  • Issue of the topic: wattage on Nous A1T (Tasmota 12.4.0)

I don’t know why, I don’t get any values for the current energy. The item itself is online and the switch channel works. I also tried with ‘…Voltage’ and ‘…Power’ instead of ‘…Current’.

Hi,

Can you use mqtt explorer to connect to MQTT server and see what is the values send by your NOUS A1T ?

After rebooting it seems to work, now thers’s a line shown, but the values are all 0.
Here are the values of the mqtt explorer:

I really don’t know why. But after changing between different states (total, voltage…) it seems to work. But there is a big lag of around five minutes when I switch devices on and off.

Hi,
I think, that’s the standard, when you read just the “tele” topics, as Tasmota sends the “tele” topics based on the content of “teleperiod”. Standard is 300, which are 300 seconds aka. 5 min. Change “teleperiod” to eg. 15 and you will see updates every 15 seconds.
And to get the ON/OFF status right away , you should use the “stat” topic.

You’re right! Thank you!
