Fix: AC Control Regression (#636)
Reverts command infrastructure changes from PR #618 that broke AC units (DR-HAC006S, DR-HAC008S, and potentially other AC models).
Changes
- ACK timeout: Reverted from 8s back to 2s (original v1.7.8 value). The 8s timeout caused AC commands to block for up to 24s when no acknowledgment was received, starving Home Assistant's executor threads and greying out AC controls.
- WebSocket reconnect delay: Restored 5s backoff between reconnection attempts on failure, preventing tight retry loops.
- Auto-reconnect handling: Restored proper early-exit behavior matching v1.7.8.
Background
PR #618 (@cash83) added DR-HHM001S humidifier support and modified shared command infrastructure. The ACK timeout increase was intended to help slower humidifier devices but had unintended side effects on AC units. This release reverts the infrastructure changes while keeping all humidifier feature additions intact.
If you were affected by AC controls being greyed out on v1.7.11 or v1.8.0, please update to this version.
