Engineering challenges
We build the gateway OS, protocol middleware, OTA and fleet tooling, and the companion app, so your team can focus on energy algorithms and partnerships.
Integrating many device protocols and vendor APIs
Every inverter, battery, heat pump and charger brand speaks differently.
Real-time control with unreliable home networks
Control loops have to stay correct even when home Wi-Fi or internet fails.
Secure remote access and frequent updates for grid programs
Grid programs change often, and devices must update safely and securely.
Low BOM cost at consumer volumes
Consumer pricing leaves little room for expensive hardware.
Services for this industry
Production-grade embedded Linux for connected devices: from board bring-up to a maintained, updatable OS image.
Reliable device connectivity and the middleware that ties sensors, protocols and the cloud together.
Over-the-air updates that never brick a device: A/B partitions, signed images, rollback and staged rollouts.
iOS and Android apps that onboard, control and update devices, built together with the firmware and cloud.
Lower your bill of materials without hurting reliability or features.
