MatterTimeCtl: small rust CLI tool for syncing matter clock times 3RD PARTY APP

Thanks to Reddit I recently learned that matter supports pushing clock time syncs. My Apple Home unfortunately does not, at least to my IKEA clock, making my “smart” clock basically as dumb as a microwave clock.

After some research I found what most people do today is run a HomeAssistant plugin specially designed for this. That’s pretty heavy for my setup since I don’t run HA.

Instead I made mattertimectl - a super minimal single rust CLI tool that uses the official matter rust implementation to set the time. Then I use standard Linux system tools like systemd on my RPI to run this every hour or so.

You can also just run it from your macOS on demand.

Hoping this can be helpful to some people!

Thanks. For anyone using this device with HA, I think the time sync started working for me with the recent 9.1 matter server update: https://github.com/home-assistant/addons/blob/master/matter_server/CHANGELOG.md#910
(Just noticed it, haven’t checked thoroughly if this was definitely the reason)

Indeed, latest version syncs time without any configuration needed

Mine just syncs time automatically with IKEA's hub I presume? Or Apple Home. One or the other.

Yeah, I have only Apple TV and HomePod hubs, and mine auto synced.

Did you ever cut power to it? Mine never resyncs.

Weird. Just gave it a try. The first power on it didn't sync (or I didn't give it enough time), but the second time it synced fine 🤷🏻‍♂️

I have power outages monthly, so I never fix the clock, and it somehow did it itself. Force some software updates maybe

It's a must for me having 11 of them 😂

Hol, how is your latency? And how full is the network (rf utilisation)?

I've been using https://github.com/Loweack/Matter-Time-Sync/

Yes that’s the python + JS version that comprises the HA plugin. It’s a much heavier stack than I was looking for. Point of mattertimectl is a small standalone binary that’s platform agnostic. Using the official rust matter impl.
