Home Assistant was pinned to k8s-edge solely for the USB power meter it
read via edl21. edl21 is now replaced by the sml2mqtt bridge (publishes to
Mosquitto), so HA:
- drops nodeSelector zone=edge + the workload-class=pinned toleration →
the heavy 8Gi pod schedules on the general cluster pool, off the
soon-to-be-tiny edge box;
- drops the /dev/stromzaehler USB hostPath mount + volume (bridge owns the
device now);
- drops securityContext.privileged — the USB device was its only
justification.
This also frees the serial fd the running HA process still held after
edl21's removal (HA recreates without the device), giving the sml2mqtt
bridge exclusive access to the meter.
Meter data in HA resumes once the MQTT sensors (reusing the old
sensor.smart_meter_* entity_ids for history continuity) land in the
homeassistant repo — brief expected gap.
