SASWG-04-RF-WIFI（TY) Home Smart TUYA WiFi Gateway, Include Power Adapter（UK Standard）

I purchased this hub to integrate several SEA802-DF I had recently purchased. Unfortunately, I found the set up of the box impossible when following the provided instructions, and I found the item was missing a power adapter upon arrival.For anyone else who faces a similar issue: the manual, which is poorly written, specifies that the Tuya Smart app should be used to connect to the gateway by selecting an 'Alarm' sensor from the device list, placing the gateway into WiFi mode (quick flashing blue light), and letting it pair. This proved to fail every time. The only way I was able to get the gateway to successfully pair with the app was to instead put the gateway into AP mode (slow flashing blue light), and manually connect my phone's wifi to it. Only then did the Tuya Smart app recognise the device (as a Gateway mind you, not an 'Alarm'), and I was finally able to set up the system.The fact that the gateway arrived without a power adapter was very much insult to injury. If I had been aware of these problems prior to purchasing and Saswell items, I would have gone with a different brand.
