Home Assistant alerts that ring, not just buzz

A leak or an open door sends a WhatsApp. Save BreakPass as a favourite, and the urgent ones can ring through Do Not Disturb.

Point a Home Assistant automation at BreakPass’s webhook link or email address. When a sensor trips — a leak, an open door, a smoke alarm — BreakPass sends a WhatsApp message, or calls your phone for anything urgent enough to need a real ring. It works with the sensors and automations you’ve already built.

I found that some were received by my phone instantly, whereas others had a delay of minutes. For critical alerts... this wasn’t acceptable.

How it works

  1. A Home Assistant sensor trips — a leak, an open door, a smoke or water alarm.

  2. Your automation decides how urgent it is: a message, or a call that needs answering.

  3. BreakPass delivers it — WhatsApp for most things, a call that rings through Do Not Disturb for anything urgent, once you’ve saved BreakPass as a favourite.

Tell your agent

Agent brief

When the kitchen or basement leak sensor triggers, or the garage door has been open for more than 20 minutes overnight, WhatsApp me. If a leak sensor triggers while I’m marked away, call me instead.

WhatsApp alert

Alert from Home Assistant: Leak sensor triggered under the kitchen sink. Acknowledge / Snooze 60 min.

Call script

Alert from Home Assistant. Leak sensor triggered under the kitchen sink. Press 1 to acknowledge.

Home Assistant is good at noticing things — a leak, a door left open, a freezer running warm. The gap is what happens next. A push notification is easy to miss if your phone is charging in another room, or set to Do Not Disturb overnight, which is exactly when a leak or an open door matters most.

What to watch

Not every sensor deserves a phone call. A useful split:

  • WhatsApp for things worth knowing soon: a door left open, a freezer temperature drifting, a routine automation check-in.
  • A phone call for things that can’t wait: a leak sensor while you’re away, a smoke or CO alarm, anything that could get worse by morning.

How to set it up

BreakPass doesn’t replace Home Assistant or decide what’s critical — your automations already do that. You just point the automation’s notification at BreakPass instead of, or alongside, a push notification:

  • Add an automation action that calls your BreakPass webhook link, the same way you’d call any other notification service in Home Assistant.
  • For email-only sensors or third-party integrations, send to your BreakPass email address instead.
  • Keep your existing sensors and automations — nothing new to install in the house itself.

Tips

  • Save BreakPass’s number as a favourite (iPhone) or a starred contact (Android) before you need it. Only a phone call can ring through Do Not Disturb, and only once the number is saved that way. A contact card is provided during setup to make this a one-tap step.
  • WhatsApp and SMS follow your phone’s normal notification settings, so they won’t wake you the way a call can — pick the channel to match how urgent the trigger really is.
  • Add a household member as a second recipient for anything that affects the whole home, not just you.
  • Start narrow. A handful of high-value automations (leak, door, smoke) beats alerting on everything Home Assistant can see.

This isn’t a replacement for the sensors themselves, or for Home Assistant’s own logic — it’s the last mile, making sure that when your home notices something, a person does too, even at 2am.

FAQ

Do I need special hardware?

No. Use the sensors you already have, and point your existing Home Assistant automation at BreakPass’s webhook link.

Will it work if my phone is asleep or on silent?

A phone call can ring through Do Not Disturb once you’ve saved BreakPass’s number as a favourite (iPhone) or starred contact (Android). WhatsApp and SMS follow your phone’s normal settings and won’t break through on their own.

Is this a Home Assistant replacement?

No. Home Assistant decides what’s critical — BreakPass makes sure you hear about it.

What’s the exact Do Not Disturb rule?

Your phone rings, even on Do Not Disturb, once our number is a favourite. Setup includes a one-tap contact card so this takes a minute, not an afternoon.

Can it alert more than one person in the household?

Yes. Add any verified household member as a recipient.
