Setting a target temperature throwing an error in Nest thermostat - nest-api

Question

Setting target temperature throwing an error like below. I am using php curl to set the temperature. Any help is appreciated.
object(stdClass)#72 (2) {
["cmd"]=>
string(12) "REINIT_STATE"
["pod"]=>
string(5) "rts04"
}
Code:
echo "Setting target temperature...\n";
$success = $nest->setTargetTemperature(150,$device_serial_number);
var_dump($success);

Answer 1

the easy things are:
Make sure the thermostat is in heat/cool mode, or cool mode.
Make sure the thermostat is not set to away.
Can you post the code block you are using to make the call?
