Saves battery during low-traffic periods. Requires TimeSync.\r\n\r\n- Circuit Breaker — Automatically blocks DIRECT forwarding to neighbours with degraded links (SNR < -10dB). Transitions to half-open after 5 minutes for a test packet. Good SNR closes the breaker. FLOOD traffic is never blocked.\r\n\r\n- Adaptive TX Power — Dynamically adjusts transmit power (5-14 dBm EU) based on average neighbour SNR.
