About this app

Increase savings with Powerwall automation and dynamic tariff support, track the health of your Powerwall, and catch solar production issues early. Advanced features require a subscription after a 30-day free trial.

- Integrate with Octopus Energy, Tibber, Amber Electric, or Commonwealth Edison (ComEd Hourly Pricing) for dynamic tariffs (day-ahead utility rate plans). Automatically adjust to the latest tariffs and reduce your electricity bills while supporting grid stability.
- Get automated notifications when there are issues with your solar production or battery health. Track Powerwall capacity and degradation to ensure it remains within warranty limits.
- Get precise estimates for daily, monthly, and yearly solar production and diagnose production issues early.

- Better data downloads, string-level data and other diagnostics, weather data, developer access, and a steady stream of new features.

Ratings and reviews

Having at least a months worth of data to be able to be optionally stored and synced on device would be very handy as the lag to retrieve data online every time is a bore. There should be a setting that allows you to decide how much data to keep locally. The rest of the app seems to work OK. Appreciate the basics though.

Great app doing what it's supposed to do. However the upcoming subscription cost will make it useless in my case. With just one automation the subscription cost will be higher than the savings from the automation. I understand that there are ongoing costs for Netzero but I am afraid the subscription will not be good value for many. Maybe a tiered pricing plan could work but in the absence of it you are better off looking/hoping for an alternative app.

This app is great. The automations are fantastic as they allow me to better control my car charging under more specific conditions and provides notifications at certain thresholds that I set. Also it provides much flexibility in how I utilise my home battery or grid during differing weather conditions and usage patterns.
