As a long-time user of openHAB, I’ve always been fascinated by the potential of smart home technology to simplify and enhance our daily lives. However, one aspect that has always concerned me is the reliance on battery-powered sensors. While the reliability of these devices has improved significantly over the years, particularly with the advent of ZigBee, the need for frequent maintenance and battery replacements has always been a minor inconvenience.
This led me and my colleagues to explore the concept of battery-free sensors, utilizing passive technologies like RFID for industrial applications. The idea of applying this concept to smart homes is intriguing. Imagine a setup where a single cabled reader device in the center of a room could passively monitor multiple sensors—door/window contacts, temperature readings, or even button presses—without the need for individual batteries or wiring. This would not only reduce maintenance but also make it feasible to deploy sensors in rented properties where extensive cabling isn’t an option.
I’m curious to know if others in the community share this vision. Would such a system be valuable to you? If so, what features would you prioritize? For instance, would you prefer integration with popular protocols like Wi-Fi and MQTT, or would Thread and Matter support be more critical? Additionally, what price range would you consider reasonable for a system that could passively monitor an entire room’s sensors? Options like €200, €500, or €800 come to mind.
I’d love to hear your thoughts and experiences. Has anyone else experimented with or implemented similar solutions? Your insights could be invaluable as we continue to explore this innovative approach to smart home sensing.
