Bring official NIO readings into Home Assistant
Open Telematics for NIO sends the official EU vehicle-data API into Home Assistant, a home automation server. It exposes battery charge, range, odometer and vehicle state, with optional trip and charging history stored by Home Assistant.
Create a Personal Application in NIO's EU developer console and authorize access to your own car. This is a development integration with live ET5 Touring evidence; data permissions vary and it cannot control the car. A current developer tariff was not verified, so API access should not be described as guaranteed free.
