LoggerFlex Halo — Wireless remote display and BLE-to-WiFi gateway

Frequently asked questions

What is in the free tier, and what does Premium Access add?

The free tier covers live monitoring, the full alarm engine, on-device alarms and the most recent 45 days of history, for the life of the device. Premium Access adds unlimited history, scheduled exports, 2,000 API calls a year, and the ability to share a device with new users. Nothing stops recording or alarming without it: you see 45 days instead of the full record, and you cannot invite new people, though anyone already shared on the device keeps their access. Premium is bought per device, not per site and not per user.

What happens if Premium Access lapses?

The device rolls down to the free tier automatically. It keeps recording, keeps alarming and stays on the dashboard; history is trimmed to the last 45 days and no new people can be invited, while anyone already shared keeps access. Premium can be bought again at any time from the My Credit section of My Profile, and the older records become visible again. Two exceptions matter: a cellular device needs its connectivity renewal to stay online at all, and EDGE Lite stops sending alarms entirely without Premium. Subscriptions run to their last valid date and are not refunded.

Can I get a battery-life figure for my exact configuration before I order?

Yes, and it is the right way to specify a fleet. Rated life is a function of your recording interval, sync interval, alarm rate, radio type, signal strength and temperature, so a single headline number tells you little on its own. Send those settings, the environment and the number of monitoring points to your authorized LoggerFlex distributor, or talk to an engineer through the contact form, and you get a recommended configuration with an expected runtime attached. Hardware is configured and quoted per application rather than sold from a list.

How will I be alerted if a reading goes out of range?

LF Cloud dispatches an automated phone call, an SMS and an email at the same time, to an unlimited number of recipients. Alarms cascade down your contact list until someone acknowledges, so an excursion calls your phone day or night. EDGE models with a display also raise a local alarm, an audible buzzer and a visual alert on the screen, so staff on site see it even if nobody is looking at a phone. On cellular units the built-in eSIM keeps alarms going out when your Wi-Fi drops.

Can I send alerts to more than one person?

Yes, to an unlimited number of people. Each recipient needs their own free LoggerFlex account and the device shared with them, because sharing is how someone becomes an alarm recipient. Adding new people requires Premium Access; on the free tier existing shares keep working but you cannot invite more. Each person manages their own phone number and notification preferences under Alarm receivers in My Profile, and email is always on. If someone should see the data but never be paged, share the device with the Silent Viewer role.

Will I get flooded with false alarms every time a door opens?

No. LF Cloud runs a four-level alarm engine. Level 1 is an instant alarm the moment a reading crosses your min or max. Level 2, Persistent Condition, only fires if the reading stays out of range for a number of consecutive readings you set, which filters out door openings and defrost cycles. Level 3 is a Time-Weighted Average for long-term exposure. Level 4 is Trend Drift Detection, comparing against historical baselines to catch slow degradation. You can also set a global alarm trigger delay and require all or any parameters to be out of limits.

Will I know if a device stops reporting or loses power?

Yes. Turn on the No Connection Alarm in the device settings and LF Cloud notifies you when a device has not uploaded within the window you set. A missed scheduled upload also triggers an automatic Missing Upload email, and low-battery and external-power-change alerts are sent by email. EDGE units switch automatically between USB-C and their 4 AA cells, so they keep logging and alarming through a power cut. One caution: at a site with poor coverage an alarm raised while offline makes the device retry repeatedly and drains the battery, so use Battery Saving sync there.

Is there an audit trail of who responded to an alarm?

Yes. Every login, parameter change and alarm acknowledgment is written to a timestamped Activity Log that users cannot edit or delete, the immutable record FDA 21 CFR Part 11 and HACCP corrective-action documentation expect. The log sits on the device attributes page alongside Service History and Maintenance Report. An alarm does not quietly clear itself either: the device stays in active tracking, measuring every minute, until readings actually recover. Readings and alarm acknowledgments export together as a signature-ready PDF, or as CSV, for any date range.
