Canique Smartmeter Sense - Wireless battery powered smart meter interface

Canique Smartmeter Sense is a battery-operated device that can read the consumption data from your smart meter via an infrared reading head. The consumption data is then transmitted wirelessly to a base station. You can view the data in any browser or integrate the MQTT data into another system.
You need a base station (Pico Gateway or Raspberry Pi HAT) as well as an infrared adapter to operate this device.

Quick Facts:

15 seconds measuring/sending interval (default)
5 years battery life with a single AA size battery
No power connection required near your smart meter
868 MHz radio: better range than WiFi
Transmission of current consumption (watts), total consumption (watt hours), current feed-in (watts), total feed-in (watt hours)

Possible use cases:

Identify power-hungry consumers in your household
Conditionally charging an electric car, batteries, etc. to achieve zero feed-in with a solar system
Determine whether a flat is in active use
Create daily billing of electricity consumption
Billing/measuring the feed-in from a solar power system

Supported smart meters

Currently, as of August 2024, Canique Smartmeter Sense can decode and decrypt data from 3 Smartmeter models.

ISKRAEMECO AM550
SIEMENS IM350
Landis+Gyr E450

If you have a different smart meter, please make an enquiry. To support other smart meters, we need test data from the smart meter.

Cryptographique: 256 Bit Security

Canique Smartmeter Sense encrypts data with a symmetric 256 bit AEAD cipher before sending it. The cipher used is state of the art: Chacha20-Poly1305. This way you can always be sure that the data has not been tampered with, is authentic and has not been decrypted by some other party. Furthermore there are countermeasures implemented against replay attacks.

Automatique: Automatic Gain Control

Canique Smartmeter Sense adjusts its transmission power automatically depending on the distance to the base station.
Every transmitted sensor information is acknowledged by the base station, and if necessary re-transmitted by Canique Smartmeter Sense.

Battery status monitoring

Battery status is measured with 1mV resolution every hour. You know when the battery voltage gets critical even before the battery knows it.
