【求助】7231n电量读取问题

你好，目前再看tuyaos_demo_application_driver电量统计demo。我使用的是bl0942 目前遇到的问题是读不出来负载的数据，能读到输入电压，负载的电流和功率都为0.
想问一下 //set environmental parameters 这个里面的 （如图）
ele_env.voltage = 2200; // 220.0v
ele_env.current = 392; // 0.392A
ele_env.power = 864; // 86.4w
ele_env.resval = 1;
应该是用来校准的吧？因为目前再调试阶段，还没办法校准，那几个参数应该怎么填？读出来的负载数据是0跟这几个参数有关系吗?谢谢~

你好这个demo 有点问题，请问使用的TuyaOS版本是多少的，我更新下这个demo。
正确的电量统计示例如下：
tuyaos_demo_application_driver/src/examples/example_drv_ele_energy.c

你好，我用的3.8.5.但是好像最新的3.9.0也是这样。
所以，如果不校准，我那个config的函数不用调用是吧？

是的，你可以查看 tdl_energy_monitor 组件的 README 文档的介绍
