Usage

Configure devices

In config.json devices[], fill name / name_zh / id / ip / token / model, etc. BLE sensors also need mac and ble.key. You can also manage them in the Config Web UI.

Optional hotkey (a–z / 0–9, q reserved) for one-key jump; colored hotkey letters appear next to names in list / grid.

Groups go in device_groups[], members linked by device id.

View switching

• Detail: full status and type-specific controls for one device
• List l: dense browsing
• Grid g: icon grid, good for quick on/off
• Group d: batch control by room / scene

With no devices, the tip prompts u for setup.

Communication

• Most Wi-Fi devices: LAN miIO (same subnet as Cardputer)
• Temp/humidity, motion / remote, etc.: BLE scan of advertisements

Update mechanism

Like Cursor, Mijia runs miIO query / control on a FreeRTOS background task. The main loop handles keys, BLE polling, and partial redraws; never draw from the task. Grid cell refreshes are queued on the main loop.

Background task

Action	Behavior
Enter App	Connect WiFi → pull current device status
Switch device / page	Bump gen, invalidate unfinished old work
On / off / brightness	Async SET, write back to UI when done
Grid / group	Queue in order QUERY or batch SET for page devices
Leave App	Cancel work, wait for task exit, turn off WiFi immediately, stop BLE

Single-device query timeout ~2s; late results are dropped and status shows timeout. If a task is already running, new work is staged and chained when it finishes.

Wi-Fi devices (miIO)

• Entering Mijia auto-connects configured WiFi, only while Mijia is foreground; disconnects on leave.
• Connect time is not counted in device query timeout; QUERY starts after connect.
• After control ops (on / off / brightness), devices like air fryers get a delayed QUERY to sync lagging state.

BLE devices

BLE must not scan inside the background task (can crash). The main loop handles it non-blocking:

Mode	Trigger	Notes
Background listen	Auto on enter Mijia	~30s per round, rotates BLE ads into per-device cache
Focused scan	Detail r	Interrupts background; focuses current device ~30s; then resumes background listen

Detail shows cached reading and Xs ago age; with no cache shows listening; r forces refresh. Grid / list BLE cells use cache only, not the miIO queue.

Partial refresh

• Detail: icon and right control panel redraw separately; prefer dirty regions on status change.
• Grid: after task write-back, changed cells are queued for main-loop refresh to avoid full-page flicker.
• Group: bottom on/off / brightness bar can partial refresh; batch ops run member order and summarize success / fail.

Local timer

Air fryer detail: remaining time from the device ticks locally every second in the right panel without waiting for the next QUERY.

Supported device types (model)

Firmware classifies by model string (see mijiaClassifyModel). The table below is by control capability; unlisted models fall into GENERIC (still on/off; matching icons if any).

Type	Match rule (examples)	Capability summary	Icon
LIGHT	yeelink.light.*	On/off, brightness; some CT / hue	see below
FAN_P5	exact dmaker.fan.p5	Speed, oscillate, mode, swing
FAN_GENERIC	model contains .fan.	Levels 1–4
AIR_PURIFIER_F20	exact dmaker.airpurifier.f20	Mode, speed, AQI, etc.
AIR_FRYER	contains airfryer or .fryer.	Temperature, time
PLUG	contains .plug.	On/off
SENSOR_HT	contains sensor_ht or .ht.	BLE temp/humidity
BLE_EVENT	contains .motion. / .remote.	BLE event device	(default icon)
GENERIC	other	Basic on/off

Light model notes

model trait	Extra capability
yeelink.light.lamp2	CT ~2500–4800 K
yeelink.light.lamp1 / lamp4	CT ~2700–5000 K
contains .mono	Fixed CT (not adjustable)
contains bslamp2 / color8 / color2	j/k hue

Config examples: yeelink.light.lamp2, miaomiaoce.sensor_ht.t2.

Device icon assets

Icons match model substrings (longer names first). Assets from firmware data/icon/device/:

basename	Off	On	Typical model fragment
airpurifier			airpurifier
bslamp2			bslamp2
lamp2			lamp2
light			fallback for models containing light
fan			fan
fryer			fryer
plug			plug
sensor_ht			sensor_ht
camera			camera
cooker			cooker
juicer			juicer
wifispeaker			wifispeaker
default			unmatched

Grid / list also use *_25w.png small icons; on device, same-name .rgb565 bake files are preferred for faster draw.
