nest-api - 设置目标温度会在 Nest 恒温器中引发错误

Question

设置目标温度会引发如下错误。我正在使用 php curl 来设置温度。任何帮助表示赞赏。

object(stdClass)#72 (2) {
    ["cmd"]=>
           string(12) "REINIT_STATE"
     ["pod"]=>
           string(5) "rts04"
}

代码:

echo "Setting target temperature...\n";
$success = $nest->setTargetTemperature(150,$device_serial_number);
var_dump($success);

        echo $temperature;
        $data = json_encode(array('target_change_pending' => TRUE, 'target_temperature' => $temperature));
        return $this->doPOST("/v2/put/shared." . $serial_number, $data);

从 setTargetTemperature 调用的 doPOST 函数。从 doPOST 调用的 doRequest 函数。

简单的事情是:

确保恒温器处于加热/冷却模式或冷却模式。确保恒温器未设置为离开。
