It seems like the arlo q-cameras doesn't support the new endpoint to which the CustomMode-method is pointing. I've just added a check if the device is an Arlo Q-camera and if so use the "NotifyAndGetResponse" instead of posting directly to the "https://my.arlo.com/hmsweb/users/devices/automation/active"-endpoint
