Starting August 1, 2025, a subscription will be required to access advanced Netzero features such as automations, dynamic tariffs, utility integrations, and diagnostics. USD pricing is $6.99/month or $69.99/year (a 16% discount). Local pricing will vary by currency and VAT.
Read on to learn why we are introducing subscriptions, how Netzero can save you more than the cost of a subscription, and the future improvements this change will support.
Netzero has been free to use for its first two years. It began as a better Powerwall dashboard with solar estimates and diagnostic insights. Since then, it has grown to include:
This growth has come with increased infrastructure and development costs. All automations run in the cloud, and Tesla now charges for vehicle API access, further increasing operating expenses.
Netzero was designed not just to complement the Tesla app, but to solve problems Tesla left unaddressed:
Greater control over Powerwall behavior: Tesla’s Self-Powered and Time-Based Control modes offer limited flexibility. Netzero lets you adapt to increasingly complex utility rate plans through custom automations, saving on utility bills in the process.
Integration with smarter utility rate plans: Netzero supports dynamic tariffs (e.g. Octopus Energy, Tibber, ComEd, Amber Electric). Users on Intelligent Octopus Go save up to £80/month by charging their Powerwall during low-cost periods.
Smarter EV and battery coordination: Features like Charge on Solar for non-Tesla EVs and prevention of Powerwall discharge during EV charging reduce grid use and lower bills.
Diagnostics that catch expensive issues: Netzero’s diagnostics helped many users secure warranty replacements for degrading Powerwalls, often worth thousands of dollars. Tesla’s app does not expose this data.
Early detection of solar or Powerwall failures: Over 10% of Netzero users have received actionable alerts for issues like complete solar production loss or a non-functional Powerwall.
Subscriptions will help sustain and accelerate Netzero’s development. Our long-term vision—-Intelligent Home Energy Management—-extends beyond solar and batteries to include:
As renewable generation grows and demand from EVs and electric homes increases, utilities will shift to more complex rate structures. Netzero will help you navigate these changes and reduce your energy costs.
We will also continue publishing research based on anonymized Netzero data. Our recent Powerwall Battery Retention analysis is the first of many planned reports.
When do I need to subscribe?
Starting August 1, 2025, subscriptions will be required for advanced features. You will receive an email reminder. To avoid interruption of automations, subscribe before that date. You can subscribe now to support Netzero early.
Note: if you subscribe before July 1, 2025, your subscription will be extended (renewal date delayed) to account for the initial trial period until August 1, 2025; this extension of up to two months will happen within 48 hours of subscribing, and you will get an email confirmation.
You may need to update the app manually from the app store to subscribe, subscriptions are available in versions 2.1.0 and above. To subscribe, go to Settings > Subscription.
New users get a 30-day free trial and will need to subscribe afterward to maintain access to advanced features.
What if I use multiple mobile devices or have several Tesla systems?
Subscriptions are tied to Tesla accounts. One subscription covers all your devices (Android/iOS/web) and up to three energy systems linked to the same Tesla account.
Note: subscriptions can only be activated through the mobile app (iOS or Android). If you primarily use the web app, you will need to log in on a mobile device once to activate the subscription.
Where are subscriptions available?
Subscriptions are currently available in United States, United Kingdom, Australia, Germany, New Zealand, Italy, Canada, Portugal, Netherlands, and Spain. Users in unsupported countries can continue using advanced features for free until support is added.
Note: availability is based on your App Store / Google Play account region, which cannot be changed manually.
Can I cancel at any time?
Yes. Subscriptions are managed via the App Store or Google Play and can be cancelled at any time. Features will remain active until the end of the billing period.
Is there a free version of the app?
Yes. Dashboards, historical charts, solar forecasting, and data export remain free. Only advanced features (automations, dynamic tariffs, utility integrations, and diagnostics) require a subscription.
Why haven’t I received any communication about this yet?
We are rolling out this announcement gradually to test messaging and address common questions. All users will receive an email and in-app notification well before August 1, 2025.
Why not offer a one-time purchase instead of a subscription?
Netzero incurs ongoing costs: cloud infrastructure costs, Tesla API charges, and development and support cost. A subscription model better reflects these continuing expenses.
To reduce payment frequency, consider the annual plan (16% cheaper).
Why would I pay for Netzero when I can use Home Assistant for free?
We’re big supporters of open-source development, and have contributed to the community by helping unlock Powerwall 3 diagnostics access. Home Assistant is a great alternative, however not entirely free – it requires time to set up and configure, some services for accessing the Tesla Fleet API are paid as well, and it runs on a computer that needs to be powered 24/7 for automations to run.
What if I choose not to subscribe?
You’ll still have access to the core features of Netzero, including dashboards, solar forecasts, and data exports. Advanced features like automations, dynamic tariffs, utility integrations, and diagnostics will pause, but they won’t be deleted.
If you decide to subscribe later, everything will pick up right where you left off – your automations will resume automatically and your settings will remain intact.
