Tuya mesh supports 128 sub-devices for one home. This number can be extended to 250 by activating a customization service. The number of devices connected to a gateway is not limited. More than one Tuya mesh gateway can be deployed in a home. However, compared with Bluetooth mesh gateways, increasing the number of Tuya mesh gateways does not increase the number of nodes that can be added, and Tuya mesh gateways will be counted against the number of sub-devices. Tuya mesh is a private mesh protocol, while Bluetooth mesh is a standard protocol launched by Bluetooth Special Interest Group (SIG).
