Online alarm clock for 11:19 am
As you watch the clock for the moment to submit your solar generation meter reading, set the alarm for 11:19 am and keep the figures ready. It gives you a clear cue before the morning slips towards 12:00 pm, so you can record the current reading and send it at the intended time rather than relying on repeated clock checks.
Your meter submission depends on hearing the alert, so check where your browser is sending its sound. Wireless headphones can remain connected in a bag or another room without you noticing, leaving the alarm inaudible nearby. Play a quick test sound, confirm the volume, and disconnect unused headphones if necessary. Keep this page active and your computer or phone awake: if the browser is closed or the device sleeps, the alarm cannot sound, and your solar generation reading could miss its scheduled moment.
While you wait for 11:19 am, keep any late-morning food simple enough that it will not distract you from the meter. A glass of water or a quick cuppa can sit beside you, but leave preparing lunch until after the figures have been submitted. That way, kitchen noise and occupied hands are less likely to pull your attention away just as the alarm is due.
Common questions
Do I need to create an account or download anything?
No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.
Can I change the alarm sound?
Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.
What happens once the alarm goes off?
It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.
Is this alarm accurate across daylight saving time?
It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.
