## Messages to send Mindie
- Monthly test: "Every month on the 1st at 10am remind me to test the smoke alarms"
- Yearly battery change: "Every year on 1 November at 10am remind me to change the smoke detector batteries"
- Replace the unit: "Remind me on 5 March 2030 at 9am to replace the hallway smoke alarm"

A smoke detector battery reminder on WhatsApp is a monthly message to test the alarms and a yearly one to change the batteries. With Mindie, send "every month on the 1st at 10am remind me to test the smoke alarms" and it repeats every month.

Most people only think about smoke alarms when one chirps at 3am. A regular test is the way to know they work before they're needed.

## When to be reminded

- **Monthly,** to press the test button on each alarm.
- **Yearly,** to change batteries in alarms that take them.
- **On the replacement date** printed on the back of each unit.

## Why it gets skipped

- **Alarms are on the ceiling,** out of sight and out of reach.
- **Silence feels like proof they work.** It isn't.
- **The replacement date is years away** and nobody writes it down.

## Habits that help

- **Pick an easy date to remember,** like the 1st of the month or when the clocks change.
- **Keep spare batteries** on your shopping list so a chirp doesn't mean a late-night errand.
- **Note each alarm's date.** Add a note per room with the date on the back.

## How Mindie handles it

Send the test and battery reminders once. Mindie confirms and repeats them, in your timezone. Reply "done" after each test, or "snooze 1 day" if you need a ladder first. Ask for your alarm notes when it's time to replace one.

## What Mindie doesn't do

- **It doesn't monitor alarms** or connect to smart home devices.
- **It isn't a safety service.** Follow your alarm's instructions and local fire safety guidance.
- **It doesn't message anyone else.** Reminders come to your own chat only.

## FAQ

### How often should I test smoke alarms?
Fire services commonly suggest pressing the test button once a month. Follow the guidance on the alarm and from your local fire service.

### When does the alarm itself need replacing?
Many alarms are made to last about 10 years. Check the date printed on the back and set a reminder for it.

### Can Mindie tell if an alarm is beeping?
No. It doesn't connect to alarms or smart home devices. It reminds you to check.

### Can I set this once for the whole house?
Yes. One reminder covers every alarm. Add "test all 4 alarms", so you don't miss any.

### Can I note when I changed the batteries?
Yes. Send a note with the date, and ask for it when you wonder how old the batteries are.
