node-red通过ssh 登录设备获取信息并建立传感器，有没有成...

michlu

我想在node-red里面建立这样一个流程：首先通过ssh登录我的华硕路由器，定期执行命令获取相应的信息，并将其储存在传感器中，最终通过hass的dashboard展现出来。不知道有没有成功的案例？


关键是node-red如何调用ssh，并执行相应的命令

asdasfhth

exec可以执行ssh命令，免密方式ssh，如果nodered是docker方式安装的，要把home文件映射到本地，把keygen储存好，不然每次重启nodered，keygen密钥就没有了，ssh命令没法执行。读取路由器信息就比较简单了，主要解决ssh的问题

前两天刚刚实验成功

后来找到一个bigssh的节点，挺好用的

请问可以发送命令给ESXi执行吗
