**What is the brand:**  
Ratio (website: [https://www.ratio-electric.com](https://www.ratio-electric.com))

**What is/are the device(s)/service for type:**  
EV charging station. Specifically the Ratio chargers managed through the official Ratio app (including the Ratio Solar). The app would show charging status and power, and allow starting/stopping a charge.

**What kind of category/signal(s) would the app use:**  
Via the cloud API behind the official Ratio app (AWS Cognito authentication + REST). Optionally also Bluetooth (BLE) for local control without the cloud (the charger uses the Inspiro IPC protocol over BLE).

**Is there an (public) API / documentation / manual(s) or known (other) implementations (like Blogs/Github etc)?**  
Yes. There is an open-source, reverse-engineered Python client and a working Home Assistant integration:

- aioratio (async Python client for the Ratio cloud API, including optional BLE): [Github](https://github.com/aaearon/aioratio)
- Home Assistant integration by the same author: [Github](https://github.com/aaearon/home-assistant-ratio)

The API is not officially documented by Ratio itself; the projects above document the endpoints, the Cognito authentication flow and the data models quite thoroughly in their READMEs.

**Are you willing to loan or donate to a developer?**  
Yes, donate money

**Extra information:**  
There is no Ratio app in the Homey App Store yet. A working prototype build by myself (with Claude and no programming knowledge) already exists, built with the Python Apps SDK + the aioratio library: pairing with a Ratio account, plus capabilities for power, charging state, car connected, charging blocked, grid-operator power reduction (DSO), error/fault alarm, firmware-update available, and (approximated) kWh.
