I'm currently using a couple of switches from Retouch, connected to a standalone Zigbee gateway (LAN cable) which is then connected to my Deco M4 router.

All these are managed via Tuya. Worked great for the first 3 months and then for some reason the zigbee gateway keeps powering off by its own, tried all the troubleshooting steps but to no avail.

Now I'm currently looking at Echo 4th Gen (as now I'm using Echo Dot 4th Gen) as it comes with built-in Zigbee Gateway features which means that I do not need to rely on a separate Zigbee gateway any longer.

Anyone currently using Echo 4th gen and utilising the Zigbee gateway features?
