I have the common setup whereby Node-RED gathers data, sends it to InfluxDB, and then plot it on Grafana to visualize the data. I also use Grafana's alerting features to let me know when something is wrong. Their list of supported "Notifiers" is pretty extensive.
I want to use Node-RED to accept those alerts and do other stuff, e.g. turn on a siren or light, send a message over a PA system, etc. I know how to do these in Node-RED. However, I do not want to re-create in Node-RED the dozens of (somewhat complicated) alert rules that are already set up in Grafana. Instead, I am hoping to notify Node-RED to take the message from Slack / Email / Telegram / Line / etc. and do something with it in Node-RED.
Looking at the list of supported notifiers, I am familiar with almost none of them. Which of these plays most nicely with Node-RED? I know we could use, for example, the email in Node, but I am guessing these is something better, and am hoping someone can recommend one or two from this list.
