Performing automated building control in a building. A method includes identifying a target maximum polling time defining an amount of time in which all building devices in a plurality of devices should be polled. Each of the devices in the plurality of devices is identified. For each device in the plurality of devices, queries are sent to the device. For each device in the plurality of devices, responses are received from the device. Based on the queries and the responses, a functional query frequency range is determined identifying a range of query frequencies at which queries can be made to each device such that each device functions within a predetermined criteria. Based on the target maximum polling time and the functional query frequency ranges, a device polling scheme is identified. The devices in the plurality of devices are polled according to the identified polling scheme.
