# Weather station
#### The project based on ESP32 module, builds via Arduino IDE.
#### Main features: registration temperature(outdoors, room), humidity(outdoors, room) and atmosphere pressure.
Three screens change in a loop and show current: Temperature(t, C), Humidity(h, %), Atm. pressure(p, mmHg).
Also, for each measure parameter there're additional data: minimum value, average value, maximum value.
All additional values calculated for the current day, and reset at the beginning of a new day (period from 00:00 to 23:59).
Available interaction with telegram bot, which send data message.

#### Display settings:
In order to show some string as a title of display, the feature ```showTitle``` of Display class must be enabled, when you can add string as a parameter to ```setTitle``` method.
```c++
display.showTitle = true;
display.setTitle("your title");
```
By default ```showTitle``` is enabled and display shows current time.
In order to show additional data min, average, max value for each measure parameter, the feature ```showAdditionData``` of Display class must be enabled.
```c++
display.showAdditionData = true;
```
By default ```showAdditionData``` is enabled.
#### Storage settings:
It supports the storage of additional data(min, average, max value for each measure parameter) in case of power failure and restoring data at the next controller boot (in the same day).
In order to be able to save data in non-volatile memory of the controller, it is necessary to format it in SPIFFS file system.
For more detail of using and adjustment SPIFFS look at
[arduino-esp32fs-plugin](https://github.com/me-no-dev/arduino-esp32fs-plugin)
It's not necessary to use storage and format file system. You can skip this just disable storage feature.
```c++
#define USE_STORAGE false
```
This constant is ```true``` by default.
*In case of using storage, several points should be noted:*
The variable ```storageIsAvailable``` will be ```true``` if storage works as expected and there're no errors.
You can specify periodic of data backups in minutes.
```c++
dataManager.setSaveStateFrequency(20);
```
By default it is 10. Value shout be from 0 to 59 (0 - save every loop iteration).
#### Telegram bot settings:
One important option is interaction with telegram bot.
First of all, it's necessary to create telegram bot by the [Bot father](https://core.telegram.org/bots#3-how-do-i-create-a-bot).
Next step - enable network, telegram options and add WiFi network properties:
```c++
// Turn to false if you don't want to use network
#define NETWORK_ENABLED true
// Turn to false if you don't want to use telegram (available only if network enabled)
#define TELEGRAM_ENABLED true
#define SSID "XXXXXX" // your network SSID (name)
#define PASSWORD "YYYYYY" // your network key
```
when add bot token:
```c++
#define BOT_TOKEN "XXXXXXXXX:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" // your Bot Token (Get from Botfather)
```
Now bot is ready.
Start messaging with bot - send any message, bot will respond with last measured data.
Bot also can respond with additional data set (min, average, max value for each measure parameter).
In that case send to bot message, which start with latin letter 'f' or 'F' or with cyrillic letter 'п' or 'П'.
