This disclosure relates generally to valves, and more particularly, to gas valve assemblies. In one example, the valve assembly may include a valve body with an inlet port, an outlet port, and a fluid path extending between the inlet and outlet ports, one or more valves situated about the fluid path, one or more valve actuators for selectively moving respective valves, one or more sensors for sensing one or more parameters within the fluid path, and a controller secured relative to the valve body and in communication with the one or more sensors for determining one or more valve assembly conditions based on the one or more sensed parameters. Illustratively, the controller may be configured to communicate information from the valve assembly to a combustion appliance controller that is located remotely from the valve assembly through a communications interface of the controller and across a communications bus.
