  "From the help-centre article \"MyStat as a BACnet Server\" (updated 2026-09-18) and its attachment BACnet_Mapping_MyStat__.xlsx.",
  "The sheet has no access column; inputs (AI/BI/MI) are listed read-only and values (AV/BV/MV) writable. The article says read/write access depends on the object and configuration.",
  "Many values are scaled integers: temperatures in 1/10 °F, setpoints as 2 x °F (120-180 = 60.0-90.0 °F).",
  "Relay, analog output and universal input mapping MVs list their options without numbers.",
  "BACnet-written values are kept through reboots and power cycles."
