Lately, I’ve setup Grafana and I love it.
I’d like to use the Alarm functionality for a few things in my HomeAssistant system, but I’d like Grafana to use HomeAssistant’s notification service to send out important notifications.
Is there anybody that has done this?
Hi Timkoers,
I had the same question and did not find an answer in the blog.
I used the following approach:
I created a notification channel in grafana and used the type webhook and the following webhook settings:
URL: https://mydomain.duckdns.org/grafanapost/api/states/input_boolean.alrm_hightemp
http method: POST
I struggled with passing the autharization bearer key in the post.
Because I have a ngnix server and I used that one to extend the header with the key.
I used the following proxy rule in nginx:
location ^~/grafanapost/ {
proxy_pass http://<my_local_ip>:8123;
proxy_method POST;
rewrite ^/grafanapost/(.*)$ /$1 break;
proxy_set_body '{ "state": "on" }';
proxy_set_header content-type "application/json";
proxy_set_header Authorization "Bearer blabla...................................................................." ;
}
It is not the best option, but it allows grafana to trigger a status change of an input_boolean in home assistant.
I would certainly be interested in a simpler solution…
I build a tool exactly for this. You can find it here: https://github.com/pinpox/home-assistant-grafana-relay
It will listen for webhooks from grafana and send you a notification via home-assistant like this
This is great! I’m able to see the notifications on my phone - but they don’t seem to persist in Home Assistant. But I don’t seem to see any historical notifications in HA so it’s probably a different issue than yours. I do seem to get an exit status of 1 when a client timeout happens, though…

Should I review over on your Github? Thanks again!
Looks like grafana added support for MQTT notifications. After configuring that, I created a quick automation to set up persistent notifications and send the alarms to my phone. This script also includes clearing those notifications:
