Tuya Matter Integration updating

Devices & Integrations Connected Things
1

Hello everyone

I connected a Tuya Matter Hub to Smartthings via Matter. This is working well so far and the hub has brought all Zigbee devices from the Smart Life app with it, even those that were not previously transferred to Smartthings via the cloud connection. But now I noticed that when you connect a new device to the Tuya Hub, it doesn’t appear in Smartthings. The device only appears as soon as you disconnect the hub from Smartthings and set it up again. Does anyone know a trick on how to take over the devices with a hub that is already connected? Thank you

There is a known matter bridge issue that applies to all matter bridges right now, but it’s not quite the same as what you’re describing, and fortunately is a bit less of a headache.

I haven’t tried it specifically with tuya bridge because I don’t have one of those. But with both SwitchBot and Aqara matter bridges, when you add new child devices to the matter bridge, you have to reboot both the SmartThings hub and then the matter bridge, and then that updates the matter connection and you get all the available child devices. But you don’t have to actually remove the bridge or rebuild Any routines or anything. Just power down and power up again on the two hubs.

So you might try that and see if it works. Either way, let us know what happens. It’s possible there’s a separate different issue with Tuya. :thinking:

This is a good idea. Thank you. I will test this

I tested it. This is the solution. Restart of both bridges and the device is here.

I hope in future there will be a better way to to this. But it works

Hi Daniel, which Tuya Matter Hub do you have? I’d like to get one and integrate it with Smartthings just like you did. Thanks.

I have the Moe’s ZigBee to Matter Gateway. It works pretty good with ST. See my write ups.

Thanks for the quick reply. I’ll go with that one.
Additional question: does anybody know what is the network that both hubs use to “talk” to each other? Matter over Wifi, over Thread, … ?
My issue is that I will have the ST hub at home and the Moes hub at the garage, linked via a powerline. So, they’ll both be on the same IP local network. But not the same WiFi.
Will this setup work?

The Moes hub uses an Ethernet cable to connect to your network.
