Gaoducash Gateway Protocol Comparison
Connectivity protocols
Product A is a dedicated ZigBee 3.0 hub that bridges ZigBee devices to your 2.4GHz Wi-Fi network. It supports all Tuya ZigBee products like motion sensors and smart sockets. Product B adds Bluetooth 5.0 to the mix. This multi-protocol design lets you control ZigBee, Bluetooth, and Wi-Fi devices in one place. You can use Bluetooth fingerbots and thermometers alongside standard ZigBee sensors. If you only have ZigBee devices, Product A is sufficient. If you have Bluetooth gadgets, Product B covers more ground.
Device capacity
Product B explicitly states it supports up to 128 Tuya smart home devices. This includes a mix of ZigBee and Bluetooth products like leak detectors and window sensors. Product A does not list a specific device limit in its specifications. It describes itself as a bridge for whole-house linkage but leaves the capacity undefined. If you plan to build a large system with many sensors, the stated limit of Product B gives you a clear ceiling. Product A might handle fewer devices, but the data does not confirm a hard cap.
Physical dimensions
Product A measures 3.06 inches by 3.06 inches with a height of 0.98 inches. It is a square, slightly thicker unit. Product B is much smaller, measuring 1.88 inches by 1.88 inches with a height of just 0.4 inches. Product B is compact and fits easily into tight spaces without dominating a shelf. Product A is larger and may require more visible space. If you prefer a discreet hub that blends into the background, Product B is the smaller choice.
Smart home compatibility
Both hubs connect to the Smart Life and Tuya apps for remote control. They both integrate with Amazon Alexa and Google Home for voice commands. You can link them to trigger automations based on sensor data. Product A mentions local linkage and group control services. Product B also supports device sharing with family members and multiple mobile phones controlling the same device. Both offer identical voice control ecosystems. The core smart home experience remains the same regardless of which hub you choose.
Warranty coverage
Product A includes a full 2-year warranty. Product B also offers a 24-month warranty for its Alexa smart hub. Both manufacturers provide the same duration of coverage for defects or issues. You do not gain an advantage in warranty length by choosing one over the other. The support period is identical for both units. This factor does not influence your decision since the protection terms are equal.
Which Gaoducash Gateway Fits You
You own many Bluetooth sensors
Product B supports Bluetooth 5.0 alongside ZigBee 3.0. This lets you connect devices like Bluetooth thermometers and fingerbots directly. Product A only handles ZigBee devices. If your setup includes Bluetooth sensors, Product B is the necessary choice to keep everything in one hub.
You want a compact hub
Product B measures 1.88 by 0.4 inches. It is significantly smaller and flatter than Product A. Product A is 3.06 inches square and nearly an inch thick. If you need a gateway that takes up less space on a shelf or outlet, Product B is the better fit.
You have many ZigBee devices
Product A is a dedicated ZigBee 3.0 hub. It focuses solely on bridging ZigBee devices to your Wi-Fi. Product B also supports ZigBee but adds Bluetooth. If you do not use Bluetooth devices, Product A provides the standard ZigBee connectivity you need without the extra protocol complexity.

Frequently asked questions
Can I use both Gaoducash hubs at the same time?
Yes, you can operate both gateways simultaneously in the same home. Each device connects to your Wi-Fi network independently. This allows you to separate devices by protocol or room. Product A handles ZigBee devices while Product B manages both ZigBee and Bluetooth Mesh. You do not need to choose just one if your setup requires distinct zones.
Does the Tuya hub support Google Home?
The Gaoducash Tuya ZigBee 3.0 Gateway Hub primarily supports Alexa and the Tuya ecosystem. The product data does not list Google Home as a compatibility option for this specific model. If you require Google Home integration, you should consider the other Gaoducash gateway, which explicitly lists Google Home support alongside Alexa and Tuya.
What are the physical dimensions of the ZigBee hub?
The Gaoducash Tuya ZigBee 3.0 Gateway Hub measures 3.06 inches in width and length, with a height of 0.98 inches. It has a wired color finish. The alternative model is smaller, measuring 1.88 inches square with a height of only 0.4 inches. The compact size of the second unit makes it easier to place in tight spaces.
Is the second hub a Bluetooth or ZigBee device?
The second gateway, model Bluetooth Zigbee Hub-2, supports both Bluetooth and ZigBee protocols. It is designed to bridge mixed smart home setups. This allows you to connect Bluetooth sensors and ZigBee devices through a single unit. The first hub is dedicated solely to ZigBee 3.0 devices, so it cannot connect Bluetooth products.
Do I need a separate app for each hub?
Both gateways operate within the Tuya ecosystem. You likely use the same Tuya Smart or Smart Life app to control both devices. The first hub focuses on Tuya ZigBee automation. The second hub also uses Tuya but adds Bluetooth Mesh support. You can manage all connected devices from one interface regardless of the protocol used.
Which hub is better for Alexa voice control?
Both hubs support Alexa voice control. The Tuya ZigBee 3.0 Hub integrates with Alexa for standard ZigBee device commands. The ZigBee & Bluetooth Mesh Hub also supports Alexa. However, the second hub adds Google Home compatibility. If you rely heavily on Google Assistant, the second model offers broader voice assistant support.
