I’m looking for a gateway that is compatible with Tuya/Smart Life, supports Zigbee 3.0, and-most importantly-has explicit support for Zigbee Green Power (ZGP) for use with batteryless switches.
The gateway should be able to handle local automation (contact → lamp) even if the internet is down, and ideally support 30–50 Zigbee devices.
USB power and a compact form factor are preferred.
If you know of any models that truly support ZGP (not just Zigbee 3.0), I’d appreciate recommendations or user experiences.
Use case is for a professional care facility, so stability and proper documentation are essential.
Most (if not all) Tuya Zigbee devices do not support binding.
