Casper Glow
casper_glow
The Casper Glow integration allows you to control your Casper Glow light from Home Assistant over Bluetooth. The Casper Glow is a portable dimmable light designed as a sleep aid, featuring a gentle dimming sequence that gradually lowers brightness to help you fall asleep. You can incorporate it into your bedtime automations to control brightness levels.

| Casper Glow | Partly works Local | Five brightness levels; Casper app can block the Bluetooth linkSaved copySupported devices: Casper Glow (identified as "Jar" over Bluetooth). Limitations: Brightness is limited to five discrete levels. The integration maps these to the Home Assistant 0-255 brightness scale, snapping to the nearest supported level. The integration communicates over Bluetooth, so the light must remain within range of the Home Assistant Bluetooth adapter. Only one Bluetooth connection to the Glow can be active at a time. If the Casper app is connected, Home Assistant may not be able to reach the device. Excerpt saved from home-assistant.io on 2026-10-23. | Docs |
