You do not have to decide by hand who gets each plumbing or lighting issue. Let people follow the tags they look after. They get a notification for every new issue with that tag, or the issue is assigned to them automatically.
Settings is available to admins.
Set it up
Make sure the tags exist. See Add tags to sort your issues.
Go to Settings, then Users, and open the person who fixes these issues.
Under Subscribe to tags, click Select tags, choose their tags and click Select.
To have the issues assigned to them, tick Assign subscribed Issues. This option appears once at least one tag is selected.
Click Save.
What happens
Without Assign subscribed Issues: the person gets a notification for every new issue with one of their tags.
With Assign subscribed Issues: the issue is assigned to them automatically a moment after it is created, so nobody has to assign it by hand. If the issue has no due date, it is due today.
Good to know
It works for every issue that has a tag, whether it is created on the web or reported from the mobile app.
It applies to new issues. It also applies to an open issue when its tags are changed.
The person must have access to the unit group of the room the issue is in.
If several people follow the same tag and have Assign subscribed Issues ticked, the issue is assigned to all of them.
An issue without tags, or with a tag nobody follows, is not assigned automatically.
