Notifications

[ItHasU]

Possible solutions :

• e-mail
• sms
• messaging service
  • Telegram
  • Google chat

e-mail requires an smtp. It is harder to get one easy to connect to.
SMS has extra costs.
Messaging services can usually be used with HTTP API. Maybe some are already connected to MQTT.

Telegram seems to be the easier. It's easy to send a message with only one HTTP request.

Being able to send notifications is useless if we cannot trigger anything.
So basically the first step is to be able to trigger events.

Trigger could be:

• Value not in range
• Value outdated

This is relatively easy to implement. Both in term of edition and of testing. This would be a good first step.
