LaMetric
lametric
The LaMetric integration lets you integrate your LaMetric TIME smart clock with Home Assistant, so you can display notifications, charts, and other visual updates on the device.
In Apple Home through HomeKit Bridge
What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.
| Entity | Shows up as | Note |
|---|---|---|
switch | Switch or outlet | |
button | Button (as a switch) | |
select | Mode picker (as switches) |
What people report
LaMetric TIME is controlled over the local network; 2025.1 broke notifications without a sound for pre-2022 devices.

| LaMetric TIME (pre-2022) | Partly works Local | 2025.1 notifications only appeared when a sound was specifiedSaved copyThe problem After installing 2025.1.0 notifications in Lametric Time works only in case a sound is specified in the 'data' section (see attached image for an example) Otherwise no notification is displayed. Before 2025.1 update it worked in any case. Specify that the device is a pre-2022 (do not know if the problem occurs also in 2022+ devices) In my case i have some type of notifications than needs to be without sound, and specifying 'null' or 'none' in the sound field does not fix the problem. ### What version of Home Assistant Core has the issue? 2025.1.0 ### What was the last working … Excerpt saved from GitHub on 2026-10-23. | Issue #134743 · 2025-01 |
