Indoor and outdoor monitoring
Indoor and outdoor monitoring with IoT sensors
What happens inside depends on what happens outside. Combine indoor sensors with outdoor weather data, compare them in one dashboard and let rules warn you, or even switch equipment, when conditions change.

How it works
Inside and outside in one view.
Measure indoors
Temperature, humidity and air quality in the spaces that matter.
Measure outdoors
Weather stations and outdoor sensors report temperature, wind, rain and more.
Compare
Dashboards and rules put both sides together.
Respond
Alerts, commands or reports follow from the comparison.
What you can monitor
Both sides of the wall.
Indoor climate
Temperature, humidity, CO₂ and VOC in rooms, storage and technical spaces.
Weather stations
Multi-parameter weather stations measure temperature, humidity, wind, rain, pressure and more.
Weather data
Add SMHI weather to a dashboard next to your own measurements.
Outdoor equipment
Temperature and status in outdoor cabinets, pumps and installations.
Surfaces and ground
Surface and ground temperature where frost or moisture matters.
Your own sensors
Use any supported sensor from our catalogue of over 1,000 devices.
Example sensors from our catalogue

What the platform does
From comparison to action.
Compare readings
Use the rule engine to combine indoor and outdoor values in one rule.
Frost and weather alerts
Be warned by e-mail, SMS, Telegram, webhook or MQTT when conditions cross your limits.
Switch equipment
Rules can send downlinks to compatible devices, such as a LoRaWAN relay controller.
Control from the dashboard
Use setpoint and action-button widgets to send commands yourself.
Trends over seasons
Keep the history and compare winter with summer.
Reports
Export results as PDF, Excel or CSV.
Indoor or outdoor sensor?
What to measure where.
| Indoors | Outdoors | |
|---|---|---|
| Typical readings | Temperature, humidity, CO₂, VOC, occupancy | Temperature, humidity, wind, rain, pressure, surface temperature |
| Main goal | Comfort, health and energy use | Warnings, context and control decisions |
| Placement | Rooms, corridors, technical spaces | Façades, roofs, fields, cabinets and poles |

Why combine indoor and outdoor data?
Indoor conditions and energy use depend on the weather. Seeing both together helps you understand cause and effect and react earlier.
Which outdoor measurements are possible?
Temperature, humidity, wind, rain, pressure and surface or ground temperature, using weather stations and outdoor sensors.
Can I show weather data from SMHI?
Yes. A weather widget lets you show SMHI weather next to your own sensor data.
Can a rule use both indoor and outdoor readings?
Yes. The rule engine can combine readings from several devices in one rule.
Can the system switch equipment on and off?
Rules and dashboard widgets can send commands to compatible devices, for example a LoRaWAN relay controller.
Do I need cabling?
No. Wireless, battery-powered sensors can be placed where you need them, indoors and outdoors.
