Very Good App - Can Be Even Better

Can really dial in your system with this app, and is generally intuitive and straightforward. Over all worth the cost once you learn it.

Would be great if you could select an automation after reaching a predefined trigger like “After my car finishes charging, reset my Powerwall from “Maintain Charge” to “Self Powered” so I don’t have to tap the grid at night once my car finishes charging.

Gone wonky

Edited: Netzero responded right away and identified a problem that occurred when using the app in a different time zone than the Powerwall. This is resolved and working great! 5 stats for customer support!

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.

An absolute must

After Tesla replaced our PW2 with a 3, I found the software was costing us money, not saving it; the new algorithm, simply put is garbage. I gave it a few months to see if it would 'learn' but it actually got worse! That's when I found Netzero. Netzero puts control over your expensive in your hands, not Tesla's. Since using it I have set up rules that govern how the battery works in ways the Tesla system never could or would, in turn saving us a lot of money... like you'd expect. If you have a Powerwall, Netzero is a no brainer must have.

Thanks for the review!

NetZero for Powerwall

This a great app for understanding and managing the Tesla Powerwall and other devices.

Save your money, overpriced !

Difficult

It is very hard to log in on an iPhone. It will not do eye recognition nor does it remember my password.
But it is useful so I am persevering.

In 2026, just had a repeat of this problem and it took two days to restore access. The problem is in the Tesla part of logging on, but this is still part of NetZero app.

If you have a Tesla Powerwall, you need this app!

You really need this app to control the battery properly to manage the tariff structures. The automations are fantastic. So good that you can input time, backup charge, usage, grid charge, energy flows. I only wish there were: if x then y possibilities at a particular point in time rather than energy flows crossing thresholds. You’ve done a lot of work to put this together and happy to pay the cost.

Thanks for the review. More complex automation triggers are on the roadmap.

Netzero for Tesla PW3

Does the job with automation stops my PW3 charging my EV and charges the power wall while ev charging on cheap rate

Great Info

Use this app many times a day to monitor battery, solar and EV charging. Also helps with automating the Tesla configuration. Have my ID.4 connected as well. Just wish I could connect my Bolt.

Excellent Tesla PowerWall controller

Took a little while to fine tune, but now works EXACTLY as I want - sets charging to off peak times and allows me to charge my car without draining my battery. The only caveat is that the subscription could be a little cheaper to improve my savings and justify its use over Home Assistant.

awesome tool

best application to automate powerwall functions and show the telemetry

Netzero really does enhance TESLA Powerwall

I rarely use the Tesla App as Netzero offers so much more integration and automation. It integrates well with Intelligent Octopus Go if you use the paid version and found it invaluable when I had some smart meter issues to prove to Octopus what I exported. It also performs cost calculations. I have recently connected my Heat pump to the app, though automation is currently limited, hopefully this will develop in time

NetZero is a Life Saver

I’ve used it for the last 9 months and couldn’t live without it now..! The App gives me all the info I want, runs seamlessly in the background or gives me the automations which are simple to set up and enable me to run my Solar/EV/House and exports exactly as I want to. Thank you team..!!!

Excellent Companion

This app gives you more control of your Powerwall. The Tesla app is great but it leaves some gaps for efficiency. Netzero closes that gap and gives you full control to maximize the efficiency of your device.

Good App

I run this app on my Mac. It lets me monitor my solar array and Powerwall, tracks sell/buy to/from the grid, and gives me a net$ at the end of each day. 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!

Simply the Best

I’ve been using Netzero for a few years and it continuously improves.

Wow

All of the data unlocked !
Just started using the automations - my calculations are the app will pay for itself in less than 6 months.

Good but too expensive

I really like this app and I used it quite a lot before the subscription model kicked in. Since then there have been many useful improvements, but for me the annual cost is way more than I would save each year. The Tesla AI works that well for me that I rarely need to tweak anything. I do use the free version for the graphs though and the developer has been responsive to questions I have had.

A Must-Have For Powerwall 3!!

Whilst the Tesla app is good, this app is much better. It expands its UI to full screen on an iPad and has an excellent web browser interface as well. Great dashboard. The automation functionality is brilliantly powerful but simple. I know you have to pay a subscription for the advanced features but it will be money well spent. Anybody who has a Powerwall 3 will love this app.
