The Robotic Observatory by HARDWARE.astronomy and Telescope (RObH.aT) Network, is an open hardware project, driven by undergraduate students, to develop the equipment and software necessary for robotizing small observatories. Critical components of the RObH.aT Network include a weather station and all-sky camera. The weather station--developed with low cost devices-- gathers data on current weather conditions, allowing the telescope to observe safely. The all-sky camera identifies cloud cover, characterizes light pollution, and ensures accurate photometric calibration. Here I report on work to develop these tools, including mechanical and electrical design, software, and prototypes. I will discuss current status, future work, and availability of the designs to the community.
