Wall Monitor for Tesla

Wall Monitor for Tesla is an unofficial Chrome extension that connects to Tesla Gen 3 and Universal Wall Connectors to monitor performance and health. It surfaces real-time readings, temperatures, lifetime statistics, and firmware status, giving you visibility beyond what the official app shows.

Features include firmware tracker and alerts, Wi-Fi diagnostics, error codes with descriptions, data export to JSON or CSV, support for multiple Wall Connectors, and the option to monitor charging costs. It runs locally without a Tesla account and works with any EV using a Wall Connector on the same network. Note: some features require a one-time in-app purchase.
