The continuously maintained RTR500B Series Help explains model behavior and Bluetooth state, while T&D's complete manual index includes base-unit manuals.
The XML specification confirms T&D's little-endian two-byte temperature and humidity conversion, significant digits, and error marker. It does not publish the manufacturer-advertisement envelope or serial-family mapping. The separate communication specification requires agreeing to T&D's terms and applying directly. Those terms prohibit passing the received specification to another person, so it has not been downloaded or copied into this project.
