About
TRMNL is a built-in Home Assistant integration that connects TRMNL devices through the vendor's cloud. It adds sensors for battery voltage and Wi-Fi strength, a switch for sleep mode, and two time entities for when sleep starts and ends. Setup happens in the UI and asks for the API key of a TRMNL account. New devices appear without setting the integration up again, and devices that no longer exist are removed automatically. Connection settings can be changed later without removing the integration, and a diagnostics file can be downloaded for bug reports.
