Introduction

Goal of the project is to do smart home stuff , especially reading smart meter data without having to buy proprietary, expensive, insecure devices from datahungry, privacy-ingorant and profitmaximizing companies. Therefore alternative hardware and open source "smart home"/"IoT" solutions such as [FHEM] [openHAB] or [Homegear] are preferred. Since Uli already has some smart meters installed in his flat from the energy billing company [Ista] who use the TI CC1101 in their metering devices. Reading the emitted radio signals from these (or similar) devices might be the first step to get a data source and therefore an overview of water, electricity and heating consumption in an open source smart home environment.


Hardware

Approach

  • Try to get the CC1101 to send and receive data
    • Ideally mount it on an arduino nano which is then called a CUL (cc1101 USB lite) [DIY manual (german)]
    • Alternatively use an SDR to record and analyze radio signals from smart meters and try to unterstand them
  • Integrate it in a wireless home server such as FHEM
  • Display the data on something like grafana

Status

History

  • soldered some wire to the cc1101 to use it with raspberry pi serial connection similar to [this] and made it send test data which could be seen with Paul's SDR in a waterfall chart
