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.

Setup Uli home

• smart water meters (Ista istameter product brochure)
• heating meter (Ista sensonic II product brochure (german))
• smoke detectors (Ista fumonic 3 product brochure)
• raspberry pi with cc1101 to read 868 Mhz radio signals
