- Firmware: energy.c/h tracks relay ON-time and uptime via k_uptime_get, load_watts (default 400W) persistent via Zephyr Settings API - Payload extended from 7 to 15 bytes (backwards compatible): relay ON-time (uint24), uptime (uint24), load in watts (uint16) - New 'w' downlink for load configuration - Fix downlink handler: 'i'/'w' commands now checked before combined packet - Server: g2h_rs_energy_tracking table for lifetime power_consumption_wh, reboot detection via uptime vs real elapsed time - Decoder/encoder and docs updated
