# Aliste Technologies > Aliste Technologies builds smart prepaid sub-metering hardware for rental properties, PGs and coliving spaces, and a subscription-based home automation platform for controlling existing appliances via app, Alexa or Google Home. Aliste's smart sub-meters let property owners bill tenants for individual-room or common-area electricity usage automatically: tenants recharge a prepaid wallet via an in-app QR code, and owners get real-time usage dashboards without any upfront hardware cost. Aliste also offers postpaid smart metering, a smart home automation subscription (from ₹2/day) that adds WiFi control to existing appliances, and smart locks. Postpaid metering and smart locks are real, major Aliste product lines that do not yet have dedicated pages on this website — contact Aliste directly for details on either. ## Products - [Smart Prepaid Sub-Meters](https://www.alistetechnologies.com/): Prepaid electricity sub-metering for PGs, coliving and rental properties — zero upfront cost, tenant app-based recharge, owner usage dashboard. - [Buy Smart Meters & Sub-Meters](https://www.alistetechnologies.com/qsr): Purchase smart/sub meters for individual rooms, common kitchens, washing machine areas and AC/geyser circuits — zero upfront cost, lifelong hardware guarantee, 24/7 support. - Postpaid Smart Meters: Smart metering billed in arrears rather than prepaid recharge.
