I recently started exploring the Fibaro Wall Plug Switch and noticed something interesting while configuring it in Habmin. The device provides two different items for monitoring power consumption: Sensor (power) Energy Consumption (SensorPower) and Electric meter (watts) (ElectricMeterWatts). At first glance, I thought they served the same purpose, but upon closer inspection, I realized they display different values. This made me curious about the underlying differences between these two sensors.
After some research and consulting the Fibaro manual, I discovered that SensorPower measures the instantaneous power consumption, providing real-time data on how much energy the device is currently using. On the other hand, ElectricMeterWatts accumulates the total energy consumed over time, giving a cumulative reading. This distinction is crucial for understanding both the immediate and long-term energy usage patterns of your devices.
For example, if you want to monitor how much energy your appliances consume during peak hours or over an entire billing cycle, ElectricMeterWatts would be the more useful metric. Meanwhile, SensorPower is ideal for实时监控设备的即时功耗，帮助你快速识别高能耗设备。
This discovery has been incredibly helpful in optimizing my energy usage and identifying areas where I can reduce consumption. If anyone else has questions about these sensors or tips for effectively monitoring energy usage, I’d love to hear your thoughts!
