Telegram and Email Alerts

General
1

Thanks to the awesome work by @Steve-Mcl I've managed to get my Telegram alerts running. Thanks Steve.

I am now attempting to add email alerting to the same flow... only, I cannot get the Subject to work? Node Red seems to be happy with the flow, but only shows the code in the subject and not the value?

Here's my code...

I also want to add a time stamp to the email... I usually use +time but not sure where to add it?

Appreciate any advice. Thanks, Mark

This should do it for you -

object
type: "message"
content: "Ping to 'Server 5' (192.168.4.14) failed"
chatId: 5612125043
topic: "20/09/2022, 00:36:27 WARNING!! 'Server 5' Server DOWN"

If you want the timestamp in the message instead then just move the ${dateTime} into the msg.payload.content

Are you using the core email node node-red-node-email?

The help for that node says

Sends the msg.payload as an email, with a subject of msg.topic.

But you seem to be using msg.payload.content and msg.payload.topic?

msg.payload.content = `Ping to '${msg.ping.name}' (${msg.ping.host}) failed`;
msg.payload.topic = `${dateTime} WARNING!! '${msg.ping.name}' Server DOWN`;

Hi @jbudd you are absolutely correct... excellent spot! Based on the issue you've highlighted I am thinking I need to somehow take the msg.payload.content and redirect it to msg.payload for the core email node? I figure I could use a change node? Or is there a programmatic approach I could use?

I also need to strip out the msg.payload.chatId as that isn't needed for the email, only the Telegram bot.

Thanks @smcgann99 that code is excellent and pointed me in the right direction. Thank you so much, really appreciate the help :+1:

Change function node as follows to set correct payload and remove "un-wanted" data -

const timestamp = Date.now()
const dateTime = new Date(timestamp).toLocaleString()
msg.payload = `Ping to '${msg.ping.name}' (${msg.ping.host}) failed`;
msg.topic = `${dateTime} WARNING!! '${msg.ping.name}' Server DOWN`;
delete msg.ping
delete msg.payload.chatId
return msg;

object
payload: "Ping to 'Server 5' (192.168.4.14) failed"
topic: "20/09/2022, 02:31:59 WARNING!! 'Server 5' Server DOWN"
_msgid: "d1262ac07cdcddcb"

Hi @smcgann99 tried the code... however it doesn't show the msg.topic for some reason? This is the result...

Ping to 'APOLLO' (192.168.0.14) failed

If I change msg.payload to msg.payload.content then this is the result...

{"type":"message","content":"Ping to 'APOLLO' (192.168.0.14) failed"}

So not sure why the...

msg.topic = `${dateTime} WARNING!! '${msg.ping.name}' Server DOWN`;

Is not showing?

This code appears to work...

const timestamp = Date.now()
const dateTime = new Date(timestamp).toLocaleString()

msg.payload.content = `${dateTime} Ping to '${msg.ping.name}' (${msg.ping.host}) failed`;
msg.payload.topic = `WARNING!! '${msg.ping.name}' Server DOWN`;
delete msg.payload.chatId
delete msg.payload.type
return msg;

Here's what comes out...

9/20/2022, 1:05:51 PM Ping to 'APOLLO' (192.168.0.14) failed
WARNING!! 'APOLLO' Server DOWN

But if I change msg.payload.content to msg.payload it only shows...

9/20/2022, 1:04:42 PM Ping to 'APOLLO' (192.168.0.14) failed

20/09/2022, 08:19:30node: to Email node

It works for me - try the full flow with debug set to complete msg.object
