Critical functions such as door open detection and indicator outputs will be protected by MQTT's authorisation functions. Non-critical functions (eg temperatures) may be unsecured, but the naming convention for data will indicate trustworthiness. The server will not be exposed outside the internal network except by explicit export of certain data items by another process, or via tunnels etc. maintained elsewhere on the internal network. All data items are expected to be readable. | Critical functions such as door open detection and indicator outputs will be protected by MQTT's authorisation functions.

Data will, as far as possible, have a data quality indication supporting features such as loss of a sensor node, loss of a hardwired connection, out-of-range data etc. | |||
