Configuring the notify module in Home Assistant Yellow/Supervised Instances

When I started in on setting up Home Assistant Yellow, I realized that mucking around with the files was not going to be recommended, if even reasonable to do. And I got about 90% of where I needed to go with the UI. But then I had to configure notifications for my flood sensors, and hit a roadblock.

My current configuration is as below, but it’s not obvious how to make this happen in HA Yellow (or indeed any supervised instance). I can’t find any UI for doing this, and there’s no obvious way to edit configuration.yaml. Yet this seems like such a foundational piece of functionality that surely there’s a reasonable way to do this. Does anyone have any insights on what I’m supposed to be doing here?

notify:
  - name: XXX
    platform: smtp
    server: XXX
    port: 465
    username: XXX
    password: XXX
    encryption: tls
    timeout: 30
    sender: XXX
    recipient:
      - XXX

So what are you using for flood sensors and what integration if at all is being used? Do the sensor(s) support using smtp to a smtp server?

You can edit configuration.yaml various ways

  1. Install the web terminal & ssh addon. Ssh in and run nano /config/configuration.yaml

  2. Install the studio code server addon and edit from there

  3. Install the file editor addon, ditto.

A friend ended up solving my issue, by recommending installing the File Editor add-on. The SSH add-on also would presumably have worked, but this seemed easier for the modest changes I needed to make.
