### 5/5 — It does everything I need it to do

*2026-08-12*

This app just keeps getting better and better with every update, it now allows you to export directly from your Powerwall to the grid which also prioritises exporting solar to the grid, so that enables you to keep your Powerwall below 80% and send your maximum export to the grid (which in my case is 5kW) and then any excess charges the Powerwall. 
This will stop any clipping of solar production, which is lost energy and money in your pocket. 
To do this with the Tesla app you have to rely on their algorithm to do this when it is in saving mode, this rarely happens and you have no control.
Have been using this app for just over a year and I can honestly say that I am not disappointed with the results I am getting.
Everything I need is here to optimise my system and get the best returns from exports and control of how I want my system to work, yes it costs but you get what you pay for and if it was free you would be the product.
Thank you Netzero please keep up the excellent service.
This is the only time I have ever left a review on anything, that how impressed I am.

**Developer response:** Thanks for the review!

### 5/5 — Great control and management of powerwall

*2026-08-11, version 2.6.2*

I can’t believe Tesla has not brought this app to integrate into their system.  The app allows you to program your powerwall to make the best of savings and self power. It does it all automatically once you have your programs set. Easy to use and allows far greater monitoring of your solar system. I have 3 strings of panels and Netzero allows me to monitor them individually where as the Tesla app only shows a total output. I use both apps to monitor the system but Netzero gives a lot more control and information. Worth the subscription.

### 5/5 — Excellent

*2026-08-08, version 2.6.2*

Now with the evolving “export to grid” - just what I wanted!
Extremely well thought out
Beautiful interface
Responsive even to my dumb questions 
Now if I could only add in my thermal battery just as it integrates an EV on excess solar only….

### 5/5 — Fantastic monitoring desktop/ipad app

*2026-08-08, version 2.6.2*

Love the ability to view the dashboard on web and tablet - wish there were widgets integration to show on my iPad lock screen and put it on the wall too!

### 5/5 — Recommended

*2026-08-08, version 2.6.2*

Subscribed after nightmare of trying to use Home Automation. Unlike ha this works and is easy. Scuse me while I now go shoot the ha box in the garden.

### 1/5 — RHC

*2026-08-08, version 2.6.2*

App w / latest download shows solar output 4.7kw at noon no clouds  compared  to estimate has also changed the whole history. Sorry app is not working correctly. At least not anywhere like it was!!!!! Now it when entering app it showed the solar charging to estimated solar then drops to nothing. After update again it showed 0 charging on graph.

### 1/5 — RHC

*2026-08-04, version 2.6.1*

App w / latest download shows solar output 4.7kw at noon no clouds  compared  to estimate has also changed the whole history. Sorry app is not working correctly. At least not anywhere like it was!!!!!

### 5/5 — A must have for Powerwall and Octopus Energy

*2026-08-04, version 2.6.1*

Has solved a problem of draining the Powerwall when Octopus charges the car out of off peak hours. So much easier than staring at the app adjusting the backup manually. The £6.99 will pay itself back very quickly!!

### 5/5 — Top Quality App

*2026-08-02, version 2.6.1*

Absolutely amazing app. 
let’s you run your powerwalls so good saves you money and ease of use. 
try it out you will be so impressed

### 5/5 — Great addition to the Tesla app

*2026-07-29, version 2.6.0*

A must have for all Tesla solar system owners.  It really allows you to maximize the return on your investment!
