Grenton Alternative: TL;DR
Grenton is a Polish smart-home platform built on physical modules (CLU, Gate Modbus, Gate HTTP, relays, panels) with local "distributed logic". Energy management is one of nine feature areas and is achieved by wiring devices in and programming integrations – it is a smart-home system first, not a HEMS.
Zerofy is a dedicated cloud HEMS: no hardware, no installer visit, native integrations for inverters, batteries, 28 EV brands and 11 heat pump brands, dynamic-tariff optimization with AI Autopilot, and a white-label platform for installers and energy providers.
What Zerofy and Grenton Have in Common
Solar Self-Consumption
Both can route PV surplus to a battery, EV charger, or water heating.
Automation
Both automate devices based on conditions like production, presence, or weather.
Mobile App
Both offer an app for monitoring and remote control.
Where Zerofy Stands Out
| Zerofy | Grenton | |
|---|---|---|
| Product type | Dedicated home energy management system (HEMS) | Smart-home automation system (lighting, blinds, HVAC, alarm, audio) with an energy-management feature area |
| Hardware requirement | None – software-first cloud HEMS | CLU central unit, Gate Modbus / Gate HTTP modules, relays, sensors, panels |
| Installation | Self-setup in minutes after download | Certified installer required; professional wiring and configuration |
| Inverter & battery integration | Native cloud/API integrations for a wide range of brands | Via Modbus or HTTP gateway with custom LUA scripting per device |
| EV brands | 28 brands connected directly + OCPP chargers | Chargers via custom integration; no direct car connectivity |
| Heat pump brands | 11 brands integrated natively | Heat pump via Modbus/relay integration, configured by installer |
| Appliance support | Miele appliances and smart plugs | Relay-switched loads |
| Tariffs | All TOU and dynamic tariffs (G11, G12, G12w) plus net-billing feed-in tariffs (RCE, RCEm) | No native tariff or spot-price optimization; would require custom scripting |
| Prosumer deposit (depozyt prosumencki) | Planned | Not supported |
| Automation | AI Autopilot: forecasts PV, prices, and consumption and optimizes automatically | Rule- and scene-based automation programmed in Grenton Config |
| Analytics | Detailed energy/cost analytics per device + CO₂ analysis | Status and notifications; no dedicated energy/cost analytics |
| Commercial model | End-user licenses suited for PME 2 subsidies, distributed through selected Polish installers | Hardware system priced per project via installer; no public list prices |
| Availability | Many European countries, 6 languages | 30+ countries via installer network; Poland-based |
| White-label | Full-stack cloud white-label platform with installer backend and marketing integrations | Installer/dealer partner program; no white-label HEMS app |
