Site Look Refresh

Site wide we have reworked how things look and have moved toward making building blocks of the site reusable across different pages. This is still a work in progress.

Live Data

One fresh change is the page header how has more context around the recent flow of energy for your site.

Breaking up the Trmnl View Into Components

How we render information to Trmnl has been completely overhauled and the Trmnl view has been broken up into components. Each component can be added or removed from a screen you configure.

Trmnl Screen Management

The new Trmnl plugin management UI supports configuring up to 3 screens. The screens will be rotated, like a carousel, with each refresh of your Trmnl device. You can control the order of screens by dragging them to re-arrange them as you like.

To try out this new Trmnl configuration experience, go to your site settings tab -> Manage Trmnl Plugin -> Connect with Powerwall Energy Usage

New Battery Level Component

We recently started tracking history for your battery’s state of charge. This improvement allows us to chart your battery’s charge level during the day. Here is a screen showing energy usage along with battery charge level.

Because the battery charge level uses a lot of vertical space we also added a “glyph version” which just shows battery level indicators when significant changes occur.

As always let us know what you think.

January 2026 Refresh

We've just deployed some improvements to enhance your energy monitoring experience:

  • Site Site navigation has been simplified.
  • Interactive Charts: The site page charting is not more granular with 5 minute intervals.
  • Load Detection and Tagging: This experimental feature will allow you to tag your electrical loads. The load detector will automatically tag loads near cheaper tariff boundaries with the tag Arbitrage Candidate.

  • About: There is a handy About page that explains why this app exists.
  • News We added a site news feed feed for important announcements and updates. We also have a Discord Server you can join.

We would love to hear feedback from you about these changes, and any other suggestions you may have. You can reach us on the Discord Server
