Unable to find power read channel on Tasmota smart plug (Nous a1t)

Setup, Configuration and Use Beginners

I connected a tasmota based smart plug via mqtt to openhab and the commands work. I don’t know how to read the current power output. I don’t know what channel to use.
I use

mosquitto_pub -h 192.168.178.86 -m "off" -t cmnd/tasmotaPlug2/power -d

which works.
I try something like

mosquitto_pub -h 192.168.178.86 -m "" -t stats/tasmotaPlug2/power -d
mosquitto_pub -h 192.168.178.86 -m "" -t tele/tasmotaPlug2/power -d

But no success. The Tasmota web page shows the value, but where do I get to know the channel name?

Thanks

Maybe use an mqtt client like http://mqtt-explorer.com/ to view available payload

Aha!
It appears to be tele/tasmotaPlug1/SENSOR. The mqtt explorer shows values for that:

{
  "Time": "2022-12-29T13:33:47",
  "ENERGY": {
    "TotalStartTime": "2022-12-28T20:51:52",
    "Total": 0.074,
    "Yesterday": 0.058,
    "Today": 0.016,
    "Period": 0,
    "Power": 1,
    "ApparentPower": 3,
    "ReactivePower": 3,
    "Factor": 0.32,
    "Voltage": 230,
    "Current": 0.015
  }
}

But shouldn’t I be able to read those values, maybe with:

mosquitto_sub -h 192.168.178.86 -t tele/tasmotaPlug2/sensor

?
Anyway, thanks a lot!

Don’t mix up your plug1 and plug2

Also the topics are maybe case sensitive :thinking:

They definitely are. It’s SENSOR in capitals.

Thanks @all

mosquitto_sub -h 192.168.178.86 -t tele/tasmotaPlug2/SENSOR

works. And yes, it is case sensetive.
