1. A building system for a building, the system comprising:
an environmental controller comprising a controller radio, wherein the environmental controller is configured to communicate a wake-up message; and
an environmental sensor comprising a sensing element, a wake-up radio, and a main radio, wherein the environmental sensor is configured to:
operate the main radio in a low power state;
receive the wake-up message from the controller radio via the wake-up radio;
operate the main radio in a high power state and cause the sensing element to gather environmental data in response to a reception of the wake-up message via the wake-up radio; and
communicate the environmental data gathered by the sensing element to the controller radio via the main radio in response to the main radio operating in the high power state.
