Mike - 尝试这个项目,如果您在SNMP方法上放弃了,请告诉我它是否适用于您(理论它应该与我较小的10kW版本相同的RS232 / USB协议) -以通过MQTT与家庭助理的volver逆变器(Voltronic,Axpert,MPPSolar Pip,Voltacon,Effekta等)的以编程方式读取数据 - 与RS232和USB合作!19463331伟德国际
它旨在在Docker中运行,因此它可以部署在逆变器旁边的廉价SBC(如橙色PI)上,然后通过MQTT与HA通信...
您还可以使用HA以这种方式向变频器发送命令(如改变电池截止和浮动电压,充电模式等)。
If you live in a hot climate like me (Australia) I’d suggest also adding in a DHT22 temperature sensor to your battery box (assuming you have one) and wiring it to the PI also - this way if the batteries are above normal temperature, you can programmatically change the charge voltage/amps on the inverter (via a HA automation) so that you don’t damage them when charging them in at hotter temperatures
