+### superweatherdaemon ###
+
+Все "станции" (* - готово):
+- старая метео *
+- новая метео *
+- датчик дождя *
+- датчик грозы (молния <=5км -> FORCEOFF=1; молния >=10км - FORCEOFF=0) 
+    поля: LIGTPWR, LIGTDIST, LIGTTIME
+- ИБП в стойке (через минуту после выключения света FORCEOFF=1; через пять минут после включения - FORCEOFF=0)
+    поля: POWERED (0 - внешнее питание комплекса отключено, 1 - включено) 
+- ИК-allsky (как будет готов - получение "процента облачности" и "температуры неба")
+    поля: CLOUDS, SKYTEMP 
+
+В выдаваемую клиентам информацию добавить "стандартное" поле FORCEOFF (если ==1 - парковаться, закрываться и выключаться,
+в т.ч. компьютер).
+
+Только ИБП и датчик грозы влияют на поле FORCEOFF. FORCEOFF автоматом ставит WEATHER=3.
+Флаг FORCEOFF - исключительная прерогатива "супердемона", как и поле WEATHER. Значение флага снимается лишь по устареванию,
+как для прочих полей с проверкой на слишком старые данные. Лишь если снят FORCEOFF, поле WEATHER может начать понижать
+уровень. Сразу со снятием флага FORCEOFF, снижаем уровень WEATHER до 2. Следовательно, запускать наблюдения можно будет
+лишь через 2N секунд (кстати, добавить в конфиг время ожидания понижения уровня погоды) после подачи питания.
+
+??? Добавить "стандартные" поля: LIGTPWR, LIGTDIST, LIGTTIME (например, если гроза еще дальше 5км, писать эти данные 
+в FITS-шапку).
+
+Обязательно логгировать источники повышения и понижения уровня погоды, а также источник установки флага FORCEOFF.
+
+В управляющий UNIX-сокет добавить комады:
+- forceoff - чтобы можно было вручную ставить/снимать флаг
+- weath - вручную сменять уровень погоды
+- mute/unmute плагинов (по номеру из list); если плагин mute, то вся информация от него игнорируется
+- ?
+
+
+
+### Демон общего питания (robometeo) ###
+
+Мониторит FORCEOFF. При ==1 выжидает OFF_T_WAIT секунд, затем начинает проверять все 5 "роботелов": если купол закрыт и не пингуется,
+отключаем питание оборудования и питание купола (кроме первого). Через OFF_T_FORCE секунд после сигнала даже если комп пингуется,
+но купол закрыт, питание отключаем. Интервалы времени - в конфигурационный файл.
+
+Если все отключено, ждет, пока не наступит 0. Потом выжидает еще ON_WAIT секунд, после чего последовательно подает питание 
+на все купола, выжидает ON_FORCE секунд и поочередно включает нагрузку всех ИБП куполов. Проверяет пингуемость компов и 
+пишет в лог, во сколько какой запинговался.
+
+Аналогично с приборами в стойке: после OFF_R_WAIT секунд пинговать roboserv, robonas и robostorage; как не пингуются все - 
+выключать питание стойки. Либо же принудительно отключать после OFF_R_FORCE секунд. При снятии флага выжидаем ON_WAIT секунд,
+затем включаем напряжение стойки и пингуем ее компы, логгируем.
+
+В конфиг-файл: IP-адреса и номера релюшек оборудования телескопов и стойки, например, 
+
+telescopes=Astro-M1, Astro-M2...
+Astro-M1=192.168.70.33:1:-1  # Название из telescopes = IP:номер реле оборудования:номер реле питания или -1
+Astro-M2=192.168.70.35:2:22
+...
+equipment=roboserv,robonas,robostorage
+roboserv=192.168.70.6:11:-1  # аналогично должен вести себя 192.168.70.6:-1:11
+...
+
+(при разборе конфига группировать по номеру реле оборудования и номеру реле питания; не отключать реле питания, пока
+не отключены все компы, кроме выхода таймаута)
+
+
+
+### weather proxy ###
+
+Добавить флаг forceoff. 
+
+
+
+### Clients ###
+
+Все клиентские демоны используют weather_proxy и его библиотеку, чтобы получать из SHM погодные данные.
+Демоны купола, телескопа и монтировки обязаны создавать в /tmp файлы с FITS-шапками (по ним "демон питания" узнает, что
+можно выключать компьютер).
+
+Клиенты реагируют на WEATHER:
+0 - можно работать
+1 - нельзя открываться, но можно продолжать работать
+2 - форсированное закрывание купола, останов телескопа, остальное без изменений
+3 - закрывание всего, парковка телескопа
+
+
+## Демон купола ##
+
+Форсированное закрывание при WEATHER>1 или FORCEOFF=1.
+
+
+## Демон телескопа ##
+
+Форсированное закрывание при WEATHER>2 или FORCEOFF=1.
+
+
+## Демон монтировки ##
+
+Останов при WEATHER=2 или FORCEOFF=1, парковка при WEATHER=3 (в случае FORCEOFF=1 ни в коем случае не парковать).
+
+ДОБАВИТЬ ключ HDRTIME // UNIX-time of last activity   -> в этом ключе содержится sl_dtime() обновления шапки (нужно для
+демона питания, чтобы контролировать, когда отмерла монтировка). 
+
+
+## Демон питания оборудования и компьютера ##
+
+Этот демон запускается из-под рута. Принимает от пользователя команды вклчения-выключения оборудования (сюда же можно
+воткнуть управление плоским полем, пинание монтировки на включение, управление светом). 
+
+При получении FORCEOFF=1, сначала щелкается кнопка отключения монтировки. Далее 
+проверяются DOMFITSHDR (DOMESTAT= closed), TELFITSHDR (TELSTAT = closed) и MOUNTFITSHDR (HDRTIME должен быть минимум 
+на 30 секунд старше текущего времени).
+Если все ОК, то выключается навесное оборудование и монтировка, а следом - и сам компьютер получает сигнал poweroff.
+
+sync(); // Flush disk buffer to prevent data loss
+reboot(RB_POWER_OFF);
+или (правильней?): system("shutdown -P now")

-Weather daemon for several different weather stations
-=====================================================
+# superweatherdaemon Documentation
 
-## Usage:
+## Overview
 
-```
-Usage: weatherdaemon [args]
-    Be careful: command line options have priority over config
-    Where args are:
+**superweatherdaemon** is a weather monitoring daemon designed for astronomical observatories. It
+collects data from multiple heterogeneous weather stations (meteostations) via a plugin
+architecture, computes a unified weather status, and provides control interfaces over TCP and local
+UNIX sockets. The daemon can issue warnings, change weather level, and even trigger a forced
+shutdown of instruments (e.g., close dome) when conditions become dangerous.
 
-  -P, --pidfile=arg    pidfile name (default: /tmp/weatherdaemon.pid)
-  -c, --conffile=arg   configuration file name (consists all or a part of long-named parameters and their values (e.g. plugin=liboldweather.so)
-  -h, --help           show this help
-  -l, --logfile=arg    save logs to file (default: none)
-  -p, --plugin=arg     add this weather plugin (may be a lot of) (can occur multiple times)
-  -v, --verb           logfile verbocity level (each -v increased)
-  --port=arg           network port to connect (default: 12345); hint: use "localhost:port" to make local net socket
-  --sockpath=arg       UNIX socket path (starting from '\0' for anonimous) of command socket
+The project is written in C, uses CMake as its build system, and relies on the
+[usefull_macros](https://github.com/eddyem/snippets_library) library for utilities and socket
+management.
+
+## Dependencies
+
+- **Build tools**: CMake >= 4.0, C compiler with C11 support, `pkg-config`.
+- **Library**: `usefull_macros` >= 0.3.5 (`sl_*` functions for logging, sockets, command-line parsing, etc.).
+- **Optional**: `net-snmp` (for the SNMP UPS plugin).
+
+On Gentoo/Calculate Linux, install the basic build dependencies:
+
+```bash
+emerge dev-build/cmake dev-util/pkgconf
+# usefull_macros must be installed from its own source; follow its documentation.
+# For SNMP support:
+emerge net-analyzer/net-snmp
 ```
 
+## Building and Installation
 
-TODO: brief documentation will be here
+1. Clone or download the source tree.
+2. Create a build directory and run CMake:
+
+   ```bash
+   mkdir build && cd build
+   cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local
+   ```
+
+3. Customise enabled plugins with `-D` options (all are `ON` by default):
+
+   ```bash
+   cmake .. -DDUMMY=OFF -DFDEXAMPLE=OFF -DHYDREON=ON -DBTAMETEO=ON ...
+   ```
+
+   Available plugin options:
+   - `DUMMY`  Dummy weather station for testing.
+   - `FDEXAMPLE`  Example file descriptor plugin.
+   - `HYDREON`  Hydreon RG-11 rain sensor.
+   - `BTAMETEO`  BTA 6-m telescope main meteostation (shared memory).
+   - `REINHARDT`  Old Reinhardt meteostation.
+   - `WXA100`  Vaisala WXA100 ultrasonic station.
+   - `SNMP`  UPS monitoring via SNMP.
+   - `LIGHTNING`  AS3935-based lightning sensor.
+
+4. Building:
+
+   ```bash
+   make
+   su -c "make install"
+   ```
+
+   The main executable `superweatherdaemon` is installed into `bin`; the plugin shared libraries
+   (`lib*.so`) go to the library directory.
+
+## Configuration
+
+The daemon can be configured entirely via command-line options, a configuration file, or both.
+Command-line options take precedence.
+
+### Command-line Options
+
+| Option | Description |
+|--------|-------------|
+| `-h`, `--help` | Show help message and exit. |
+| `-c <file>`, `--conffile <file>` | Use a configuration file. Point non-existant file to get help. |
+| `-l <path>`, `--logfile=<path>` | Write logs to a file (default: none). |
+| `-P <path>`, `--pidfile=<path>` | PID file (default `/tmp/superweatherdaemon.pid`). |
+| `-p <spec>`, `--plugin=<spec>` | Add a weather plugin; can be repeated for different plugins. Format: `path:type:device` (see below). |
+| `--port=<node>` | Network port for clients (default `12345`). Use `localhost:port` for local access only. |
+| `--sockpath=<path>` | UNIX socket path (start with `@` for an abstract socket). |
+| `-T <seconds>`, `--pollt <seconds>` | Max polling interval in seconds (integer). |
+| `-v`, `--verb` | Increase verbosity level (each `-v` adds 1). |
+
+### Plugin Specification
+
+A plugin is a shared library (`.so`) that provides a `sensor_init` function. It is loaded with the
+`--plugin` option.
+
+Format:
+
+```
+--plugin=library:type:parameter
+```
+
+- `library`: path to the shared library, e.g. `libwxa100.so`.
+- `type`: Connection type  `D` for serial device, `U` for UNIX socket, `N` for INET socket.
+- `parameter`: device path and optional speed (`/dev/ttyS0:9600`), UNIX socket name, or `host:port` for INET.
+
+Examples:
+
+```bash
+--plugin=libreinhardt.so:D:/dev/ttyS0
+--plugin=libwxa100.so:D:/dev/pl2303_0
+--plugin=libhydreon.so:D:/dev/ch340_0:1200
+--plugin=libbtameteo.so         (no device, uses shared memory)
+```
+
+Multiple plugins are listed in order of **importance** (first ones are considered primary for
+weather level calculation).
+
+### Configuration File
+
+The configuration file uses a simple `key = value` syntax, with `#` for comments. Example:
+
+```ini
+# network port for clients
+port = 4444
+logfile = /var/log/meteo/superweather.log
+verbose = 2
+sockpath = "@weather"
+pollt = 1
+reinit_delay = 10
+
+# Weather thresholds
+ahtung_delay = 1800  # in seconds
+good_wind = 5.0      # m/s
+bad_wind = 10.0
+terrible_wind = 15.0
+good_humidity = 65.0 # percents
+bad_humidity = 87.0
+terrible_humidity = 94.0
+good_clouds = 2500.0 # for reinhardt sensor in its units
+bad_clouds = 2000.0
+terrible_clouds = 500.0
+clouds_negflag = 1   # 1 means the higher the value the better
+good_sky = -40.0     # sky minus ambient temperature, degC
+bad_sky = -10.0
+terrible_sky = 0.0
+# plugins - most important first
+plugin = libwxa100.so:D:/dev/pl2303_0
+plugin = libhydreon.so:D:/dev/ch340_0:1200
+plugin = libbtameteo.so
+plugin = libreinhardt.so:D:/dev/ttyS0
+```
+
+Run with:
+
+```bash
+superweatherdaemon -c /etc/weather.conf
+```
+
+To run on system start you can use OpenRó `rc.local` mechanism.
+
+## Plugins
+
+Each weather station is implemented as a shared library exporting a single function:
+
+```c
+int sensor_init(sensordata_t *s);
+```
+
+The `sensordata_t` structure contains all required callbacks, data pointers, and private fields.
+See `weathlib.h` for the full definition.
+
+### Plugin Lifecycle
+
+1. **Loading**: The main daemon calls `s = sensor_new(...)` to create `sensordata_t` structure, 
+   opens given library with `dlopen` and calls `sensor_init` on that new `s`.
+2. **Initialisation**:
+   - Set `s->name`, `s->Nvalues`, `s->values` array.
+   - Configure the communication channel (file descriptor) using `getFD(s->path)`.
+   - Create a worker thread that periodically reads sensor data and updates `s->values`.
+     Don't forget to lock `s->valmutex` on any operation with `s->values`.
+3. **Data delivery**: Each time new data is available, call `s->freshdatahandler(s)` 
+   (this is set by the daemon to `dumpsensors`). The main daemon then merges the data into the
+   global weather evaluation.
+4. **Shutdown**: The daemon calls `s->kill(s)`, which must join the thread, close the file
+   descriptor, and free resources. Default `common_kill` handles most of this; plugins can override it.
+   
+If the plugin is disconnected for some reason (for example, the network connection is lost), the
+daemon will try to reconnect every `reinit_delay` seconds.
+
+### Available Plugins
+
+| Library | Sensor | Type |
+|---------|--------|------|
+| `libwsdummy.so` | Dummy station  outputs random walk data around realistic values. | Test / Development |
+| `libfdex.so` | Example of a filedescriptor based plugin. Prompts for commaseparated values. | Example |
+| `libhydreon.so` | Hydreon RG-11 optical rain sensor. | Serial |
+| `libbtameteo.so` | BTA 6-m telescope main meteostation (shared memory). | Shared Memory |
+| `libreinhardt.so` | Old Reinhardt meteostation (serial, `?U` command). | Serial |
+| `libwxa100.so` | Vaisala WXA100 ultrasonic meteostation (serial, `0R0` command). | Serial |
+| `libsnmp.so` | UPS monitor via SNMP (requires net-snmp). | Network |
+| `liblightning.so` | AS3935-based lightning sensor (serial). | Serial |
+
+### Writing a New Plugin
+
+Use the existing plugins as templates. A minimal plugin must:
+
+- Include `weathlib.h`.
+- Define an array of `val_t` describing each measured quantity.
+- Implement `sensor_init`:
+  - Allocate `s->values`, copy the template array.
+  - Set `s->Nvalues`, `s->name`.
+  - Open the device (use `getFD(s->path)` for serial/sockets) and set `s->fdes`.
+    If your plugin don't need file descriptor, you must set `s->fdes` to any non-negative value.
+  - Create a ring buffer if needed (`sl_RB_new`).
+  - Start the worker thread that reads data, updates values inside `pthread_mutex_lock(&s->valmutex)`,
+    and calls `s->freshdatahandler(s)` (outside mutex locked).
+  - Return `TRUE` on success, `FALSE` on failure (call `s->kill(s)` to clean up).
+- The `weathlib.h` provides helper functions: `common_onrefresh`, `common_getval`, `common_kill`.
+
+## Weather Level Calculation
+
+The daemon combines data from all active plugins and continuously evaluates a global **weather
+level**:
+
+- `0`  **GOOD**: observations can start safely.
+- `1`  **BAD**: risky to start, but can continue.
+- `2`  **TERRIBLE**: dome must close, instruments park.
+- `3`  **PROHIBITED**: complete shutdown, power off equipment.
+
+### Criteria
+
+Each weather parameter (wind speed, humidity, clouds, sky temperature, lightning distance,
+precipitation, etc.) has configurable thresholds:
+
+- `good`  below/above this (depending on sign) the condition is good.
+- `bad`  above this the condition is bad.
+- `terrible`  above this the condition is terrible.
+- `prohibited`  (if defined) above this the condition goes directly to PROHIBITED.
+- `negflag`  if `1`, a smaller value is worse (e.g., clouds).
+- `shtdnflag`  if `1`, entering the terrible/prohibited range also sets the **FORCE SHUTDOWN** flag.
+
+### Special Flags
+
+- **FORCE SHUTDOWN**: Some parameters (e.g., lightning within <= 5km, UPS on battery) carry the
+  `IS_FORCEDSHTDN` meaning and have `shtdnflag = 1`. When their value exceeds the terrible threshold,
+  the forced shutdown flag is raised, which immediately sets the weather level to PROHIBITED and is
+  typically used to cut power.
+- **Manual FORBID**: An operator can send a signal (`SIGUSR1`) or a socket command to forbid
+  observations, which also forces PROHIBITED. `SIGUSR2` or a socket command clears forbidden flag.
+
+### Hysteresis
+
+Once a bad/terrible state is reached, the level is not lowered until `ahtung_delay` seconds have
+passed since the last serious event. This prevents rapid toggling.
+
+## Server Commands (Socket API)
+
+The daemon listens on two interfaces:
+
+1. **Network socket** (TCP, default port 12345)  read-only (in meaning they cannot change any 
+   parameters) access for remote clients.
+2. **Local UNIX socket** (abstract or filesystem, default `@weather`)  full control for local applications.
+
+Commands are sent as plain text strings, terminated by a newline.
+
+### Common (read-only) Commands
+
+| Command | Description |
+|---------|-------------|
+| `get` | Return all collected weather data (all stations). |
+| `get=<N>` | Return data from plugin `<N>`. |
+| `list` | List all loaded plugins with their names and value counts. |
+| `time` | Return server UNIX time (float seconds). |
+| `chklevel` | Show the `sense` (importance) level of every collected parameter. |
+| `chklevel=<N>` | Same for a specific plugin. |
+
+### Local-only (read-write) Commands
+
+| Command | Description |
+|---------|-------------|
+| `forbid` | Get current FORBID flag (0/1). |
+| `forbid=<0/1>` | Set/clear manual FORBID. |
+| `forceoff` | Get FORCE SHUTDOWN flag. |
+| `forceoff=<0/1>` | Set/clear it manually. |
+| `weathlevel` | Get current weather level (0-3 for GOOD-PROHIBITED). |
+| `weathlevel=<0..3>` | Force weather level (use with caution). |
+| `setlevel=<plugin>:<param>=<sense>,...` | Change the `sense` field of one or more sensor parameters. Example: `setlevel=1:WIND=3,HUMIDITY=3` disables wind and humidity from station 1. |
+| `mute=<N>` | Stop refreshing data from plugin `<N>` (mute). |
+| `unmute=<N>` | Resume refreshing. |
+| `ismuted=<N>` | Return 1 if muted, 0 otherwise. |
+
+Reply format: each line is a FITS-like `KEY = value / comment` string; commands that set something
+usually echo back the variable and its new value. For `get=<N>` each `KEY` have a suffix in square
+brackets  number of plugin, e.g. `WIND[1]= 10.1 / Wind speed, m/s`.
+
+## Signals
+
+| Signal | Effect |
+|--------|--------|
+| `SIGTERM`, `SIGINT`, `SIGQUIT` | Clean shutdown (removes PID file, kills plugins, destroys sockets). |
+| `SIGHUP` | Ignored. |
+| `SIGUSR1` | Set manual FORBID (weather level == PROHIBITED). |
+| `SIGUSR2` | Clear manual FORBID. |
+| `SIGPIPE` | Logged, used to detect network plugins disconnections. |
+
+## Files

+| File | Purpose |
+|------|---------|
+| `CMakeLists.txt` | Top-level build definition. |
+| `cmdlnopts.c/.h` | Command-line and configuration file parsing. |
