# esp32-emulator (Go) Status: not implemented yet. Responsibility: - Stand in for real ESP32 hardware during MVP development. - Publish plausible telemetry (temperature/humidity/etc.) to `devices/{device_id}/telemetry` over MQTT on an interval. - Subscribe to `devices/{device_id}/commands` and reply on `devices/{device_id}/ack`, so device-control-service has something real to talk to.
