Best way to track and inform user of errors or actions

Hi Guys,

Having everything connected to each other using Home Assistant is awesome!
Creating automations, scripts and monitoring things is really nice.

The next step is not too only to keep things running as they should, but also react on errors.

Some examples:

  • Battery levels of zigbee humidity/motion sensors
  • Filter replacement of the mechanical ventilation system
  • A energy monitoring plug is unavailable (power is off, or the wifi connection is bad)

I can’t really find the best approach for home assistant to do this. I do not only want to receive one notification message to my phone as these errors are there, but there should also be an overview of all actions.

Also, it would be great to create some sort of a template to specify which things should be notified.

Does anyone already have something setup like this?
