Review summary

Netzero for Powerwall is praised as a powerful, user-friendly automation and energy-management tool that extends the Tesla app. It helps maximize savings across multiple Powerwalls and EV charging with insightful data. Common drawbacks include subscription pricing, inaccurate solar production estimates, and missing features some users want (real-time bills, solar string data, more rate integrations). Overall, it’s a valuable ROI-positive app with room for feature improvements.

Pros

Powerful automation and fine-grained control to optimize Powerwall usage (time-based modes, export/charge logic, top-off windows).
User-friendly interface and ease of use, especially on iPad, making Netzero a better companion to the Tesla app.
Helps maximize savings by managing multiple Powerwalls and EV charging, with rate-based optimization and useful data insights.
Provides valuable data, monitoring, and diagnostics that help with decision-making and troubleshooting, even during outages.

Cons

Subscription pricing is a frequent point of contention; several reviewers dislike ongoing fees and would prefer a single upfront price.
Solar production estimates are often inaccurate or overly optimistic compared with actual output.
Users want additional features and data (real-time energy bills, solar string data, broader rate integrations) that are not yet available.

2026-06-07	Bl*****	I really like the app…. That said it’s gone wonky lately. It is displaying the wrong dates info. Today’s data displays yesterday, until it suddenly flips to today’s at random intervals. Then when I swipe to yesterday it shows some previous days data. I have to go to monthly chart to get the correct day totals. Very frustrating.

It incorporates my time of use pricing schedule. I signed up for the year after using it for a week. This is one of those apps that Just Works!

2026-04-15	Ma*****	I really love this app. The free version gives you so much in a nice and clean interface, especially on the iPad — the Tesla app is just so cumbersome. I was so glad to have found this app. I haven’t explored the automations but I subscribed in order to start doing so soon. Recommend 100%.
