Is wireless data collection inside an apartment safe?
Yes – wireless meter reading is technically and health-wise safe. The components of the Minol Connect wireless system meet strict EU standards and transmit at minimal power. Nevertheless, tenants and owners often have doubts about whether wireless meter reading is safe. Here's an overview of the most important facts.
Facts about radio data readout: technology, transmission power and security
How often do the devices transmit?
- Heat cost allocators, water and heat meters: 1x daily (meter reading at 24:00)
- Smoke alarm: twice a month (status message)
- Additional radio telegramsOnly in special events such as a low battery alarm
Comparison of transmission power
- Measuring instruments and detectors: 10 to 25 milliwatts (mW)
(For comparison: DECT phone = up to 250 mW, mobile phone = up to 2.000 mW) - Connect Gateway with LoRaWANmax. 500 mW
(Complies with EU standards and is significantly smaller than a smartphone)
How long will the broadcast actually last?
- Transmission duration per device per day: 1–1,5 seconds
- Per year: approximately 365–550 seconds → less than 10 minutes/year

Why does the distance to the radio matter?
The strength of radio waves decreases exponentially with increasing distance. If the distance to the device doubles, the signal strength drops to a quarter. In practice, this means: the further away, the lower the radiation exposure.
What about data security?
The radio telegrams transmitted via the Minol Connect wireless system are encrypted individually for each device using current technological standards (AES128). Decrypting or intercepting consumption data would therefore require enormous technical effort and expense. The transmitted data is managed and processed in a data center certified according to ISO 27.001.
Conclusion: Wireless technology is safe – for health and data
The wireless data collection is safe . The devices transmit infrequently, with very low power, and comply with all EU directives. There are also no data protection concerns – thanks to modern encryption and certified infrastructure.
