- select.py: replace Non-functional High/Low options with Sleep (miner-mode 1) and HEM (miner-mode 2) for Antminer S19K Pro firmware FR-1.17. Adds local MiningModeHEM subclass since pyasic has no native mode-2 class. - switch.py: fix wake-from-sleep for S19K Pro; store and restore mining mode (Normal/HEM) across sleep cycles and HA restarts using send_config() with fallback to resume_mining(). - coordinator.py, config_flow.py, patch.py, etc.: lazy imports and other changes for Python 3.12 compatibility required by HA 2026.3.x. Tested on: Antminer S19K Pro 120TH/s (firmware FR-1.17(250624-S19kPro)), Bitaxe Gamma (BM1370), Home Assistant OS 17.1 / Core 2026.3.2. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Summary
Tested on: Antminer S19K Pro 120TH/s (firmware FR-1.17(250624-S19kPro)), Bitaxe Gamma (BM1370), Home Assistant OS 17.1 / Core 2026.3.2.
Problem
The
activeswitch could put the S19K Pro into sleep mode but could not wake it back up. The S19K Pro has three power states (Sleep / Normal / HEM), soresume_mining()is not sufficient. The power mode dropdown also offeredHighandLowoptions that do not map to valid firmware modes.Changes
select.py: Replaced
[Normal, High, Low]with[Normal, Sleep, HEM]. Sleep usesMiningModeSleep(miner-mode 1). HEM uses a localMiningModeHEMsubclass (miner-mode 2) since pyasic has no native class for this;MiningModeHPMincorrectly sends miner-mode 0.switch.py: Capture and persist active mining mode across HA restarts. Wake miner via
send_config()with stored mode instead ofresume_mining(). Fallback toresume_mining()whensend_config()fails. Preserve stored mode across failed stop attempts.coordinator.py, config_flow.py, patch.py, etc.: Lazy imports for Python 3.12 compatibility (HA 2026.3.x).
Test plan
wow....Claude code did this. Couldn't have done it better!
