LF M-Bus Cloud Bridge — M-Bus meter reading bridge to LF Cloud

Frequently asked questions

Do you make anything beyond loggers — meters, gateways, handheld probes?

Yes. The Cellular Water Meter is an ultrasonic meter with its own 4G modem and managed SIM, so there is no gateway and nothing to pair; your distributor links it to your account. The BLOCK WiFi Water Meter reports flow and consumption over your own 2.4 GHz network. MODGATE brings Modbus RTU and TCP equipment registers into LF Cloud, and the LF M-Bus Cloud Bridge reads wired M-Bus utility meters. The CORE probe spot-checks food core temperature, Agrimax reports soil moisture, temperature and conductivity, and LoggerFlex Halo shows live conditions on a round display at the point of use.

Do I need a gateway, hub or bridge?

No. Every EDGE and BLOCK unit reaches LF Cloud on its own — BLOCK and Wi-Fi EDGE models over your existing Wi-Fi, cellular EDGE models over their built-in modem — so there is no proprietary gateway to buy, mount or maintain and no IT project to schedule. The cellular water meter works the same way, with its own 4G modem and managed SIM. EDGE also broadcasts Bluetooth for local viewing, and that is the single exception: a LoggerFlex gateway is needed only to capture BLE data. Logging, alarms and cloud reporting all work without one.

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.
