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.

Thanks for the report. The data is cached on the device, however there are some performance issues when swiping between months. These issues are getting fixed in the next version.

The app is really good but unfortunately doesn't integrate with the car which results in limited automation options. It would get 5 stars if I could add automation for the PW that can adapt the powerwall settings when dynamic charging my car. For example, read data from the car that it is being charged or if it could read data chargers such as ohme to see when the car is being charged. The current automation setting that can be used doesn't cater for when OI sets a charge rate at less than 2KW

Thanks for the review! You can create an automation based on house usage, e.g. whenever house usage exceeds 8kW. This is usually a clear sign of EV charging and can be used instead of the Wall Connector integration. Give it a try and let us know at feedback@netzeroapp.io if you run into any issues.

Glad I didn't pay for this as it gave a 1 month trial when I signed up. App didn't even make it past day 1. Everything started fine. It signed in to my Tesla and Octopus accounts and got the data. The first smart charge octopus did outside peak tariff and the app didn't stop the battery and change to grid. Tried then setting up automation based on price per kW but after going through setup, get to end and fails to setup the automation. Will forget this and struggle on trying to setup home assist

Send us an email to feedback@netzero.energy, there are no issues with the IOG integration so we suspect something was not configured correctly.

What's new

- New: Default backup reserve (Automation > Configuration). Automations can restore your default reserve, and Configuration shows what set the current one.
- New: Optimal backup reserve. Raises the reserve when lower solar no longer fills the Powerwall, as in winter, to hold more charge for an outage.
- New automation action: Set vehicle charging rate, for Tesla vehicles and EV chargers that support it.
- Bug fixes and small improvements.
