Designing a finite state machine with states, events and transitions, and coding it table-driven

Required by

• Building a room controller around a table-driven state machine with persistent modes required
• Naming the ways a device's connection fails (access point, DHCP lease, broker restart, weak signal) and how each is noticed required
• Recognizing which embedded-systems skills (non-blocking loops, state machines, NVS, Serial) connected firmware leans on required
• Running several timers and state machines in one loop as a tiny cooperative scheduler required
