集成你的太阳能板
通过将你的太阳能板集成到Home Assistant中，可以深入了解你的能源生产。
如果你还设置了太阳能预测集成，你将能够看到预期的太阳能生产，并基于计划的生产进行自动化。
硬件
Home Assistant需要知道生产的能源量。这可以通过多种方式完成。
使用CT夹具传感器
Current transformer (CT) clamp sensors measure your energy usage by looking at the current passing through an electrical wire. This makes it possible to calculate the energy usage. In Home Assistant we have support for off-the-shelf CT clamp sensors or you can build your own.
- The off-the-shelf solution that we advise is the Shelly EM
. The device has a local API, updates are pushed to Home Assistant and it has a high quality integration. - You can build your own using ESPHome’s CT Clamp Current sensor
or energy meter sensors like the ATM90E32 . For the DIY route, check out this video by digiblur to get started.
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.
