Software

Five apps, one core — all on Windows, Linux and Android. TEDAŞ OSF.07.02 included, 60-day free full trial.

TEDAŞ OSF.07.02 — one click

OSF.07.02 is the hourly consumption form Turkish utilities require: a 24-hour × 31-day grid. meteroptic reads the load profile, fills the form automatically and saves it as Excel — manual cell entry becomes history. It can be switched off with one tap for those who do not need it.

From the meter to the cloud — how it works

1. Talk to the meter. Every compatible meter has the infrared optical window defined by IEC 62056-21 (formerly IEC 1107), or an RS-485 / Modbus port. meteroptic optical probes seat on that window with a ring magnet and talk to the meter — wired (USB, RS-485, UART) or wireless (BLE, SPP, Wi-Fi, Thread, Zigbee, Matter). The probe carries the dialogue losslessly and transparently at the physical layer — plain IEC, DLMS/HDLC over mode-E, or TEDAŞ MASS.

2. Carry the field to the centre. Reading a whole site rather than one meter? The EnerMode gateway family steps in: it bridges the RS-485 or optical line to the centre over Ethernet, 4G/2G, Wi-Fi, LoRaWAN or NB-IoT. The flagship EnerMode64 packs eight radios, two RS-485 ports, relays and configurable inputs into one body; from EM-485-GSM to the failover EM-ETH-GSM, there's a variant for every need.

3. Read, report, manage. The rest is software — and we build that too. Our Windows, Linux and Android apps offer IEC + DLMS reading, OBIS browsing, P.01 load profiles, the TEDAŞ OSF.07.02 form and Excel/PDF reporting. At enterprise scale, MASS-compatible head-end integration collects, validates and manages data from probes and gateways.

In short: every layer from the meter to the cloud, from a single source, in one design language. Whatever the meter, whatever the infrastructure — we'll build the solution that fits.

Why meteroptic?

Fully standards-compliant

IEC 62056-21 (IEC 1107) physical layer with transparent DLMS/COSEM pass-through; works with every compliant meter, brand-independent.

LED status language

PWR, TX, RX and RDY — identical indicators on every device. Field diagnostics take seconds.

Field proven

Industrial design, strong magnetic ring and rugged housing; from test bench to pole in any condition.

Frequently Asked Questions

What is an optical probe (optical port)?

A reading head that docks onto the infrared communication window found on meters. The meter stays galvanically isolated while IEC 62056-21 opens a safe serial channel; the probe converts that channel to USB, RS-485, UART, Bluetooth or Wi-Fi.

Which meters does it work with?

All electricity, gas and water meters with an IEC 62056-21 / IEC 1107 compliant optical port — brand and model independent.

Should I choose BLE or SPP?

Pick MO-BLE for a modern mobile app (iOS or recent Android); pick MO-SPP if you have existing software expecting a virtual COM port on a handheld or Windows PC. iOS does not support the SPP profile — which is exactly why both models exist.

Are DLMS and MASS supported?

Yes. The probes operate at the physical layer; after the mode-E switch, DLMS/HDLC frames and TEDAŞ MASS traffic pass through unchanged.

Do I need a driver?

Only MO-USB needs a one-time driver on Windows (see Downloads). Linux ships with it in the kernel. BLE, SPP and Wi-Fi models need no driver at all.

What do your applications do?

Our Windows, Linux and Android apps offer IEC + DLMS reading, an OBIS browser, P.01 load profiles, the TEDAŞ OSF.07.02 form and Excel/PDF reporting; they come with a 60-day free full trial. See the Software page for details.
