Yes. Tesla’s Powerwall requires an active Internet connection. More specifically, its the Gateway part of the Powerwall system that requires an Internet connection for it to work properly.
You’ll need Internet access to get software updates and get new product features.
You’ll also need an Internet connection for the Tesla mobile app to work and so that you can monitor your energy production and usage.
You’ll need the Internet in 1 of 3 ways:
- A good Wi-Fi connection,
- A wired Ethernet connection,
- or a cellular connection.
However, if you lose Internet connection for a little while, that’s OK. The Powerwall can still operate with its most recent settings.
