Notification groups describe how the messages and alarms will be delivered to users.

There are the following ways:

• Email: the message will be delilvered through the smtp relay server to the user’s email address or to a specific email address
• SMS: the message will be delilvered through the sms proxy server to the user’s phone or to a specific phone number
• Telegram: the message will be delilvered to a specific Telegram user account

The steps to create a Telegram Notification are:

1. Create a channel to Telegram and a bot
2. Configure the channel to NeMo
3. Create the Notification group
4. Testing the notification group

• Fisrt step is to create a channel. Telegram members will join to the channel to read the Telegram nofitication sent by NeMo through the bot (https://telegram.org/faq_channels). For more information about bot please visit https://core.telegram.org/bots

• Second step is to create a bot to add as administrator member of the channel. Open Telegram BotFather and create the bot with the command /start and follow the instruction. Here is an example of a bot creation:

• Third step add the bot to the channel.

• Fourth step is retrieving the chat_id of the channel. With the NeMo shell (or any other linux machine) you need to find the chat_id related to the channel:

curl https://api.telegram.org/bot<ADD the Token here>/getUpdates?offset=0

{"ok":true,"result":[{"update_id":611548852,
"channel_post":{"message_id":2,"chat":{"id":**-1001148557862**,"title":"Channel-test","type":"channel"},"date":1499934011,"text":"/my_ip","entities":[{"type":"bot_command","offset":0,"length":6}]}}]}

In this case the chat id is: -1001148557862

1. On Admim tab, select Configuration/Notification Groups/Telegram Channels
2. Click Add Channel and insert the Name of the channel that will be used on NeMo, the description, the chat identifier and the Bot Token

1. Create a new notification group (Configuration/Notification Groups→Add Group) and save changes
2. Select the notification group and click Edit Group button
3. select the tab Members and select Telegram as method
4. Select the Telegram channel

The administrator of the telegram group must add users that want to receive notification in the group, then select the notification group on NEMO and click Send Test button.

Congratulations, you have created your Telegram Notification group!
