- You can build your own using ESPHome's [CT Clamp Current sensor](https://esphome.io/components/sensor/ct_clamp.html) or energy meter sensors like the [ATM90E32](https://esphome.io/components/sensor/atm90e32.html). For the DIY route, check out [this video by digiblur](https://www.youtube.com/watch?v=n2XZzciz0s4) to get started. - You can build your own using ESPHome's [CT Clamp Current sensor](https://esphome.io/components/sensor/ct_clamp.html) or energy meter sensors like the [ATM90E32](https://esphome.io/components/sensor/atm90e32.html).

- Using a Raspberry Pi, you can use a CT clamp HAT from LeChacal called [RPICT hats](https://lechacal.com/docs/RPICT/Raspberrypi_Current_and_Temperature_Sensor_Adaptor/). They can be stacked to expand the number of lines to monitor. They also provide Active, Apparent, and Reactive power and power factor for single-phase and three-phase installations. They integrate with Home Assistant using MQTT.
_Attention! Installing CT clamp sensor devices requires opening your electrical cabinet. This work should be done by someone familiar with electrical wiring and may require a licensed professional in some regions. Your qualified installer will know how to do this._ _Attention!
