Device Card

Device card

From version 1.7.0.

A small card for one Thread device – for a room dashboard, without the whole map. It comes with Thread Pulse (same file, nothing extra to install).

What it shows

Line	Content
Header	Name, role in the Thread network and area; a green dot when the device is reachable, red with not reachable when Home Assistant reports it unavailable
Parent	Battery and end devices: the router they talk through, with its signal (green / orange / red as on the map). The value measured by the router is used when the router reports it, as on the map
Links	Routers: how many other routers they reach, and the best signal
Battery	Level and, once there are 14 days of statistics and a measurable drop, the battery forecast
Chart	Signal of the last 7 days – to the parent, for routers the best router link. It is the trend that Thread Pulse records while its map is open somewhere; hours without an open map are gaps

Wi-Fi and Ethernet devices only get their name and a note – they are not part of the Thread mesh.

Tap the card to open the Thread Pulse map with this device selected and zoomed to (option map_path), or – without map_path – the device page of Home Assistant.

Adding it

In the dashboard editor: + Add card → Thread Pulse – device → choose the device. It takes the full width of a section and grows with its content; make it narrower in the editor if you like. Or in YAML:

type: custom:thread-pulse-device-card
device: 01d78d2a0af558eb4decc71b82676fee   # device ID – an entity ID of the device works too
name: Schalter Küche                       # optional
map_path: /dashboard-network/thread        # optional: the view with the Thread Pulse map

Option	Description
device	Required. The device (device ID), or one of its entities (sensor.front_door_battery)
name	Name shown on the card; empty = the device name in Home Assistant
map_path	Path of the dashboard view with the Thread Pulse card. Tapping the device card opens it with ?tp_device=<device ID>, and the map selects that device. Empty: tapping opens the device page
language	Like the main card; empty = Home Assistant language
demo	true (battery device) or router – invented data, e.g. to try the look

Good to know

• Like the map, the card needs an administrator account (it reads the Matter diagnostics).
• To name the parent it reads the cached diagnostics of all Matter devices – once for all device cards on a page, at most every 5 minutes. No device is queried, battery devices are not woken up.
• The chart only has data where the Thread Pulse map was open (for example on a wall tablet). Without that, the card says so.
