Zabbix approaching Maintenance notification

[xotabu4]

Hi everyone,
I was looking for a solution for such feature:
* sending a notification to some group of users (Zabbix administrators or maintenance impacted users) about approaching Maintenance of the host or group of hosts.

Looking over this forum, github or other sources haven't lead me to any solution for such functionality.

Are there anyone who do have such function/feature added to their Zabbix server setup?

I haven't done what you're asking about, because it's not a feature we need at my site, but I have used the API to schedule maintenance periods. I think what you're asking for could be done, using a script and the maintenance API. If you've done any web-based programming using a JSON RPC interface then you'll have an easy time with the Zabbix API.
