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.

Excellent app. Makes it very easy to integrate with Octopus tariffs to make sure you are getting the best from your system. Web version also available allowing the dashboard to be seen on the desktop. I have yet to use any of the automations, but it's simple and intuitive to add them if you have specific needs or are looking to squeeze every last drop of value out of your system (e.g. set battery to dump all remaining charge to your export tariff just before it recharges on cheap rate).

This is a brilliant App. Before I was able to export I used the Automation's, which weren't easy to set up, but I eventually managed to get them to work. Now I can export, I've found the automatic settings which just work. it's quite unnerving to see the export drop the battery charge, but we haven't run out yet. The only thing I can't see is if the 'system' will discharge before Octopus have a free session, or if there's a way to manually discharge the battery ahead of a session.

Thanks for the review! Octopus free sessions are unfortunately not automatable, because the data is not made available by Octopus, and there is no easy way to trigger the Powerwall to discharge.

What’s new

- Removed the Virtual Power Plant (VPP) event automation triggers and the CA DSGS VPP estimate, as Tesla no longer provides VPP event data to third-party apps.
- Bug fixes and small improvements.
