I built a Homey app for the Ratio Electric EV chargers.
What the app does
Pair with your Ratio app email and password, then see from Homey:
- Charging power, status and mode
- Which vehicle is connected
- Energy charged today and in total*
- Firmware information
- Errors
- WiFi/Ethernet connectivity
* The charger itself doesn’t keep a running kWh counter, so the “charged today” and “total” values are estimated from power readings, and can be slightly inaccurate after a brief interruption in the connection to Ratio’s cloud.
From Homey (or through Flows) you can start or stop charging, change the charging mode, and optionally set a maximum charging current (Basic mode only). Flow cards let you read or set the charging mode, assign a specific vehicle to your charge, and react to charging being blocked, your power being reduced by the grid operator, or a firmware update becoming available. There is also a dashboard widget that shows charging status at a glance.
Still in testing
The app is currently in the Test channel, not yet live in the App Store. Want to help test? Install it through:
