On Samos (BB7ZJW5MWK2TFJ, v0.11.2), hours with 40–62 connected devices show 0 clients. Separately, the configured 10 s `report_period` is ignored, so radios report every 60 s.\n\n## Cause\n\n- **Timer restarts:** the stats loop rebuilds `sleep.sleep_op(report_period)` on every iteration ([radio.lua#L492-L499](https://github.com/jangala-dev/devicecode-lua/blob/a9691b9e2e6d43bf8631b0ab08bdbbe14fa6674b/src/services/hal/drivers/radio.lua#L492-L499)). Every client join or leave therefore restarts the timer, and with steady client churn the tick rarely fires. v0.10.6 slept to an absolute deadline ([wireless.lua#L609](https://github.com/jangala-dev/devicecode-lua/blob/v0.10.6/src/services/hal/drivers/wireless.lua#L609)).\n- **`report_period` ignored:** `wifi.lua` reads `radio_cfg.report_period or 60` ([wifi.lua#L355](https://github.com/jangala-dev/devicecode-lua/blob/a9691b9e2e6d43bf8631b0ab08bdbbe14fa6674b/src/services/wifi.lua#L355)). `bigbox-v1-cm.json` sets `report_period: 10` at the `wifi.data` level, not per radio.\n\n## Fix\n\n- Keep an absolute next-report deadline and use `sleep_until_op`.\n- Fall back to the service-level `report_period` when a radio doesn't set one.\n","author":{"url":"https://github.com/cpunt","@type":"Person","name":"cpunt"},"datePublished":"2026-10-29T15:03:57Z","url":"https://github.com/jangala-dev/devicecode-lua/issues/352"}
