Weave Energy (Submission at Amazon Climatech Accelerator 2025)

Threading All Your Smart Energy Devices

Challenge


Homeowners increasingly adopt solar, batteries, EVs, and smart appliances — yet these systems operate in silos, causing inefficiencies, underutilization, and higher energy costs. Most users lack simple tools to manage these devices intelligently, leading to lost savings, higher emissions, and frustration. As electrification scales globally, this fragmentation threatens energy efficiency and climate goals.


Solution

Weave is a unified software platform that connects and orchestrates solar, storage, EVs, and smart home devices through Amazon Alexa. It empowers homeowners to monitor, automate, and optimize their energy use seamlessly reducing costs, improving energy resilience, and accelerating decarbonization from the comfort of their homes.


Key Features



  • Device-Agnostic Integration: Connects solar panels, batteries, EV chargers, thermostats, and smart appliances across brands.

  • AI-Driven Optimization: Predictive algorithms maximize self-consumption and minimize energy costs.

  • Alexa Voice and App Control: Intuitive control over energy assets via voice commands and the Alexa app.

  • Smart Notifications: Alerts for peak utility rates, battery thresholds, and energy-saving opportunities.

  • Automation Routines: Customizable routines for efficient energy usage during specific times or conditions.





Approach


  • Built on open protocols (MQTT, Modbus, Matter) for broad compatibility.

  • Cloud-native architecture hosted on AWS (Lambda, Firestore, Cognito).

  • Embedded with Amazon Alexa for immediate scalability and user adoption.

  • Subscription-based model with free and premium tiers.

  • Targeted at middle-income homeowners and renters in high electrification growth regions.




Impact


  • Emissions Reduction: Cuts household energy-related carbon emissions by up to 50%.

  • Cost Savings: Reduces energy bills by up to 30%.

  • Scalability: If deployed in 1M homes, Weave can prevent over 1M tons of CO₂e annually — equivalent to removing 215,000 gas cars from roads.

  • Behavioral Change: Makes climate action intuitive with no technical barrier, using everyday tools like Alexa.

  • Grid Benefits: Shifts household demand intelligently, easing grid stress and enabling broader DER integration.
