For lots of reasons, a bunch of us aviation geeks have a Telegram chat room. We got the idea to build a chat bot in Node-RED that we could ask questions of when we are on the go and just want a quick answer about some aircraft or system status.
We also use the bot chat for alerts since it shows up on our smart watches better formatted than our email does (we used to send a lot of aircraft alerts from Node-RED to our emails, but have been moving them to Telegram).
If you don't have a Telegram account, make one.
Make a room/group.
Add to the group BotFather (You can kick him out once you make your bot).
Use him to create your chat bot.
Pay attention to the bot father reply, it will include your API access token. Do not misplace this token.
In Node-RED, add the node node-red-contrib-telegrambot to your palette.
Helpful hints. Only groups can have bots/people/Node-RED. Don't forget to invite your bot to your channel after you make both.
Highlight the code below and import it into your project (I would make a new flow page for it first, don't just add this to your current flow).

This is what the flow roughly looks like:
You can change the help text and adjust the 'select' switch node as you add and remove bot commands. There are hopefully enough examples here to get you started.
I use the chat bot in at least two different rooms. This is possible because most of the commands pick up the room chatID and use it to return the bot reply back to the room it was involked from.
Here is how the chatID is picked up:
var pl = {
content: msg.payload,
message: msg.url,
type : 'photo',
chatId: msg.originalMessage.chat.id,
from: "ADSBEx"
}
msg.payload.options = {disable_web_page_preview : true};
msg.payload = pl;
return msg;
The alerts however I want to ONLY go to the aviation room, so its chat ID is fixed in the payload. Here is how it looks:
msg.payload = {"chatId":"-123456789","type":"message", "content":"Filtered Marine Satcom Message - Aircraft Related: \n \n "
+msg.payload+""}
msg.payload.options = {disable_web_page_preview : true};
return msg;
The way I found my chat room ID is to invite the @RawDataBot to your chat room and it will show your chatID. Once you get that number, kick the bot out, its pretty anoying.
So, just to sumerize all that.... for bot commands, use the original message ID so the bot reply goes back to the room it was asked from, for alerts, hard code the room you want the alert to go to.
Of course all this only applies if you are using the bot in more than one room.
Here is an example command in action:
First, we simply invoke /help and get the bot commands. Then we ask the bot to show us the current lighting map for the USA, then we ask the bot to show us where an aircraft is. (This is one of my favorit commands as it pulls so much together).
If you add any aviation commands to your chat bot, I'd love to hear about them. Check back to this page from time to time, I will add any extra commands (I have some ideas....).
Oh, and if you clean up the TAF report formatting, I would be super appreciative if you shared that flow.
