 - Time/MAC/strings: `server/utils/datetime_utils.py` (`timeNowDB`), `front/plugins/plugin_helper.py` (`normalize_mac`), `server/helper.py` (sanitizers). Validate MACs before DB writes.
 - DB helpers: prefer `server/db/db_helper.py` functions (e.g., `get_table_json`, device condition helpers) over raw SQL in new paths.

 - When adding a plugin, start from `front/plugins/__template`, implement with `plugin_helper`, define manifest settings, and wire phase via `<PREF>_RUN`. Verify logs in `/tmp/log/plugins/` and data in `api/*.json`.
 - When introducing new config, define it once (core `ccd()` or plugin manifest) and read it via helpers everywhere.
 - When exposing new server functionality, add endpoints in `server/api_server/*` and keep authorization consistent; update UI by reading/writing JSON cache rather than bypassing the pipeline.
+- Always try following the DRY principle, do not re-implement functionality, but re-use existing methods where possible, or refactor to use a common method that is called multiple times
+- If new functionality needs to be added, look at impenting it into existing handlers (e.g. `DeviceInstance` in `server/models/device_instance.py`) or create a new one if it makes sense. Do not access the DB from otehr application layers.
+- Code files shoudln't be longer than 500 lines of code
