The Full Fleximodo Order History of DOTSOFT Greece: 8 Orders of NB-IoT Parking Sensors, Permit Cards, and Connectivity From 2023 to 2026

Deployment Snapshot: DOTSOFT's Cumulative Fleximodo Footprint

The Client: DOTSOFT SA, One of Fleximodo's Longest-Running Greek Partners

DOTSOFT SA is a Thessaloniki-based software and ICT company founded in 2004, with roughly 50-56 specialised engineers operating out of Pylaia, a southeastern Thessaloniki suburb at the foot of the Chortiatis mountains. The company runs SmartisCity, a smart-city operating system deployed across 30+ Greek municipalities from Athens to Ioannina, Heraklion, and Trikala — where DOTSOFT inaugurated Greece's first smart city operating centre back in 2015. DOTSOFT's engineering work spans web-GIS, fleet management, environmental monitoring, and — most relevant to this story — the INTEL ANN project, an AI-powered parking platform that uses federated learning to predict parking availability before drivers arrive, often delivered under Horizon Europe co-funded programmes that require multi-year operational commitments.

What makes DOTSOFT one of the most instructive case studies in Fleximodo's customer base is not any single order, but the shape of the relationship across time. Eight tracked orders across roughly 27 months reveal a company that started small, quietly turned out to be running one of the largest Fleximodo fleets in Europe, methodically assembled every layer of the smart-parking technology stack, and ultimately graduated from a Thessaloniki pilot into a breakthrough named-municipality deployment. This article consolidates that full order history — from the first NB-IoT parking sensors placed in Kalamaria in October 2023 through the Propontida municipal rollout in January 2026 — into a single growth story.

2021–2023: A Foundation Nobody Saw Until Later, Then a Public Pilot in Thessaloniki

The DOTSOFT story does not actually start in 2023. A June 2024 OPEX renewal (Order 3, discussed below) would later reveal that DOTSOFT had quietly deployed 150 Fleximodo sensors in August 2021 and 92 more in September 2022 — a 242-sensor foundational fleet that had been feeding DOTSOFT's SmartisCity federated-learning models for years before Fleximodo's first tracked hardware order. That foundational fleet is the reason DOTSOFT should be read as one of Fleximodo's oldest and largest production partners in Greece, not a newcomer.

The first order visible in the tracked record came in October 2023 (Order 1): a Kalamaria-district deployment of Fleximodo's IoT Parking Sensor Standard (NB-IoT, in-ground) together with a managed IoT Hub backend/API. Thessaloniki's dense mixed residential-commercial streets and tree canopy create coverage gaps for camera-based occupancy systems, so DOTSOFT needed reliable in-ground parking sensors to supply the continuous, high-accuracy parking occupancy detection that its INTEL ANN federated-learning model depends on. NB-IoT was the natural connectivity choice — the sensors ride Greece's existing cellular network (commonly via a private APN for segregated, secure device traffic) rather than requiring DOTSOFT to install and maintain LoRaWAN parking sensor gateways across municipal sites. The managed IoT Hub cleanly separated the sensing layer (Fleximodo hardware and backend) from DOTSOFT's own intelligence layer (federated learning and prediction), letting each company focus on what it does best.

Five weeks later, in November 2023 (Order 2), DOTSOFT closed the obvious gap in that first deployment. Sensors alone perform parking occupancy detection — they know a space is occupied, but not by whom. Municipalities running resident-permit and time-limited zones need to verify that the vehicle in a restricted space is actually authorised, and manual enforcement (officers walking routes, checking windshield stickers) is labour-intensive and inconsistent. DOTSOFT's answer was IoT Permit Cards (BLE) — wireless vehicle-identification cards placed in authorised vehicles and read by the same in-ground sensors already installed, paired with IoT Hub OPEX billed annually per card. The result was a complete detection-plus-identification system: sensors answer "is this space occupied?" while Permit Cards answer "is this vehicle allowed to park here?" — a genuine parking enforcement software layer riding on top of the existing hardware, all visible through the Fleximodo CityPortal dashboard. Combined, the two-order Thessaloniki pilot gave DOTSOFT a proven, replicable template it could in principle extend across its 30+ municipal relationships.

2024: The Hidden Fleet Comes to Light, and a 10-Year Connectivity Lock-In

June 2024 (Order 3) looked, on paper, like a routine OPEX renewal. In practice it rewrote DOTSOFT's profile. The renewal referenced five historical invoices dating back to Invoice 029/2021, confirming 150 sensors deployed in August 2021 and a further 92 in September 2022 — 242 confirmed sensors, with several additional unitemised invoices suggesting the true managed fleet was even larger. This meant DOTSOFT's SmartisCity platform had been training its federated-learning models on continuous Fleximodo parking occupancy detection data since 2021, three years before the Kalamaria sensors and Permit Cards that most observers would assume were DOTSOFT's starting point. The renewal itself was structured across multiple multi-year terms — the foundational 150-sensor fleet, for instance, was recommitted through August 2025 — which matters architecturally for a federated-learning system: removing sensors doesn't just shrink coverage, it degrades the model by removing training nodes, so continuity of the fleet under OPEX is what keeps SmartisCity's predictions improving rather than stagnating.

Six months later, December 2024 (Order 4) addressed a different kind of risk entirely: connectivity cost drift. EU-funded and municipal smart-city projects are typically scoped with a multi-year operational horizon, but recurring connectivity costs are often under-budgeted at procurement time, and by year three a project can find SIM fees have crept upward through renewals and operator pricing changes. DOTSOFT's solution was to prepay 10 years of NB-IoT roaming connectivity in a single order, supported by GOSPACE LABS, a connectivity-management partner responsible for SIM lifecycle handling, network troubleshooting, and operator-side escalation. The 10-year horizon was deliberately matched to the hardware replacement cycle — Fleximodo's in-ground sensors carry roughly a 6-year battery rating extendable under favourable conditions, and European NB-IoT operator commitments typically run 10-15 years — so that when sensors eventually need replacing, the connectivity contract renews in parallel rather than becoming a stranded, out-of-sync obligation. It also created a clean three-way division of labour: Fleximodo as hardware vendor, GOSPACE LABS as connectivity specialist, DOTSOFT as platform integrator, each focused on the layer it does best. Connectivity of this type is commonly delivered over a private APN, keeping IoT device traffic segregated from the public internet.

2025: Operational Maturity — Top-Ups, a Replacement, and the First Sensor Standard 2.0

By 2025, DOTSOFT's relationship with Fleximodo had shifted from building the stack to maintaining and evolving it. 16 October 2025 (Order 5) was a small, single-sensor top-up under Fleximodo's NO OPEX pricing model — hardware only, no new backend subscription, because DOTSOFT's existing IoT Hub, OPEX, and connectivity arrangements already covered the addition. It is one of the smallest orders in DOTSOFT's history, but its real significance is what it confirms: two years on, the Thessaloniki deployment is still active and still generating procurement activity.

Six days later, 22 October 2025 (Order 6) was far more consequential: DOTSOFT placed the first order for IoT Parking Sensor Standard 2.0, a next-generation flush-mount NB-IoT parking sensor, anywhere in Fleximodo's invoice record. Hardware platform revisions of this kind typically bundle up years of field-deployment learning — sensor behaviour under climate extremes, battery-degradation patterns, refined detection algorithms — into a new design, and the fact that DOTSOFT received it first is a direct consequence of 24 months of deep platform familiarity. DOTSOFT's Mediterranean deployment environment (high summer heat, coastal salt-air exposure, dense urban traffic) also makes it a genuinely useful field-validation site, exercising different stress conditions than a typical northern European deployment. The order paired the new sensor with customer-provided NB-IoT SIMs (consistent with DOTSOFT managing its own Greek cellular connectivity), DOTA (Delta Over-the-Air) firmware updates bundled with backend monitoring through CityPortal, and a Bronze Card support tier (6 hours) — support that even a veteran integrator benefits from when commissioning workflows change between hardware generations.

17 November 2025 (Order 7) was smaller in scope but notable in wording: the invoice line explicitly read "replacement," one of the rare instances in Fleximodo's dataset where the description states outright that a specific fielded sensor had failed, been damaged, or reached end-of-life and was being swapped for a direct substitute. In any long-running in-ground deployment, replacement is a normal operational event — vehicle impact, resurfacing and utility work near sensors, early-life electronic failure, or battery variance can all trigger it, even on IK10-rated hardware built to withstand the equivalent of a 5 kg steel ball dropped from 40 cm. For a 25-month-old Thessaloniki deployment, an occasional replacement under the NO OPEX model is exactly what a healthy, actively maintained fleet looks like — the replacement sensor drops straight into the existing CityPortal-monitored infrastructure without any new platform purchase.

2026: Propontida — From Steady Top-Ups to a Breakthrough Municipal Order

27 January 2026 (Order 8) broke the pattern entirely. After seven orders of steady, incremental engagement — platform first, detection products second, renewals and connectivity third, operational top-ups and hardware evolution fourth — DOTSOFT placed an order that, on its own, was several times larger than its entire previous order history combined, making it DOTSOFT's largest single order to date by a wide margin. The invoice named, for the first time in DOTSOFT's record, a specific Greek municipal end-client: Propontida (Δήμος Προποντίδας), a municipality of roughly 75,000 residents on the Chalkidiki peninsula southeast of Thessaloniki, whose coastal towns — including Nea Moudania and Nea Kallikratia — face substantial summer tourism-driven parking demand.

The order combined IoT Parking Sensor Standard (NB-IoT, in-ground) hardware with backend and monitoring included, express shipping reflecting a commissioning deadline likely tied to tourist-season preparation, and — for the first time anywhere in Fleximodo's dataset — a Silver Card support tier: 25 hours of first-year support, roughly five times the allocation of a Bronze Card. The Silver Card description explicitly covers "onboarding and training of Propontida city team," confirming this is a direct municipal handover: Propontida's own staff, not DOTSOFT, will operate the deployed sensors day to day, with DOTSOFT serving as the integrator that installs, configures, trains, and then steps back. That handover model — turnkey delivery followed by independent municipal operation — is one of the clearest signals that a smart parking sensor deployment has matured from pilot to production-grade infrastructure. It is also the clearest evidence yet that DOTSOFT's 27 months of platform-building were never really about Thessaloniki alone; they were the credibility base for winning and delivering exactly this kind of named, regional, multi-department municipal project.

Order / Deployment Timeline

Why Did DOTSOFT Greece Keep Ordering From Fleximodo?

Read end to end, the eight orders are not eight unrelated purchases — they are one company systematically assembling, then extending, a complete smart-parking technology stack over more than four years (including the foundational 2021-2022 fleet uncovered in the June 2024 renewal). DOTSOFT started with occupancy detection, added identification and enforcement, confirmed and renewed the platform layer, locked in a decade of connectivity, kept the fleet healthy with top-ups and a replacement, became the first customer trusted with next-generation hardware, and ultimately used all of that accumulated platform familiarity to win and deliver a named municipal project for Propontida. Each order solved a specific, concrete problem — never a wholesale re-platforming — which is precisely the pattern of a customer who trusts the vendor enough to keep building on the same foundation rather than shopping around. For DOTSOFT, staying with Fleximodo meant every new order (a Permit Card, a connectivity plan, a 2.0 sensor) plugged directly into infrastructure and data history that already existed; switching vendors at any point would have meant discarding years of CityPortal deployment history and federated-learning training continuity. That compounding switching cost, paired with steady product evolution on Fleximodo's side (Sensor Standard 2.0, Silver Card, GOSPACE LABS connectivity), is the practical answer to why a repeat customer keeps repeating.

What Is Automatic Temperature Compensation?

Across every generation of DOTSOFT's deployment — the original Sensor Standard, the Permit Cards, and presumably Sensor Standard 2.0 — accuracy depends on a feature called automatic temperature compensation. It is a calibration process built into Fleximodo's magnetometer parking sensor firmware that continuously adjusts the magnetometer's baseline reading as ambient and ground temperature shifts between winter cold and Mediterranean summer heat (Thessaloniki regularly exceeds 40 °C). Without it, that thermal drift in the magnetic field could be misread as a vehicle arriving or leaving; with it, sensors sustain their rated 99.96% detection accuracy year-round, across an operating range of -40 °C to +85 °C, whether the deployment is in Kalamaria in August or in a Propontida winter.

Beyond Sensors: The Wider CityPortal Ecosystem

DOTSOFT's own deployment has centred on in-ground parking sensors, Permit Cards, NB-IoT connectivity, and CityPortal-based monitoring — but the same CityPortal platform that reports its occupancy and identification data also supports Fleximodo's broader smart-city product line, including digital parking signage, driver-facing parking guidance systems, and outdoor beacons for cities that want to extend from pure occupancy detection to active driver guidance. None of those have appeared in DOTSOFT's invoice history to date, but they sit on the same backend and data model DOTSOFT already operates — a natural next layer should a future project (in Thessaloniki, Propontida, or elsewhere in DOTSOFT's 30+ municipal network) call for it.

Frequently Asked Questions

How many sensors does DOTSOFT actually operate through Fleximodo? A June 2024 OPEX renewal confirmed 242 sensors deployed in 2021-2022 alone (150 in August 2021, 92 in September 2022), with several additional unitemised invoices suggesting more. Combined with the 2023-2026 NB-IoT sensors, Permit Cards, top-ups, and the Propontida order, DOTSOFT's total fleet likely exceeds 300 Fleximodo sensors — making it one of the larger AI-driven smart parking sensor deployments on Fleximodo infrastructure in Europe.

Why did DOTSOFT deploy sensors as early as 2021, years before its first tracked hardware order? DOTSOFT's SmartisCity platform needs large-scale, continuous parking occupancy detection data to train its federated-learning models. The 2021 deployment of 150 sensors — and 92 more in 2022 — provided the foundational training dataset behind the AI predictions SmartisCity delivers to Greek municipalities today, well before the Kalamaria sensors and Permit Cards most observers would assume were the starting point.

How do the sensors and Permit Cards work together? Sensors answer "is this space occupied?" — feeding both real-time guidance and DOTSOFT's federated-learning prediction model. Permit Cards, read by the same in-ground sensor via BLE, answer "is this vehicle authorised to park here?" Together they form a single hardware layer supporting both parking guidance and parking enforcement software, with DOTSOFT's AI layered on top.

Why commit to 10 years of NB-IoT connectivity upfront? Smart city deployments fail more often on recurring operational costs than on upfront capital investment. Prepaying a decade of connectivity — with GOSPACE LABS handling SIM lifecycle, troubleshooting, and operator escalation — eliminates the risk of mid-lifecycle price escalation and administrative overhead, and aligns the connectivity horizon with the sensors' hardware replacement cycle.

What is the difference between OPEX, OPEX renewal, and NO OPEX? OPEX is an annual per-sensor platform fee covering backend processing, API access, and monitoring. NO OPEX delivers hardware only, for customers — like DOTSOFT on its top-up and replacement orders — who already have a platform relationship in place and need only the physical sensor. OPEX renewal simply extends an existing managed-service term, as DOTSOFT did across multiple historical invoices in 2024.

Why does an explicit "replacement" designation on an invoice matter? Most orders don't state whether sensors are for expansion or replacement. DOTSOFT's November 2025 invoice explicitly read "replacement," confirming a specific fielded sensor had been removed from service — normal wear from vehicle impact, nearby construction, or component variance — and was being directly substituted, which is itself evidence of an actively maintained, healthy production deployment rather than one in decline.

What is Sensor Standard 2.0, and why did DOTSOFT get it first? Sensor Standard 2.0 is Fleximodo's next-generation flush-mount NB-IoT parking sensor, first deployed anywhere in October 2025 — by DOTSOFT. Two years of deep, full-stack platform familiarity (IoT Hub, Permit Cards, OPEX, connectivity, original Sensor Standard) made DOTSOFT a natural field-validation partner, and its Mediterranean deployment conditions (heat, coastal salt air, dense urban traffic) provided a genuinely useful stress-test environment.

What is the Silver Card support tier, and why did Propontida need it? Silver Card provides 25 hours of first-year support — roughly five times a Bronze Card. It is calibrated for major deployments that require both integrator onboarding and municipal end-client training: multiple sessions for different city department staff, on-site commissioning, and post-deployment troubleshooting during the first operational weeks. Propontida's Silver Card explicitly covers onboarding and training of the city's own team, confirming a turnkey handover to direct municipal operation.

What is automatic temperature compensation in a parking sensor? Automatic temperature compensation is a calibration process built into Fleximodo's magnetometer parking sensors that continuously adjusts the sensor's magnetic-field baseline as ambient and ground temperature swings between seasonal extremes. Without it, thermal drift could be misread as a vehicle arriving or leaving; with it, Fleximodo sensors sustain their 99.96% detection accuracy across a -40 °C to +85 °C range — including Thessaloniki's hot summers and Chalkidiki's tourist-season heat.

Why did DOTSOFT Greece keep ordering from Fleximodo? Because each of the eight orders solved a specific, concrete problem while building directly on infrastructure, data, and platform history that already existed — occupancy detection, then identification, then confirmed fleet renewal, then connectivity certainty, then routine maintenance, then next-generation hardware, then a full municipal handover. Switching vendors at any point would have meant abandoning years of CityPortal deployment history and federated-learning training continuity. That compounding value, combined with Fleximodo's own product evolution (Sensor Standard 2.0, GOSPACE LABS connectivity, the Silver Card tier), is what turned a single Thessaloniki pilot into a four-year, eight-order relationship culminating in DOTSOFT's largest deployment to date.
