Question

我刚刚创建了一个帐户，因为我在使用OpenHAB时遇到了这个问题。我正在关注这个https://openhardwarecoza.wordpress.com/2015/03/29/openhab-mqtt-arduino-and-esp8266-part-3-hardware-arduino-with-ethernet-shield/网站的教程，但由于回复没有帮助我。我决定去这个网站。

我已成功安装OpenHAB并使用它。当我从HTTP页面和Android设备关闭和打开开关时，它工作得很好。但是当我尝试使用Arduino上的按钮手动覆盖时。它没有更新它们中的开关状态。我正在使用OpenHAB版本1.71

的Windows

Openhab服务器注意到按钮有状态更新，但HTTP页面和Android设备中的按钮根本没有改变。我已经使用MQTTlens测试了连接，它可以正常工作。

以下是我的代码

如果有人可以帮助我，我将非常感激。谢谢你的关注！

如果我没记错的话，你应该回复状态为ON或OFF而不是1或0。

您是否可以更改您的arduino代码以重新发布ON和OFF并进行测试？ e.g。

client.publish("/esp1/l1/state","ON");

Openhab不会改变手动切换的状态
