I saved your requirements in Environmental Node Requirements, including Wi-Fi + BLE, digital temperature/humidity sensing, and protected USB-C 5 V power for 0.5–3 A sources.
The project still has no components or wiring; part selection, power budgeting, schematic design, and verification remain undone and require Agent mode. Execution stopped because your ACUs ran out.
What is Agent mode?
Agent mode lets Flux build, do deep research, validate designs, and work through complex assignments.
Chat mode is just as smart and has the same engineering knowledge, but it cannot work autonomously.
Only Agent mode consumes your plan's included AI usage (measured in ACUs).
