Hi,

on my WEM3080T with last firmware, I work with mqtt without issues, but there is no more frequency on transmitted data.

Is it normal ?

Thanks.

I’m guessing you’re using MQTT discovery, correct?
And you’ve noticed that the data published to the Home Assistant MQTT broker does not include the frequency attribute?

If so, that’s actually normal behavior.
When the MQTT discovery option is enabled on the device, the data format changes to comply with Home Assistant’s requirements(it has not inlcuded the data of frequency this time,as we thought the frequency is fixed). If that option is not enabled, the data retains its original format and structure(the data of frequency is included in the JSON array https://www.iammeter.com/newsshow/energy-meter-json-value).
