Domoticz

Just added a Remotec ZTS-500US+ thermostat to my Domoticz and am having some issues with it. I can set the setpoints through the webpage, but it doesn't work when I try to use curl with json. When I use /json.htm?type=command&param=setsetpoint&idx=&setpoint= I get the response of:
{
"status" : "OK",
"title" : "SetSetpoint"
}

but the setpoint never changes. Can anyone point out what I'm doing wrong?

Finally figured this out. I had turned polling on for the device and once I turned that off things work as expected.
