Message | Unit | Description
---------------|------|-----------------------------------------------------
TotalStartTime | Date | DateTime of calculation for Total
Total | kWh | Total Energy usage including Today
Yesterday | kWh | Total Energy usage between 00:00 and 24:00 yesterday
Today | kWh | Total Energy usage today from 00:00 until now
Period | Wh | Energy usage between previous message and now
Power | W | Current effective power load
ApparentPower | W | Power load on the cable = sqrt(Power^2 +
| | ReactivePower^2)
ReactivePower | W | Reactive load
Factor | | The ratio of the real power flowing to the load to
| | the apparent power in the circuit
Voltage | V | Current line voltage
Current | A | Current line current

How to “Flash TASMOTA on Sonoff POW R2”
-
Based on the 2.5.2 Arduino ESP8266 core
Firmware binary for 4M flash devices only! - This binary will NOT work on 1M flash devices
sonoff-4m.bin
another way to flash the Sonoff POW R2 by sending the bin file using ESPTool.
