The full walkthrough

These nine screens were captured directly from the device. The recordings predate the newer manual-hold status line; current controls are documented above and in Controls and night mode.

Turn toward comfort
Solid fill is the mattress temperature; the moving span shows the distance to your target.
Cooling works the same way
The cap marks your target as the mattress cools toward it.
Then it goes quiet
The loader disappears once the mattress reaches the target.
Off is a click
Click or tap power. The arc empties and the number dims.
Hold for settings
A ring fills over 1.5 seconds. Releasing early cancels.
Your side is a preference
Choose Left or Right once in Settings. It stays selected.
Red after ten
From 10 pm to 7 am: red on black, 20% brightness, no sounds.
Glanceable at 3 am
After five seconds at night, only the number and a status dot remain at about 1% brightness.
Wake without changing anything
The day display dims after ten seconds. Once safe wake arms, the first input only wakes it.

Rotating the encoder moves the target and the arc settles when you stop. Silent recording captured from the device framebuffer.

The project includes a base and faceplate for M5Stack Dial v1.1. Use the MakerWorld print profile  or the repository’s 3MF files .
