Implemented by Noah Bergbauer [1]. Two temperature sensors are exposed, along with pressure (current, min, max and target), reservoir volume (total and filled), pump speed and flow. Pump speed and flow values are user provided and allow the Leakshield to optimize its operation. Writing them to the device is subject of future patches.
