Build and connect the Dial

What you need

An M5Stack Dial (ESP32-S3 with a 240 × 240 round touchscreen).
A USB connection to your computer and PlatformIO.
Core running on your Pod and reachable on your Wi-Fi network.

Configure and flash

Install PlatformIO through its VS Code extension or CLI, then clone the firmware:


git clone https://github.com/sleepypod/m5-rotary-dial.git
cd m5-rotary-dial
cp include/credentials.h.example include/credentials.h

Edit include/credentials.h with your Wi-Fi SSID and password. Keep this file private and out of commits.

Set GMT_OFFSET_SEC and DAYLIGHT_OFFSET_SEC in include/config.h for your location. These are numeric offsets, so check them when daylight saving time changes. For example, UTC uses zero for both.


pio run --target upload

Connect the device over USB and select the appropriate upload port if PlatformIO does not detect it automatically.

Find the Pod

On startup, the Dial joins Wi-Fi, tries mDNS discovery, then falls back to its saved/default IP. The documented default is 192.168.1.88; your Pod may have a different address.

Open settings by holding the center or tapping the gear:

Select Discover Pod to retry discovery.
Or select Pod IP Address, turn to set each octet, and tap to save.
Choose Side and confirm left or right.
Choose your temperature unit and night mode.

The Pod service advertises _sleepypod._tcp on port 3000. Devices must be able to reach each other on the LAN.

Verify

Check that the Dial’s reported temperature matches the selected side in Core. Turn one detent, wait for the update, and confirm the target in the web app. If synchronization fails, follow connection troubleshooting.
