Z-Wave: a sub-GHz mesh network for smart homes
Z-Wave is a wireless mesh protocol below 1 GHz. Controllers, nodes, routing, S2 security and Long Range.
SCS: the two-wire bus of BTicino MyHOME
SCS is the two-wire bus of BTicino MyHOME for lighting, blinds, heating control and door entry. How devices are addressed and how the system connects to external software.
KNX: an open standard for building automation
KNX is a decentralised building automation system. Transmission media (TP, PL, RF, IP), addresses, topology and configuration with ETS.
RS-485: the physical layer under Modbus RTU and BACnet MS/TP
RS-485 is not a protocol but an electrical standard for a differential serial bus. Termination, topology, cable and the usual causes of an unstable line.
BACnet: the building automation protocol
BACnet describes objects, properties and services for HVAC, lighting and energy in buildings. Objects, BACnet/IP, MS/TP and BACnet/SC.
Modbus RTU and TCP: registers, functions and common mistakes
Modbus is the most widespread industrial protocol. Its data model, functions, RTU versus TCP and the mistakes that most often cost hours.
Matter: a common language for smart home devices
Matter is an application protocol over IP that unites devices from different makers. Transports, commissioning, fabrics and bridges to Zigbee.
Thread: an IPv6 mesh network with no single point of failure
Thread is a self-healing IPv6 mesh network on top of IEEE 802.15.4. Node roles, the border router and the link to Matter.
Zigbee: how the mesh network for smart homes works
Zigbee is a low-power mesh protocol on top of IEEE 802.15.4. Device roles, channels, security and the usual mistakes when building the network.
