The preview of the new firmware
We are about to release a new firmware version soon, which includes many feature upgrades. Here's a "preview" in advance.
Single-phase Meter Now Supports Power Factor, Frequency, and Reactive Parameter Testing
The last two data points in the data array represent frequency and power factor.
Under EA, the Reactive array contains three values representing reactive power, inductive reactive energy, and capacitive reactive energy.
Q (Kvar): reactive power, where a positive value indicates inductive and a negative value indicates capacitive
KVARh: reactive energy, with each phase containing two KVARh values for inductive load and capacitive load.
The API for enabling reactive power testing on the WEM3080 is the same as that of the WEM3080T, implemented through /api/reactive.
Note: Power factor and frequency can be obtained by upgrading the WiFi firmware. To measure reactive parameters, the latest version of the WEM3080 is required.
All Meters Now Support MQTT Discovery, and the Minimum MQTT Publish Interval Can Be Adjusted to 1s (Previously 6s)

For the 3-Phase 3-Wire Delta Connection Meter WEM3080TD
The WEM3080TD is used in three-phase delta connection systems, meaning there is no UN port due to the absence of a Neutral line.
