TRMNL

See your kWh, your ERE's and your charging sessions on a TRMNL e-ink display.

TRMNL is a small e-ink display that fetches new data every few minutes. With a private plugin it shows what you charged this year, your ERE's and your latest charging sessions. The recipe is ours, the display and its plugins are TRMNL's.

What data the app reads

The app uses an API token. It reads everything your token may read:

  • profile
  • chargers
  • charging sessions
  • energy and ERE's
  • ERE position

Read only. The app cannot change or start anything.

Connect

  1. 1In your dashboard, open Developer › API › Recipes.
  2. 2Copy the TRMNL recipe. Your token is already in it.
  3. 3Create a private plugin in TRMNL and paste the settings and the markup.

Stop

Revoke the token under Developer › API in your dashboard. Every app with that token then loses access.

We build and maintain this connection ourselves. Last checked on 28 October 2026.
