Simply an amazing app
This is a great companion for your Tesla, solar and powerwall system
If you don’t live in ConEd don’t buy
I’m in ERCOT, so this doesn’t work.
RHC
App wiped out my arrays, had to refigure, reinstall!!! Now working great again! It all happened with update w/estimates!!
Zero customer service
They don’t wanna talk to you they don’t wanna help you individually. What a poor excuse for customer service impossible to get any help. I appealed several times by email. And you can’t get your money back ever.
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. Tim 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. Tim

Great app. Complete product to improve the Tesla controller. Fun to use, educational for the user and allows complete control of the system…. User interface is quick to understand delivers complete understanding of the system and total control of the PV…
Comed hourly support
Thank you for the comed hourly support. Very welcome change. Looking forward to seeing how this saves us $$$ going forward. Edit: updated to zero stars. Subscriptions are terrible. Offer a single price like any decent person would!
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.
Missing Disconnect Grid
Solar produces enough to stay disconnected from grid. Right now the Powerwalls are not communicating to the Enphase connected Canadian solar micro inverters to shut down or reduce solar production when Powerwalls are at 97% causing power surges in the house. To stop the surge for now I need to reconnect to the grid. This feature is missing. I need the app to disconnect and reconnect to grid until this issue is sorted. Missing dollar savings and real time energy bill estimates for the month.
A lot of promise.
This is a good app, but it could be, and should be!, a great app. I paid the pro subscription so I could see solar string energy, but it only shows the first powerwall, and even at that, it shows it as 6 strings rather than the 3 it is. I can do the maths myself, but it would be better if the app did it and presented me with 3 strings. It needs to show the pv strings on my second powerwall, and for folks who have more than two too. I’m sure all of this will come soon enough, and I applaud Net Zero for all they are doing. I just want it all now!
Easy to use
The app automation has allowed me to take advantage of high sell prices for electricity while avoiding peak charges.
Time change?
Just realised that without touching my settings in over a year, the app has swapped midnight with midday. Thanks for that, for the past few weeks (or months!) my powerwall has been charging itself up during expensive peak time instead of off peak during the night.
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
Inaccurate estimates
Horrible estimate for how much electricity you “should” be producing. As an example, today it says I should produce an estimate 39Kwh when I’ll realistically produce around 8Kwh. I put my info in for my array and entered my location, which says is used to gather weather information, and still is terribly off on the estimate.
Solar String data
I'm unable to figure out how to see solar string data for my Powerwall 3 setup. Paid for the upgrade to get diagnostics, but still don't see it in the download. Any help would be appreciated
Excellent
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….
Superb functionality but…
Update 6 Sep 25: I didn’t choose to take up the subscription. Instead I needed to retest the Tesla app and categorically establish how much value I was gaining. After a full month I have my initial ‘real’ assessment. The flexibility of Netzero is undeniable. The native Tesla app is as annoying as ever. But from an entirely monetary perspective, with a bit of breaking to my rates I’ve seen no material change in my recovery, and certainly nothing to materially offset the subscription charge. I fully appreciate why Netzero were forced to go this way, but it looks like these API charges make any business case for this app unviable, which is a real shame. Really sorry guys- love your work and what you’ve tried to do, but you’re being squeezed out of the market. Original Review: I’ve been using this for 9 months now- it’s a real game changer and plugs some serious holes in the core Tesla powerwall control capability. The flexibility is second to none and the support provided is amazing - well worth a 5 star review. But now we need a subscription to take advantage of this. Don’t get me wrong, it’s worthy of a subscription - I’d been expecting this for a while and I’d gladly pay, but the fee is way over the top. I’m seriously going to have to reevaluate whether this is driving enough value on balance. Times are hard for everyone - Guys, thanks so much for all of your hard work and innovation but seriously, please reconsider the price you are asking people to pay!
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.
Net zero errors
I am a paid subscriber to Netzero app but it recently stopped alerts and continuously requires logging in again and under setting the error is “Error objects are not valid as a react child (object error” …”. There is no contact able support or contact details, hence connecting though the apps store to report. Paid customers should be able to contact support I would expect.
Too expensive
The app is great but it’s just way too expensive now. I’m willing to pay for it but it has to be at a price that makes sense, it’s counter intuitive to charge more than it’ll save over a month/year. I respect the work that goes into producing the app and don’t expect it to be free, I was ready to subscribe until I saw the price and it just makes no sense. Really disappointed. The app is 5 stars, but the price is way off the mark
Fantastic monitoring desktop/ipad app
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!
Total rubbish
We are paying for this app now, and the basic function of switch back the original reserve limit after IOG slots does NOT work
Great if you have a Tesla Powerwall
Having just had a Powerwall 3and solar arrays installed, my supplier suggested this app for providing much finer control of the system, particularly as I needed to potentially charge an EV and the PW3 simultaneously. The app works very well once logged into your Tesla account and does what is says. I now have special instructions (under automation) that permits simultaneous charging and it works just as needed. The app also provides better graphical information about how the three energy sources I know have (grid, battery, solar) are being utilised to meet my home demand. Technical support is also first rate with fast and useful responses. Well worth adding.
Not worth the subscription
All i wanted to do was turn my wall to charge at 11.30 until 5.30 under timed control then back to self powered for the winter months. Cheaper just to have a alarm set on the phone to do this manually. A lite verson with simple controls would bring you a lot more customers. This app is perfect for agile customers but not igo customers. Shame
Lack of support?
Is there any support for issues like when automations don’t run? I had an automation not run… It was just blank in the past runs… And then three days later it just showed up as had run when it absolutely had not and I can’t find any support ?
Great addition to the Tesla app
A must have for all Tesla solar system owners. It really allows you to maximize the return on your investment!
Was a great app but now overpriced & will undo any savings anyway
The new pricing model means the £100ish i would have saved from automation is gone. I would have considered for £25 a year but not for £70. More than my netflix subscription for a simple bit of automation. I will Switch to home assistant for now as will cost me less than £4. You priced yourselves too high guys
Helpful app
Adds a bit more flexibility to managing imports and exports. Would benefit from an option to use “if then, else” statements for greater control and changing conditions.
Great App but not Cost Effective
Fantastic app that enables a whole host of functionality not provided by the default Tesla setup. I understand the developer has overheads but I just cannot justify the subscription cost for the benefits gained.
Subscription model too expensive!
As one of the only ways to get dynamic Tibber pricing and Powerwall to work together, I‘ve been a very happy user of the app for this simple and only function. I don’t need any other other functions. Please consider a slimmed down subscription purely for this. You are abusing your monopoly position.
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.
$100 per year! What the…
Whoever determines your pricing model is smoking crack… who’s going to pay that? Nice product, but benefits case does not stack up. Good luck to you
Initial impressions weren’t great but improved with time and I can see this could be very useful.
I bought this app to work with Octopus Agile - it didn’t. Everything appeared to have been set up ok. My Tesla app said it was on the right tariff and not to edit it as was being controlled by NetZero but it only charged from solar (despite charging from grid and export being enabled and overnight prices around 3-4p/kWh and despite reaching 100% charging from solar it did not discharge come 4pm. For the £6.99/month it’s costing I have decided it isn’t worth it. I have set a manual schedule in the Tesla app and that actually seems to be working. Maybe if I got it working it would save me a few pence per day (so far it has cost me money) but I will in future be saving 23p a day from not paying for the app. Perhaps it’s my age. I really wanted something I could set up once and forget. I don’t want to have to power cycle my battery to get it to bring up options that should be there. Apps should just work, especially if they are paid for. I am sure that many people who are a bit more tech savvy than me will enjoy it but the instructions (if you can find them), particularly for automations seem to me to be written by techies for techies. I suggest the developers ask their grandparents to read through the instructions and make sure if it is intelligible for a layman before asking £70/year. I didn’t find the app at all intuitive. I was also puzzled that the battery wasn’t included in the list of Energy Devices (EV chargers and heat pumps, yes, but battery, no) making me think I must be missing something. I will, in fairness, say the developers do respond reasonably quickly but how much to’ing and fro’ing should one need. I was disappointed after the rave reviews on YouTube and the top reviews other purchasers have given (actually less top reviews once it becomes a paid app it seems). It obviously is a useful app for many people - particularly the tech savvy who probably are a majority of Powerwall owners- but sadly it isn’t for me. I do find it annoying that I had to spend £6.99 to find that out. If it had been a free app or even a free trial first I would just have moved on without bothering to leave a review. Update: one month on and things improved considerably. I think the initial problems may have been down to the battery being new and learning my usage. I decided not to try and be clever with the app and just leave it and the battery to manage my Agile tariff which it did pretty well. I have though decided that now I have a battery Octopus Go is a better tariff for me and that is quite simple for me to set up for the PW3 to manage as there are just two rates - peak and off peak. I have therefore cancelled my subscription. I am still able to see a bit more data on the free version of the NetZero app than is available just from the Tesla app so that is a real positive. If I was still on the Agile tariff I would have kept up the subscription as it saves an awful lot of work managing the battery myself and I would recommend the app in that situation. I have therefore revised my rating from 2 to 4 stars.
Not worth it.
Update one month not using Netzero. Had great functionality, but does not represent value for money. Still not worth it. Sorry. I’ve dropped the stars to two from four. Could you consider reducing overheads? -Tiers of automations based on how much you are demanding? (Setting a reserve charge state twice a day is very different demand to Octopus Agile/IOG integration). -Not limiting subscribing through Apple Store to reduce commission. -Allowing automations to run as background activity on a phone to reduce cloud running costs. -Having a one off paid for app that would raise some money. -Accepting a smaller profit margin for more customers, there will likely be competition soon. —- Used the app for a few months, has been quite nice to get extra functionality and automations not offered through the native Tesla app. However the new pricing proposed is not worth it for users like myself on a simple off peak tariff in the UK. I’m forecasting the extra increase to my bills may be ~£2 a month based on Tesla time-based control. £6.99 a month isn’t worth it, sorry. I would happily pay for a ‘lite’ service with some basic automations (Time based setting of backup reserve) or even pay for a standalone version that can be run from an old phone allowing local control rather than from the cloud. Appreciate your reason behind moving to the subscription model, sadly it’s not worth it for me.
Loved it until now
Great app, took a bit of tinkering to get right. It now it just works away in the background. I am however disappointed at the subscription cost that is now being introduced. Firstly it is advertised at $6.99/mth, but in the UK it is £6.99/mth, something is not quite adding up there with the exchange rate! Secondly I just can’t see the cost/benefit ratio paying me back £70/yr using the app. If it was maybe £3/mth that would be a little easier to accept.
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.
If it was cheaper I’d be tempted
It just feels like greed, the cost of the upcoming subscription. The issue is that for most of the year my feedback to the grid won’t actually cover the cost of this stupid subscription, whereas for about 3 months it will. It just makes no sense to be giving profit to this app across the year. I understand all the reasoning so please don’t reply, but i just want to suggest reducing the fees. People are sick to death of subscriptions and this one just seems absurdly high.
Good but could be improved
Provides better control over battery management than Tesla app. Estimated power production could be improved by allowing adjustments for shading times, especially during morning run-up and evening rundown.
Ok app but subscription is greedy
Come on £69 a year for an app! The app is ok but lacks features and charging that is just not on Madness
awesome tool
best application to automate powerwall functions and show the telemetry
Great… until expensive subscription charges are introduced.
Netzero is great, really like it, I do think the subscription needs to be way cheaper, it’s just too expensive. API costs are minimal… $1 per 1000 commands. Making £6.99 very excessive. Also under the grid usage where it calculates your energy cost import and export it would be handy to account for energy standing charges in that calculation.
Use this multiple times a day. Love it.
Just needs widgets. Unless I’m missing something.
Subscription cost far too high…but excellent for integration between IOG, PV, a PW2 and Zappi
Excellent app but the subscription cost is far too high to make economic sense. £70 annually is currently equivalent to 1000 kw on Octopus IOG. There is no way I could save anywhere near that amount of electricity using the app whose main use would be in the summer months anyway. Happy, as others have said, to consider a ‘lite’ version at a more reasonable cost. I do understand why the developer wants to monetise the app though.
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.
Another subscription
This app promises so much. But without subscription in August 25 it will be useless. The benefits of the app are quickly outweighed by the cost to have the app. A one off cost to purchase pro would have been acceptable. But all these subscription services are becoming intolerable and unsustainable.
Works well with Tesla
Much more useful app than the Tesla app. Excellent graphics. Monitoring of inverter and panels is good but would be better if it could retain the readings; strings have to be reread if you leave the page. Strongest feature is the automations. You do have to subscribe to the app for this feature but it is worth it as Tesla makes access to the API very difficult. It may be difficult to implement, but having an IF/THEN capability would be great. Also having a time-of-year condition could be useful for TOU users. Overall I am very happy with the app.
