For a while i’ve been using the wireless shelly button for all kinds of notifications.
Most of the time i like to use it as a kind of alarm/need-help-now button.

The f*ckin’ awesome button i’m talking about (pictured above) is a small (45x45mm 16mm height) button, which can connect to your wifi and send MQTT messages.
It even has a strap thingy to attach it to your keychain,

Four types of messages:

• short press
• 2x short presses
• 3x short presses
• and long press

When using pushover, you can push alarm and messages to your android (even overriding mute/silent if you configure it that way!)

Configuring the button:

Configuring pushover:

My node red config:
