Smart Thermostat Hub Bridging Private and Public Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deploying and managing smart devices in multi-family residential properties is cost-prohibitive and poses security challenges, especially in older properties, due to the need for complex infrastructure and potential tampering by residents, which hinders widespread adoption.
Innovation Solution
A smart thermostat hub with multi-band/multi-radio communication capabilities acts as a hub to control and secure smart devices, utilizing a low-power wide area network (LPWAN) for management and a private/public wireless network bridge to maintain control and security, allowing residents to connect their own devices while preventing unauthorized access or tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Wi-Fi or Internet-accessible network infrastructure is deployed for smart door locks and devices, then convenience and security are improved, but installation and maintenance costs increase significantly
Solution Approach 1:
A property management platform acts as an intermediary between smart devices and residents, providing centralized control and configuration. This mediator handles network management, device provisioning, and security protocols, reducing the complexity burden on both infrastructure and end-users while maintaining convenience features.
2Ease of operation
If smart devices are made accessible to residents for control, then convenience is improved, but security risks and tampering potential increase
Solution Approach 1:
The system implements dynamic access control where resident permissions and device accessibility are not static but can be adjusted in real-time. The property management platform can dynamically grant, revoke, or modify access rights based on operational needs, security events, or user roles, balancing convenience with security flexibility.
Solution Approach 2:
The system incorporates feedback mechanisms where the property management platform continuously monitors device status, access patterns, and security events. This feedback enables automatic responses such as alerting administrators to suspicious activities, adjusting access permissions based on usage patterns, or notifying residents of security events, thereby maintaining security while preserving user convenience.
3Ease of manufacture
If existing infrastructure is utilized for smart device deployment, then installation costs are reduced, but reliability and security may be compromised
Solution Approach 1:
The property management platform is designed as a universal system that can manage multiple types of smart devices (door locks, thermostats, lighting, cameras) through a single unified interface and control mechanism. This multi-functionality allows the system to work across diverse existing infrastructures without requiring device-specific management systems, maintaining reliability through standardized protocols while reducing installation complexity and cost.
4Reliability
If professional installation and maintenance infrastructure is deployed, then security and reliability are improved, but deployment costs become prohibitive for older properties
Solution Approach 1:
The system incorporates self-service capabilities where residents can perform basic device configuration, troubleshooting, and maintenance tasks through the property management platform interface. Automated provisioning, over-the-air firmware updates, and diagnostic tools enable the system to maintain itself with minimal professional intervention, reducing deployment complexity and ongoing maintenance costs while preserving security and reliability through automated quality control.
Data Source
AI summary
Systems and methods for managing smart devices associated with a multi-family residential property are disclosed. Control or management of smart devices may be provided by a smart thermostat hub that includes one or more processors and a memory coupled to the one or more processors. The smart thermostat hub also includes a first communication interface configured to communicatively couple the smart thermostat hub to a low-power, wide area network (LPWAN) communication link and a second communication interface configured to communicatively couple the smart thermostat hub to a wireless network via a wireless communication link. The wireless network is communicatively coupled to a set of one or more smart devices. The one or more processors are configured to initialize a connection between the second communication interface and the property management platform via the second communication interface.
