy for such a trivial thing!!!

   Switch sensore_caldaia                 "sensore caldaia "                                                             {mqtt=">[mosquitto:cmnd/locale_caldaia/MQ2:command:*:default], <[mosquitto:stat/locale_caldaia/MQ2:state:default]" }

Such as reading the answers you got?
