What is the difference between MESH devices and Wi-Fi devices? (1) MESH devices are connected through a gateway, even if many MESH devices are connected at the same time, they do not take up too much bandwidth and do not affect the response speed; Wi-Fi devices can be connected directly, but the more Wi-Fi devices are connected, the more bandwidth they take up and the slower the response speed. Therefore, Wi-Fi is suitable for networking and controlling fewer devices, such as table lamps, ceiling lights, etc., while MESH is suitable for controlling multiple devices together, such as light bulbs, downlights, spotlights, etc. (2) Multiple MESH devices can be connected quickly and simultaneously with just one word (currently up to 10 devices are found at a time), whereas Wi-Fi devices need to be manually paired and connected one by one. Purchase tips: Use with BLE MESH Gateway,If you don't have a gateway, you can add the switch directly to the TUYA Smart App to enable Blue-tooth control of the switch from your phone. What is the maximum installation distance between wireless switch and the gateway? In different indoor environments, the working distance between sub-devices and gateways is different. For use in everyday home environments, it is recommended that the distance between the sub-device and the gateway be no more than 10 m and that there be no more than two concrete walls in between.
