Understanding How the System Works

Discover how LoggerFlex devices manage recording intervals, syncing intervals, and immediate alarms while maximizing battery life.

Think of your device like a smart helper that quietly watches over things - for example, the temperature in a fridge, the humidity in a room, or the pressure in a pipe.

Recording vs. Syncing: The Two Clocks

It has two clocks inside:

  • One clock tells it when to measure (called the Recording Interval, for example, every 10 minutes).
  • The other clock tells it when to send the data to the internet (called the Syncing Interval, for example, once a day).

Most of the time, the device is sleeping to save battery. When the Recording Interval rings, it wakes up, takes a reading, checks if everything is okay, saves the value with a timestamp, and goes back to sleep.

Later, when the Syncing Interval rings, it wakes up again, connects to the internet, and uploads all the saved data from its memory to the cloud.

Offline Capabilities

Your device can keep recording even without internet access. It stores all readings with timestamps in its internal memory and continues working normally until the next time it connects. Once online, it uploads everything automatically.

Immediate and Delayed Alarms

If something goes out of the safe range (like if the temperature gets too hot or too cold), the device checks what you want it to do:

  • Immediate Alarm: It will not wait for the next Syncing Interval - it wakes up right away, sends an alert, and then watches more closely by measuring every minute and uploading every hour. This gives you frequent updates until everything returns to normal.
  • Delayed Alarm: The device will wait for the time you set. If the readings are still out of range after that delay, it will then send the alert.

So, even if your Syncing Interval is long (for example, once a day), you'll still get alarms immediately or after your chosen delay, not once a day. Remember: Syncing Interval does not affect alarm speed. It only controls how often data is uploaded, not when alerts are triggered.

Best Practices for Intervals

It's best not to change the default Recording and Syncing Intervals. They are chosen based on best practices to give you fast response, reliable monitoring, and long battery life. Setting a shorter Syncing Interval won't make alarms arrive faster - it will only use up the battery much quicker.

And remember, no news is good news. If your device ever misses its scheduled upload, the system automatically sends you a "Missing Upload" email, so you'll always know if something isn't right. No matter what, your device keeps measuring on time, warns you about problems, and lets you know before the battery gets low or if it can't connect.

Important Notes

  • Limited Internet Access: If your device doesn't have permanent internet coverage and you only want to use it as a data logger, keep the Syncing Interval on Battery Saving Mode and do not enable alarms. If an alarm is triggered while offline, the device will try repeatedly to sync and send notifications, which can drain the battery quickly.
  • Battery Type Matters: If your device uses 2 x AA batteries, use only Energizer Lithium Ultimate batteries (not any AA, and not any other Energizer type). If your device uses 4 x AA batteries, you can use any alkaline batteries.
  • Using External Power (USB-C): If your device has a USB-C socket and you plug it into power, it will automatically reduce the Syncing Interval to 15 minutes, allowing more frequent updates while powered.
