Observe local heat
Road surface, weather and traffic data help put a local intervention into context.
Lesson: Document measurement conditions. Three days do not yet demonstrate lasting cooling.

Experience from a real village.
Smart Village applications are possible even in small villages. Martinfeld offers practical examples in energy, the environment and traffic – with public measurements, experience and open questions.
Three insights from Martinfeld
Solar power in the village
Photovoltaics on the fire station since December 2024; the sports clubhouse and mayor's office followed in 2025.
Lesson: Clearly distinguish generation, consumption and the local net grid balance.
Example and sources →Making traffic visible
Cameras and radar record traffic. Public time series make observations accessible.
Lesson: Take the measurement site, period and recorded traffic types into account in every analysis.
Example and sources →The benefit determines the sensors, network and platform.
A limited trial makes impact and effort visible.
Maintenance, data upkeep and responsibilities belong in the plan.
7 STEPS
An approach that others can use.
These steps provide a working framework. Depending on the project, they may overlap or be repeated.
01 · Clarify the task
Start with a specific problem and involve those affected early.
- Document the starting point
- Identify the target group and benefits
- Define a measurable target
02 · Build the team
Clearly assign responsibilities across administration, operations and technology.
- Appoint a project lead
- Involve municipal works and specialist departments
- Engage local partners and volunteers
03 · Check the infrastructure
Record existing networks, sites, power supplies and data access.
- Check radio coverage and mounting sites
- Clarify interfaces and control over data
- Identify all ongoing costs
04 · Keep the pilot focused
Test a manageable use case within a defined timeframe.
- Choose a small number of sites
- Secure a baseline before the project starts
- Define stop and success criteria
05 · Measure the impact
Combine technical data with effort, costs and practical benefits.
- Make data gaps visible
- Document changes in operation
- Publish results in an understandable way
06 · Secure long-term operation
Establish lasting arrangements for maintenance, privacy, responsibilities and funding.
- Plan for faults and spare parts
- Document roles and access rights
- Include recurring costs in the budget
07 · Apply elsewhere and expand
Expand to other sites or tasks only after evaluating the results.
- Record findings openly
- Use standards and reusable components
- Reassess priorities for the next phase
PROJECT ROLES
Who needs to be involved?
Administration
Objectives, budget, procurement, privacy and political decisions.
Operations
Municipal works, building management or utilities with day-to-day experience.
Technology partners
Network planning, devices, platform, interfaces and documentation.
Local people
Users, clubs and initiatives who understand needs and acceptance.
Use cases to learn from.
When the road sweats.
How can existing sensors help monitor a local intervention? The Flinsberger Straße case combines road surface, weather and traffic data.
Three hot days in Martinfeld →What can other places learn from Martinfeld?
Lighting: plan for operation
Starting point: The switch to LEDs and networked control was an early part of SMARTinfeld. Feedback from the trial installation and adjusted switching times form part of the project description.
Task for other municipalities: Before a pilot, clarify who maintains switching times, handles faults and receives local feedback. Record energy demand and maintenance effort before and after the change under comparable conditions.
Limitation: The new website does not yet show live consumption or verified savings for this project. The model calculation does not replace that evidence.
Project description and model calculation →Water: interpreting measurements correctly
Starting point: An ultrasonic sensor on the Rosoppe and soil moisture measurements at two trees provide different local observations.
Task for other municipalities: Document the measurement location, reference point and installation depth. A responsible person identifies who checks data gaps and arranges an on-site observation when readings are unusual.
Limitation: Measurements from different depths are not directly comparable. A local water-level reading does not replace an official flood warning.
Measurement sites and context →Confirmed investment costs, operating hours and quantitative before-and-after results are not yet available here for these examples. They are therefore not estimated.

Is your pilot ready to start?
Use this checklist to prepare for your project discussion. Ticks apply only to the open page and are not saved.
Three questions to start a project.
Take a realistic view of costs.
Beyond devices, costs include planning, installation, connectivity, platforms, maintenance, replacement and staff time for analysis and communication. Grants can make it easier to get started; long-term operation needs its own funding basis.
